FRQ 1: Growth hormone and Insulin
b) Identify a dependent variable i the experimental design. Identify a negative for the effects of hormone addition. Identify a likely reason why the researchers continued their experiment for 240 minutes.
The level of phosphorylated signaling protein is the dependent variable, and the zero time point, at which the hormone is introduced and may take some time to begin acting, serves as a negative control for the effects of hormone addition.
A necessary hormone is an insulin. Blood sugar levels are regulated, and it aids in the conversion of food into energy. Your body can't produce enough insulin or can't use it correctly if you have diabetes. For injection (shot), injectable pen, or pump administration, your doctor may prescribe human-made insulin. Insulin powder can also be inhaled.
Your pancreas secretes insulin, a hormone that naturally occurs and aids in the body's usage of sugar as fuel. The inability of your pancreas to produce or release the insulin required to regulate your blood sugar levels may lead to diabetes if it doesn't function as it should.

Which of the following statement best describes how bacteria in a hot spring control the fluidity of their plasma membrane?a. They decrease the percentage of lipids with unsaturated hydrocarbon chains in their plasma membrane.b. Because they don't synthesize cholesterol, they cannot control membrane fluidity and therefore have a very fluid plasma membrane.c. They use cholesterol to prevent membranes from becoming too fluid.d. They form lipid rafts to prevent too much fluidity.e. They increase the percentage of lipids with unsaturated hydrocarbon chains in their plasma membrane.
e. They increase the percentage of lipids with unsaturated hydrocarbon chains in their plasma membrane. It is useful to measure the fluidity of bacterial cytoplasmic membranes using fluorescence polarisation techniques.
Bacteria actively regulate membrane fluidity in response to changes in temperature, pressure, ion concentrations, pH, food availability, and xenobiotics by altering the composition of their lipids. By altering the relative ratio of saturated to anteiso-branched fatty acids, their membrane fluidity is modified. When either the temperature or the amount of unsaturated lipids rises, membranes become more fluid. Cells control the production of lipid desaturases, which maintain a vital equilibrium between saturated and unsaturated membrane lipids, to maintain ideal membrane fluidity during temperature fluctuations.

homozygous for the three dominant traits: blank.target 1 of 4 homozygous for the three recessive traits: blank.target 2 of 4 heterozygous for all three characters: blank.target 3 of 4 homozygous for axial and tall, heterozygous for seed shape: blank.
An organism can be homozygous dominant or homozygous recessive depending on whether it possesses two copies of the same allele in the dominant or recessive chromosome. When an organism possesses two distinct alleles of the same gene, it is said to be heterozygous.
What is homozygous dominant homozygous recessive and heterozygous?The phrases genotype, phenotype, and trait are derived from the alleles of a gene that are present in an organism and the physical effects. A specific set of alleles for a certain gene makes up an organism's genotype. Accordingly, the flower-color gene may produce the genotypes red-red, red-white, and white-white in the pea plants mentioned above, for instance. An organism's allelic combination manifests physically as its phenotypic (genotype). There are only two potential phenotypes for pea plants when the red allele is dominant and the white allele is recessive. While plants with the white-white genotype will have the white phenotype, both the red-red and red-white genotypes will result in plants with the red phenotype.Using the aforementioned human examples, it is also possible to show how genotype and phenotype are related. People who have the normal-normal or normal-mutant genotypes for cystic fibrosis have the normal phenotype, whereas those who have the mutant-mutant genotype have the disease phenotype. When it comes to Huntington's disease, those with the normal-normal genotype exhibit the normal phenotype, whereas those with the normal-mutant or mutant-mutant phenotypic exhibit the diseased phenotype.To Learn more About homozygous dominant refer to:

Fertilization is most likely to occur when intercourse occurs __________ although sperm can live in the woman's body as long as __________ after ejaculation.
Thus, even if sexual activity occurs a few days after ovulation, fertilisation can still take place. An oocyte, on the other hand, can endure.
Usually, the fallopian tube that connects an ovarian to the uterus is where fertilisation occurs. An embryo begins to develop if the fertilised egg successfully passes through the fallopian tube & implants in the uterus. There is sporadic contact between both the egg and sperm. The egg sleeps for an additional 30 hours until it reaches the ampullar-isthmic junction, a particular area of the tube. In this section of the tube, the sperm and egg unite to form the fertilised egg. The fertilised egg then starts to quickly fall toward the uterus. Capable sperm can connect to the oocyte and penetrate to the zona pellucida of the egg by releasing the digestive juices in the acrosome when they come into touch with the oocyte (the acrosomal reaction).

Melting, runoff, and precipitation are examples of natural processes that can eventually result in the snow on top of the mountain becoming water in the ocean.
2. Describe how natural processes can cause some of the water in the ocean to someday fall as rain or snow on the mountains.
Evaporation, condensation, and precipitation are natural processes that can eventually result in some of the ocean's water falling as rain or snow on mountains. Ocean water can evaporate into the atmosphere, where it cools, condenses, and forms clouds.
How do natural processes work?The various physical, chemical, and biological phenomena that take place in the natural world without the intervention of humans are referred to as natural processes. The Earth's environment is shaped and altered by these processes, which include many others like erosion, weathering, plate tectonics, ocean currents, and the water cycle.
The mountain's melting snow creates streams and rivers that descend the mountain and into the ocean. The term for this process is runoff. In addition, the melted snow may also fall as rain and contribute to the ocean's water supply.
Rain or snow form when the clouds reach the mountains and release water as precipitation. The water cycle is a continuous process that enables water to transition through a variety of forms and locations on Earth.

Non disjunction is a genetic error that occurs during meiosis, the process of cell division that produces sperm and egg cells. There are two types of meiosis: Meiosis I and Meiosis II. Here are the possible results of a nondisjunction event in each type of meiosis:
What are the possible results of a nondisjunction event?Meiosis I:Chromosomes fail to separate properly, resulting in one cell with an extra chromosome and another cell with a missing chromosome. This can lead to conditions such as Down Syndrome (extra chromosome 21) or Turner Syndrome (missing chromosome X).A cell may end up with an extra set of chromosomes, resulting in a condition known as trisomy. Meiosis II:Chromosomes fail to separate properly, resulting in one sperm or egg cell with an extra chromosome and another sperm or egg cell with a missing chromosome. This can lead to a fertilized egg with an extra or missing chromosome, leading to conditions such as Down Syndrome or Turner Syndrome.Nondisjunction in Either Meiosis I or Meiosis II:Chromosomes may end up in the wrong cell, leading to a condition known as translocation.Chromosomes may break and reattach in a different place, leading to a condition known as inversion.It is important to note that while these errors in meiosis can lead to genetic disorders, they can also occur without any noticeable effects.

you're studying mn blood type (determined by one gene with two alleles) in hopi native americans, and you get the following genotype counts: mm: 33 mn: 62 nn: 23 based on these numbers, are the hopi at hardy-weinberg for this blood group gene? if they differ from hardy-weinberg, interpret the cause of the deviation. (if individual genotype frequencies are all within 0.05 of expectations, consider that to be not different; if individual genotype frequencies differ by more than 0.05 from expectations, then consider that to be different)
Based on the number of MN blood group genotypes, they are not from the HW data, possibly due to the Wahlund effect of interbreeding with neighboring tribes (or maybe inbreeding)
In population genetics, the Wahlund effect is the buildup of heterozygosity (ie when an organism has two different alleles at a locus) in a population caused by the structure of subpopulations. That is, if two or more subpopulations are in Hardy-Weinberg equilibrium but have different allele frequencies, the overall heterozygosity is less than if the entire population is in equilibrium. The underlying cause of this population subdivision could be a bottleneck to the geographic flow of genes followed by genetic shifts within the subpopulation.
Genotype frequency:
MM (p2) = 400/2000 = 0.2
MN(2pq) = 1200/2000 = 0.6
NN (q2) = 400/2000 = 0.2
Allele frequency:
Frequency M = p = p² + 1/2 (2pq) = 0.2 + 1/2 (0.6) = 0.2 + 0.3 = 0.5
Frequency N = q = 1-0.5 = 0.5.
Expected genotype frequencies (assuming Hardy-Weinberg):
MM (p²) = (0.5)² = 0.25
MN (2pq) = 2(0.5)(0.5) = 0.5
NN (q²) = (0.5)² = 0.25
Expected number of individuals from each genotype:
MM = 0.25 X 400 = 100
MN = 0.5 X 1200 = 600
NN = 0.25 X 400 = 100
CHI-SQUARE (X²):
X² = Σ(O-E)²/E
X² = (400-100)²/400 + (1200-600)²/1200 + (400-100)²/40
X² =225 + 180 + 200
X² =630
X² (Calculated) > X² (table), then reject the null hypothesis. Not on HWE.
Therefore, conclude there is a statistically significant difference between what was observed and what was expected under Hardy-Weinberg. That is, the null hypothesis is rejected and concludes that the population is not in HWE. They don't, possibly due to the Wahlund effect of interbreeding with neighboring tribes (or possibly inbreeding).

An increase in extracellular K+ would depolarize a neuron. This depolarization would occur if neurons were damaged. From what you have just learned about generating an action potential, what effect would this have on nearby axons? The nearby axonal membranes will ___________.
A rise in extracellular K+ depolarizes a neuron. If neurons were damaged, this depolarization would occur. The nearby axonal membranes will also depolarize.
This is because an increase in extracellular potassium (K+) ions causes the membrane potential of a neuron to become more positive, which is called depolarization. If a neuron becomes depolarized, this change in membrane potential can spread to nearby axons via the process of electrical signaling called an action potential. When an action potential is generated in an axon, the electrical charge on the membrane changes rapidly and propagates along the length of the axon. This causes the membrane potential of the neighboring axons to also become more positive, leading to depolarization of these axons as well.

How and what data could you arrange in a graph. (example, I could make a pie graph with this data)
Analyze a graph and explain some conclusion(s). (example, this bar graph showers fewer people will ____________
Answer: Whether a graph is the appropriate type for the data being presented depends on the nature and structure of the data, as well as the type of information that needs to be conveyed. For example, a line graph is often used to show trends over time, while a pie chart is used to show proportions of different categories. If a line graph was used to present data that would be better represented by a pie chart, it may not be the most effective way to convey the information.
Mistakes in the way a graph is set up can include things like using inconsistent or unequal units on the x-axis, failing to label axes or data points, and not providing a key or legend to explain the meaning of the data. These mistakes can make it difficult for the viewer to understand the information presented in the graph.
To create a graph, you would need to organize and arrange data in a way that is appropriate for the type of graph you want to create. For example, if you wanted to create a pie chart, you would need to have data that can be divided into categories, and you would need to calculate the proportions of each category.
Analyzing a graph involves interpreting the data presented in the graph and making conclusions about the information it conveys. For example, if a bar graph shows fewer people will participate in an event, one could conclude that there is a lack of interest in that event. Additionally, you can compare different sets of data presented in the graph, looking for patterns, trends and outliers.
A species of beetle can be either black or brown in color. The beetle's color is determined by a single gene, and black is recessive to brown. If changes in the environment put the brown beetles at a disadvantage for survival, which of the following will most likely occur? (R)
If changes in the environment put the brown beetles at a disadvantage for survival, it is most likely that the frequency of the black allele in the species population will increase.
The color of the beetle is determined by a single gene, with the black allele being recessive to the brown allele. When the environment changes and the brown beetles have a lower survival rate, brown beetles will be less likely to reproduce and pass on their allele. Black beetles, however, will have a survival advantage and will be more likely to reproduce and pass on their allele. Over time, the frequency of the black allele in the species population will increase, resulting in more black beetles and fewer brown beetles. This process is known as natural selection.

photorespiration is a phenomenon in which the rubisco enzyme binds to o2 rather than co2 and produces a useless 2-carbon product, which then exits the chloroplast and re-splits, producing co2. this seemingly counterproductive phenomenon is particularly problematic for the plant becausec
In photosynthetic organisms, a metabolic pathway known as photorespiration takes place. It results in the release of carbon dioxide, the consumption of oxygen, and the absence of chemical energy or food. The rate of plant growth is constrained by this process.
How does photorespiration affect the enzyme RuBisCO?RuBP binds to O2 in the photorespiration pathway to produce PGA (3C chemical) and phosphoglycolate, one molecule at a time (2C compound). Both the synthesis of sugar and ATP is absent. Instead, the usage of ATP causes CO2 to be released into the atmosphere. The reduction in stationary CO2 emissions is 25%.
What makes photorespiration an inefficient reaction?Photorespiration is widely seen as a wasteful process since it oxidizes organic carbon without clearly producing ATP and creates 2PG, a substance that is "toxic" to many enzymes in photosynthetic metabolism.

A wave in which the motion of the medium is parallel to the direction
of the wave is called a (an)
Answer: Longitudinal wave
Explanation: waves can be categorized on the basis of direction of movement of the individual particle of the medium relative to the direction of the wave it travels. Now, on the same basis we will categorize longitudinal and transverse wave.
Now the question asked about the longitudinal wave so, we can answer through the following definition. stationary waves are the waves which remain stationary with respect to time and distance.
longitudinal waves are the waves in which the vibration of the medium is parallel to the direction the wave travels and displacement of the medium is in the same direction of the wave propagation.
the lungs deliver a regular supply of oxygen to the blood, which is in turn circulated to most of the cells of the body. at the same, time oxygen is consumed during aerobic cellular respiration within these cells. this implies that . the lungs deliver a regular supply of oxygen to the blood, which is in turn circulated to most of the cells of the body. at the same, time oxygen is consumed during aerobic cellular respiration within these cells. this implies that . the concentration of oxygen is higher inside of the cell relative to outside of the cell oxygen requires active transport to enter most cells the rate of oxygen diffusion is independent of concentration oxygen will passively diffuse into the cells
The lungs deliver oxygen to the blood and oxygen is consumed during aerobic cellular respiration. The concentration of oxygen inside the cell is higher than outside, so oxygen needs to be actively transported into the cells. The rate of oxygen diffusion is dependent on the concentration gradient, and oxygen will diffuse across the cell membrane from an area of higher concentration to an area of lower concentration.
How does lungs supply oxygen to the blood?The lungs deliver a regular supply of oxygen to the blood, which is in turn circulated to most of the cells of the body. At the same time oxygen is consumed during aerobic cellular respiration within these cells. This implies that:
1. The concentration of oxygen is higher inside of the cell relative to outside of the cell - This is because oxygen is used up in the cells during respiration, and the blood carries a regular supply of fresh oxygen to replenish the cells. Therefore, the concentration of oxygen will be higher inside the cells than outside.
2. Oxygen requires active transport to enter most cells - This is because the concentration of oxygen is higher inside of the cell than outside, and oxygen therefore needs to be actively transported into the cells.
3. The rate of oxygen diffusion is independent of concentration - This is not true. The rate of oxygen diffusion is dependent on the concentration gradient - the higher the gradient, the faster the rate of diffusion.
4. Oxygen will passively diffuse into the cells from the surrounding environment - This is true. Oxygen will diffuse across the cell membrane from an area of higher concentration to an area of lower concentration.

macconkey agar without crystal violet is a culture medium useful in the presumptive identification of: ____
A culture media helpful in the gram-negative bacteria's presumptive identification is MacConkey agar without crystal violet.
In the Gram staining method of bacterial differentiation, gram-negative bacteria are defined as those that do not maintain the crystal violet stain. [1] They are distinguished by having cell envelopes made of a peptidoglycan cell wall sandwiched between a bacterial outer membrane and an inner cytoplasmic cell membrane. Almost every environment on Earth that supports life contains gram-negative bacteria. The Escherichia coli model organism is a gram-negative bacterium, as are many pathogenic bacteria including Pseudomonas aeruginosa, Chlamydia trachomatis, and Yersinia pestis. They provide a serious medical issue since their outer membrane shields them from a variety of medications, including penicillin, detergents that would typically disrupt the inner cell membrane, and lysozyme, an antibacterial enzyme generated by mammals that is a part of the innate immune system.
