The correct answer is option D, It needs sunlight to survive.
Reason -
Phytoplanktons are the plant species of planktons and thus they need sunlight like all green plants to survive and produce food. The sun light is predominantly available at the ocean’s surface, thus the phytoplanktons occur near the surface of ocean. Along with sunglight , phytoplanktons also need water, nutrients and CO2 to grow which are readily available at the ocean’s surface.
I think it might be protein bc everyone needs protein
It is called Fluid Mosaic Model. It describes the structure of the plasma membrane as a mosaic component. The structures such as phospholipids, protein, carbohydrates and cholesterol gives the fluid like character of the plasma membrane.
Mitochondrial DNA mutation occurs at a constant rate throughout history. Thus, each different base in Mitochondrial DNA is able to show just how long ago the 2 species diverged from each other.
Hope this helps! :)
