Water Cycle is the answer
Mitochondria provides energy for moving chromosomes
This question is incomplete. The options are:
<span>a. be choosy about which females they mate with.
b. be indiscriminant about which females they mate with.
c. mate with as many females as possible.
d. compete to mate with choosy females.
</span>
The answer is a: be choosy about which females they mate with.
This is because the male would in this case be investing a lot of energy in parenting its young, and would therefore adopt a strategy of mating with one or very few females. It therefore makes sense that the male would be choosy in regards to its mate.
Answer:
Carcinogenic
Explanation:
A carcinogenic substance is able to modify or damage the genome in a way which promotes the formation of cancerous cells. Cell cycle checkpoint proteins are very crucial for the progression of normal cell cycle. They check for any anomaly in their designated step and halt the process if it is detected. Repair mechanism is activated and cell cycle does not progress till the damage has been repaired.
Here, the pollutant alters the structure of these proteins such that they lose their function. They are not be able to stop cell cycle from progressing even if there is some damage in the genome. The cell divides and gives rise to more damaged cells. Eventually these cells lose their normal function and just keep dividing due to which their division rate becomes double of the normal rate. It can ultimately give rise to cancer which is why the chemical is carcinogenic.
