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).

Sodium-glucose coupled transporters transfer sodium ions and glucose symportantly (in the same direction). A facilitated diffusion mechanism is used by the GLUTs to carry glucose across the plasma membrane.

In order to transport glucose against its gradient of concentration, SGLTs must instead rely on the sodium concentration gradient produced by the sodium-potassium ATPase as a source of chemical potential in plasma membrane.. The SGLTs that absorb glucose from food sources are found on the luminal surfaces of the cells lining the small intestine. Additionally, they are present in renal tubules where they aid in the reabsorption of glucose from glomerular filtrate.

Oleg, 3, who was born in an orphanage, will be adopted by Terry and Ahmad. Terry and Ahmad should be aware that early, chronic institutionalisation causes the cerebral-cortex to shrink in size and activity.

There are a huge number of neurons in the cerebral cortex. High-order cognitive processing or the conscious mind is carried out by these neurons in humans. The sensory signals produced by the body are terminated in the cerebral cortex. These sensory inputs are further processed at various levels, and the combined information is ultimately applied to the creation of particular actions. The cerebral cortex is made up of a layer of cells and fibers that is 2 to 4 mm thick and has numerous local interconnections in order to carry out this highest grade of processing.

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.

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 karyotype is the complete set of chromosomes of an organism, arranged and displayed in pairs and ordered by size. It is used to identify chromosomal abnormalities and to study the genetic makeup of an organism. The karyotype can be visualized through a microscope after staining the chromosomes to make them visible. It is a powerful tool in genetics, as it can be used to identify specific chromosomal disorders and to study the genetic makeup of an organism.

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.

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.

Organisms on each island have adapted to the unique conditions of that island.

Organisms on remote islands are somewhat similar to one another, indicating common descent.

Both Darwin and Wallace recognized that if an animal has a trait that allows it to withstand the elements or breed more successfully, it may leave more offspring than others. The trait will become more common in the next generation and the generation after that.

Evolution, according to one theory, occurs. To put it another way, organisms evolve over time. As descendants diverged from common ancestors in the past, life on Earth changed. The other theory holds that evolution occurs through natural selection.

Complete Question -

what are the two main observations that charles darwin and alfred wallace made during their expeditions? select two (2)

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.

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.

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.

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).

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.

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%.

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.
