Answer:
Ribosomes, Cell membrane
Explanation:
Ribosomes can be described as structures which are involved in the production of proteins. Ribosomes are hence known to be the protein manufacturing units of a cell. As enzymes are also proteins,they will be synthesized in the ribosomes.
Cell membrane can be described as the membrane which is present outside the cell or which separates the cell from the external environment.
For an enzyme to pass through the external environment, it will have to pass through the ribosomes and the cell membrane.
Given what we know about phytoplankton biomass peaks in the polar region of the northern hemisphere, we can confirm that this occurs in the spring.
As the polar regions are tilted away from the sun, days there are short, sometimes these regions even enter month-long periods of darkness. Due to this, sunlight is not always strong enough to penetrate deep into the water.
In the Northern Hemisphere, the phytoplankton biomass peaks in the spring given that during this time the sun is high enough in the sky for sunlight to penetrate deep into the water and provide a food source for the plankton to thrive.
