Answer:
It could lead to several later problems in the cell.
Explanation:
Removing a piece of DNA could severely affect the cell but it could also cause nothing. Depending on the part that is damaged, it could codify for a vital protein but it could also be an intron, which are pieces of DNA that don't codify for any protein. This has been recently researched and even though there are introns that could cause some serious trouble, most of them are an unknown matter to nowadays scientists. Anyway, a wrongly repaired sequence could end in a mutation that can potentially damage the cell and therefore the organism.
The correct answer is A. maintaining homeostasis.
Homeostasis is a term referring to an organisms continuous process of maintaining and auto-regulating the conditions of its internal environment. Variables such as pH, temperature, and fluid balance need to be at optimal conditions in order for the organism to function properly.
In this example, the phosphate buffer system permits the organisms to maintain a constant pH in their intracellular fluid. This is one of the organism's homeostatic mechanisms.
Plants take in nitrogen from the soil by absorption. So option B.

Answer:
The other populations will decrease.
Explanation:
If the grass population decreases, then the grasshoper population will decreace, causing the mice population to decrease, which will lead to the decrease in owl population.
