Occasionally cells stop dividing and enter another phase, G. If you damage your liver, new
liver cells can be produced to replace up to 75% of the liver. However, if you sustain brain
damage, your body does not produce new brain cells. Explain this observation using what
you have learned about the cell cycle. Hint: What phase of the cell cycle are the brain cells
in once they mature?

Answers

Answer 1

The  phase of the cell cycle are the brain cells in once they mature is G0 phase (inactive phase).

What happens in the G0 period?

The G₀ phase is the phase of the cell cycle where the cell remains in interphase indefinitely. Generally, highly specialized cells such as nerve cells are found in G0. Depending on the type of cell, stimulation and the return of the cell cycle can occur.

It is important to mention that there are cells that do not divide and that, for this reason, do not pass to the later phase, S. When this happens, the cell remains in a phase called G0.

These cells that do not divide further exist G1 phase to enter an inactive stage called quiescent stage (G0) of the cell cycle.

In the Old field mice example scientists found variation in fur color ranging from light to dark brown. One might think they are not the same species because they are so different in appearance. But the early scientists actually brought live mice to the lab, some with dark fur, some with light, and found that he could successfully breed them in the lab, suggesting that were the same species. What species concept best applies to this situation.

Answers

Answer:

Specie is a group of organisms that can interbreed with one another and produce fertile offspring.

Explanation:

Species Concept that applies to this situation is that a specie is a group of organisms that can interbreed with one another and produce fertile offspring. According to the example of mice, we can conclude that species having different appearance if belongs to the same group so it can interbreed with one another and produce offspring which is fertile and continue its generation.

Approximately 75% of the Earth's surface is covered in water. Why is water considered such a precious resource?

Answers

Answer:

Water is precious since it is one of the most basic commodities that sustain the life of human beings, animals and plant. Without water, it would be impossible for any form of life to exist in the universe. Close to 75% of the Earth is covered with salt water, while 2% of the surface contains frozen water.

Explanation:

Why is water a precious resource?

It is needed for all living things and must be managed well to ensure we have enough for our needs and to protect our environment. Water is a precious resource. We can't live without it. Clouds formed by this vapor ensure that water falls back down to Earth as rain, sleet, snow or hail.Water resources are sources of water that are useful or potentially useful to humans. It is important because it is needed for life to exist. Many uses of water include agricultural, industrial, household, recreational and environmental activities. Virtually all of these human uses require fresh water.

A process that involves the transfer of energy from one location to another is a convection current. It is also known as heat transfer by convection.

Convection currents are fluid movements brought on by temperature or density variations within a substance. Because the particles within a solid are fixed in place, convection currents are only visible in gases and liquids. A straightforward illustration of convection currents is warm air rising toward a home's ceiling or attic.

A) Does crossing-over generate more genetic diversity than the fusion of gametes does?

B) Does DNA methylation prevent independent assortment during metaphase II?

C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?

D) Do daughter cells that are not genetically identical to parent cells produce viable zygotes?

Answers

The answer is C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?

C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?

What is independent assortment?

Independent assortment is a mechanism that contributes to genetic diversity during meiosis. It refers to the random alignment and separation of homologous chromosomes during the first meiotic division (meiosis I), which leads to different combinations of chromosomes being passed on to the daughter cells.

This means that each daughter cell will have a unique combination of chromosomes. When the gametes (sperm or egg cells) produced by meiosis fuse during fertilization, they can give rise to offspring with a unique combination of genetic information, further increasing genetic diversity within a population.
