Explanation:
2 answer
Answer: B, W, E, Q, K
Explanation:
b.a higher surface area/volume ratio than the parent cell
c. more DNA in its nucleus than the parent cell
d.less DNA in its nucleus than the parent cell
The surface area to volume ratio will be higher as compared to the parent cell after cell division. Hence, option B is correct.
Further Explanation:
Cellular division is known to be the process through which the parental cell segregates into two or more daughter cells. This process generally occurs as a segment of a larger cell cycle. It comprises of 2 main stages, interphase and M-phase. Interphase is further segregated into:
M phase or mitotic phase is the next stage after interphase and is segregated into 4 phases:
During cellular division, the cell segregates into 2 daughtercells and as the cell becomes larger, the volume elevates rapidly as compared to its surface area. Hence, option B is correct. The reduction in the cell’s ration of the volume to surface area makes it difficult for the cell to transport the required substances in and move out the waste products quickly enough for the cell to survive.

OPTION A.
After cell division, each daughter cell has a higher surface area/volume ratio than the parent cell. This is due to the division resulting in two smaller cells with same DNA content. This increased ratio is beneficial for the exchange of material across cell membrane.
After cell division, each daughter cell has a higher surface area/volume ratio than the parent cell. When a cell divides, it splits into two smaller cells, reducing the volume but not reducing the surface area in the same proportion. This results in each daughter cell having a larger surface area relative to its volume. This increased ratio is important because it allows for more efficient exchange of nutrients and waste products across the cell membrane.
The amount of DNA in each daughter cell is the same as in the parent cell because during cell division, the DNA is copied and then distributed evenly between the two resulting cells. Therefore, option c and d are incorrect.

Answer: Directional Selection.
Explanation:
This process can be defined as the positive selection in which one phenotype is selected over the other phenotype, causing the allele frequency to shift towards the other phenotype.
The allele favored by directional selection is advantageous. There is a increase in the rate of reproduction and chances of survival.
Here, the population of rabbits are decreasing in size over a period of time because they adapted the burrows to live in. Gradually small size of the rabbits were favored.
This is an example of directional selection.
Answer:
The correct answer is- Synthesis(S) phase
Explanation:
Interphase is the phase where cells spend most of their time. It is known as the resting phase and contains 3 stages called G1, S, and G2 phase. In G1 phase cells grow in size and produce those enzymes which are required for DNA replication.
In the synthesis phase, the DNA is replicated and gets doubled. This event is very important in the cell cycle because it allows each cell produced after cell division to take an equal amount of genetic material which is identical. Therefore in the cell cycle DNA replication occurs in the synthesis phase.
The opinion of scientists in a particular field with majority of them supporting a concept, belief or a suitability of a question lead to scientific consensus. The consensus may or may not be proved true at the end of the research but at their primary level they gain maximum support as they are based on some evidence or observation. Overall scientific consensus can be stated as convergence of high quality evidences leading to same conclusions.
