Answer:
c.cellulose
Explanation:
it makes the cell walls of the plant cells whuch is abscent in animal cell.
The cell that is the precursor of all types of blood formed elements is the Hemocytoblast. The formed elements of blood, through the process of hemopoiesis, they are continually produced, replacing the relatively short-lived erythrocytes , leukocytes, and platelets. The process starts in the red bone marrow, with the hemopoietic stem cells that differentiate into myeloid and lymphoid lineages.
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.

The function of scientific research in solving issues of human health differs on the basis of what field one is studying. As it can aim at the diagnosis, causes, or treatments of the condition.
If one is looking at the causes, science will assist in focusing on what the issue actually is. At the same time, science can also assist to find the best treatments. Once one can find a cause, one can even figure out the best treatment for it.
There was a time when we were very physically active, but now we rely on devices to do most of our work. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species.
