Answer:
D
Explanation:
A is not correct as the lighter mouse are more visible, and are more likely to die. They can't reach reproductive age if dead.
B is not correct because lighter mice cannot be successful in finding food if easy prey for predators.
C is not correct because the question shows the predator being the variable that changed the population of lighter mice, not food.

List down the major actions that lead daughter cells to be different from parents cells meiosis?
Answer:
The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
Explanation:
Select the opposite strand to the following DNA sequence: ATG - CCC - CGA
1)AAG - CCC - GCT
2)GCT - GGG - CAT
3)TAC - GGG - GCT
Answer:
Option 3: TAC-GGG-GCT
Explanation:
Remember that A=T and C=G. Wherever there is an A, switch it with a T, and wherever there is a C, switch it with a G.

A model showing two possible arrangements of chromosomes during meiosis is shown in Figure 1.Figure 1. Two possible arrangements of chromosomes during meiosis
Which of the following questions about genetic diversity could most appropriately be answered by an analysis of the model in Figure 1?
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?
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.

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

9. How do the chromosomes of a daughter cell compare to the chromosomes of a mother cell?
The daughter cells have n chromosomes. The mother cell has 2n.
The daughter cells have the same type of chromosomes, but a different number
The daughter cells are identical to the mother cell.
The daughter cells have twice as many chromosomes as the mother cell.
Answer:
The daughter cells are identical to the mother cell.
The daughter cells have twice as many chromosomes as the mother cell.
Explanation:
Daughter cells are identical means same shape and structure to the parent cells because the parent cell is divided equally and as a result daughter cells are produced. In mitosis cell division, two daughter cells are produced having double number of chromosomes just like parent cell, whereas in meiosis cell division, four daughter cells are produced having half number of chromosomes.

A kind of reproduction involving one parent animal
A kind of reproduction involving one parent animal is called asexual reproduction, as there is no crossing of the genes and, due to the absence of sexual reproduction, the single parent is involved.
What is the significance of the offspring of asexual reproduction?Asexual reproduction is a kind of reproduction where there is no need for the involvement of the two parents, such as in sexual reproduction, where there is the involvement of one male and one female, but this is absent in asexual reproduction. Asexual reproduction leads to the formation of identical offspring without any uniqueness.
Hence, a kind of reproduction involving one parent animal is called asexual reproduction, as there is no crossing of the genes and, due to the absence of sexual reproduction, the single parent is involved.

The circled portion of DNA labeled X in the following picture is a
a phosphate group
b sugar
c nucleotide
d aldehyde base
Answer:
a. Phosphate group
Explanation:
The circled portion of the DNA labeled X is ; ( C ) Nucleotide
The Nucleotide in a DNA molecule is the building block of the nucleic acid and it consists of a sugar molecule, A phosphate group ( P ) and nitrogenous base like adenine, cytosine or guanine.
The circled portion covers a nitrogenous base ( cytosine ), a phosphate group and a sugar molecule therefore the circled portion correctly represents a Nucleotide in a DNA molecule.
Hence we can conclude that the circled portion of the DNA is Nucleotide.

plant breath through
Answer:
Plants respire through plant pores, called stomata. During respiration and photosynthesis, gases go in and out of the plants through stomata using diffusion, not breathing.
Answer:
respiration
Explanation:
Plants breathe through a process called respiration, where they exchange gases between the outside and the inside of their bodies as a living organism. They breathe through openings called stomata. Photosynthesis makes a plant produce oxygen, but a plant also requires oxygen constantly.
