Answer:
Staining
Explanation:
In order to make cells or certain features of a cell more visible under the microscope, scientists use specific stains. These stains bind to certain features in a cell, allowing better distinction. For example, iodine is a common stain used in plant cells, as it turns blue/black in the presence of starch, which is abundant in plant cells.
We explain this puzzle-piece-like build as proof of tectonic plate shifting. As magma inside the earth moves, so do the continental plates on top of the magma. The continents used to be fused together in one larger continent called Pangea. Over the course of 1000s of years, the plates have shifted.
tldr: tectonic plate movements cause this phenomena
Answer:
The expression of the mRNA decreases.
Explanation:
The RNAi binds to some proteins forming a silencing complex. This complex binds to the target mRNA (of which the RNAi is complementary) and cleaves it (cuts it). The cell will detect the generated fragments of mRNA , recognize they are aberrant and will thus degrade them.
All in all, this mechanism silences (reduces) the expression of the mRNA, because it will be degraded instead of translated into protein.
I think the answer is D
as A would mean that the abyssopelagic organisms would be best adapted and therefore a large biomass which isn't the case and it isn't B nor C so it must be D
Hope that helps
