Answer:

a. 1/2 b. The organism is an animal

Explanation:

a. What is the medullary index for an organism that has a medulla width of 2cm and hair shaft width 4cm?

Medullary index = diameter of medulla/diameter of hair.

Given that diameter of medulla = medulla width = 2cm and diameter of hair = hair shaft width = 4cm,

Medullary index = diameter of medulla/diameter of hair = 2 cm/4cm = 1/2

b. Is this organism human or animal?

Since the medullary index = 1/2 > 1/3 (if it is ≤ 1/3 it is human hair and ≥ 1/2 it is animal hair), it is animal hair. So, the organism is an animal.

Answer:

The depolarization of the ___SOMA NEURONAL_________ normally generates the action potential that leads to the depolarization of all other cells of the heart muscle.

Explanation:

The depolarization of the neuronal body, that is, the body of the neuron, generates an action potential that is transported throughout the axon, until in the motor unit (union between neuron and muscle) the action potential is transmitted to the cardiac cell, depolarizing the membrane of the myocardial cell and thus effecting cardiac contraction.

Cardiac contraction occurs in a controlled, rhythmic and systematic manner, with autonomic character and as a consequence of the release of calcium from REL to LIC

How do cells monitor DNA integrity?Cells monitor DNA integrity through check point processes that monitor the structure of the DNA as the cell cycle progresses.What went wrong with Henrietta Lacks’s cells?Henrietta’s cervical cells were infected with human papilloma virus, which mutated the DNA and made the cells cancerous.How does infection with human papillomavirus increase the risk of cervical cancer?Infection from human papilloma virus mutates the DNA of the cervical cells. Mutated cells increase the risk of those cells becoming cancerous.Philadelphia Karyotype. How do cells monitor DNA integrity?Cells monitor DNA integrity through check point processes that monitor the structure of the DNA as the cell cycle progresses.How are the chromosomes different in the cancer cells compared to normal cells?Chromosomes in cancer cells differ from those in normal cells because they usually have a larger

Chromosomes of cancer cells are often damaged mutated or missing parts, thus making them different from normal cells.How could these lead to different types of cancers?This can lead to different types of cancer, because when the genes replicate and cross over, the mutated genes are transferring. This can lead to ill functioning cells that lead to cancer.Essays Some types of cancer result from changes to individual genes, whereas others result from chromosome-level changes to the genome. Which of these types of cancer would you be able to detect by karyotype and why? Both would able to be detected by a karyotype.Because genes are on the chromosomes, when the individual genes are changed, it alters the appearance of the chromosome, which can be detected by a karyotype.When looking at the genome, one can see all the chromosomes making up the organism. If there was an alteration with the chromosomes, the karyotype would detect it. Karyotypes can be used to identify mutations in different forms of cancer, as you have seen in the HeLa and Philadelphia karyotypes. However, they are also useful in detecting other genetic abnormalities, such as Down syndrome. What would a karyotype of an individual with Down Syndrome look like, and what

would that provide to a geneticist? A karyotype for an individual with down syndrome would have an extra copy of a chromosome. This would help geneticists can view the abnormalities in the chromosomes, and help find out how that abnormality was caused.

Answer:

Because they might be taking in a higher concentration of the toxin through food or their environment or others could just be older meaning theyve ingested more of the toxin overtime

Explanation:

The level of toxin in fishes that lives in the area of the same pollution may differ due to the ability to consume toxins.

Toxins may be defined as a poisonous substance that is a specific product of the metabolic activities of a living organism and is usually very unstable, notably toxic when introduced into the tissues, and typically capable of inducing antibody formation.

While living in the area or habitat of the same pollution, still some fishes have more of this toxin than others. This is because these fishes have the ability to consume toxins from food resources that are present in the same habitat. While some fishes consume high toxins, but in results, they do not have the ability to resist in the high level of toxins, so they get eliminated or died.

Therefore, the level of toxin in fishes that lives in the area of the same pollution may differ due to the ability to consume toxins.

Answer:

a. Developing cells may express different parts of their identical genetic instructions.

Explanation:

Humans are multicellular organisms i.e. we possess many cells in our body. These cells increase as a result of division. Although all of the cells of humans develop from one fertilized egg (zygote), the human is born with many different types of cells because of a process called CELL DIFFERENTIATION.

Cell differentiation is a process in multicellular organisms where a cell becomes more specialized in function as it divides. The set of genes contained in each cell are not expressed simultaneously i.e. some genes are expressed while others are repressed. This is how cells with the same gene possess different functions. Therefore, according to this question, developing cells may express different parts of their identical genetic instructions to be of different types.

Clean energy are renewable energy. This are energy from natural sources that are renewed without extra cost. Sun, wind, water are examples of renewable natural resources that helps generate clean energy.

The energy are refer to as clean because, they do not lead to any deposit of gasses that can affect the environment leading to environmental pollution. They have little or no side effects, no combustions or release of gases that are toxic or can deplete the environment as in the case of non- renewable energy.

Pinocytosis and phagocytosis are examples of active transport that cells use to maintain homeostasis, hence option A and C are correct.

The propensity to oppose change in order to preserve a stable, largely constant internal environment is known as homeostasis. Negative feedback loops are frequently used in homeostasis to combat deviations from set positions in a variety of properties.

Moving uphill is considered active transportation. A cell must expend energy to transport materials against a concentration or electrochemical gradient.

This is precisely what active transport systems do they use energy, frequently in the form of ATP, to keep the proper concentrations of ions and molecules in living cells.

Therefore, option A and C are correct.

Green

Explanation:

Answer:

Process of seeping (flow or leak slowly through a porous material or small holes) of water into the ground is called infiltration. Infiltration is the process by which water on the ground surface enters the soil.

Water not used by plants moves deeper into the ground. The top of the water in the soil, sand, or rocks is called the water table and the water that fills the empty spaces and cracks is called groundwater. Water seeping down from the land surface adds to the groundwater and is called recharge water.

Hence The process of water seepage into the ground is called Infiltration.

Biogeochemical cycles are the various cycles that essential for the living organism. In these cycles, elements or compounds are moved between living and nonliving organisms. These cycles are interconnected to support life and move the energy and molecules into the loop. Examples of such biogeochemical cycles are the water cycle, carbon cycle oxygen cycle, and many others.

Carbon is an element that is important and moves in different spheres of earth including the atmosphere, geosphere, and biosphere. Similarly, water is a compound essential for living organisms and moves from the hydrosphere to living organisms and the atmosphere.

Answer:

They will evolve into a new species

Explanation:

The most likely result from this scenario is that the now isolated group of beetles will evolve and become a new beetle species that is unique from the old population.

The beetles have become geographically isolated from the original population and this makes them become a new species through the process of allopatric speciation. Allopatric speciation is an evolutionary mechanism of species formation as a result of being geographically separated from the old population. It is as opposed to sympatric speciation in which a new species is formed within a population of species without being geographically barred from the original population.

The fact that the isolated species are now in an environment that is different from that of the original population means that they will take a different route to evolve in terms of trying to adapt to the changes that would be occurring in their environment.

unipotent stem cell

Explanation:

Answer:fertilization

Explanation:

Answer: Sexual reproduction occurs in three stages: pollination, fertilization, and dispersal. During pollination, pollen is transferred from the anther to the stigma. Once the pollen is stuck to the stigma, it produces a pollen tube that grows down the style to the ovary and into the ovule. A sperm cell then travels down the pollen tube into the ovule and fertilizes the egg cell. The fertilized egg is called a zygote. This zygote grows into a plant embryo. The embryo is located inside the seed along with the seed coat and stored food. The ovule develops into the seed. The ovary develops into the fruit that protects the seed. The fruit also helps disperse the seed. Seeds are dispersed, or spread, to new locations, where they grow into seedlings.  or pollen is taken to the stigma. i took the test

Explanation:

Answer and Explanation:

Cells directed their growth by getting the signals from distant or local bases and respond by directing signals. Each signal changes the cell state and decides how cells reply to consequent signals. RTK (receptor tyrosine kinase) signaling is needed for the arrangement of the R1-R7 photoreceptors. It activates the phyllopod transcription through the Ras/MAPK pathway. The Phyllopod transcription codes an adapter protein that guides the ubiquitin ligase Sina to target the transcription factor named Ttk (tram track) for deprivation.  Tram track (Ttk) is the main inhibitor of the development of photoreceptors. The cells that do not damage Ttk become the ommatidium components, while those cells that damage it continues to develop photoreceptors. Receptor tyrosine kinase signaling is also involved in the development of ommatidium. Receptor tyrosine kinase signaling controls the propagation and existence of cells before they are employed in the cluster. RTK also regulates the differentiation of cone cells. Whether a cell becomes a photoreceptor or not is also decided by RTK signaling events.

Answer:

D. Different parts of the molecule have slightly different charges

Explanation:

Water is a polar molecule because different areas of the molecule have different and opposite charges

Oxygen has a higher electronegativity than hydrogen, which means the electrons of the water molecule will stay closer to the oxygen than the hydrogen.

This creates an uneven distribution where the oxygen has a partial negative charge and the hydrogen has a partial positive charge.

So, D is the correct answer.
