Answer:
a) Absorption is important since body needs energy from nutrients, therefore this process must be done inoder for energy to be produced by the process of respiration.
b) Digestion must take place because those nutrients taken in have to be in smaller molecules for the absorption to be succeful.
a) Assimilate is the utilization of nutrients into the body cell. it's the process where by macromolecules are synthesized from the absorbed simple molecules.
b) After assimilation process growth and repairment occurs within the cell. It's purpose is to build up the cell for to function well.
<span>While alien genomes may be constructed by completely different molecules (for example, silicon based life forms are a possibility rather than carbon) it is logical to assume that all life forms would have some sort of protective mechanism to prevent the degradation of DNA during replication. Essentially, to prevent mutations and rapid aging, DNA, alien or otherwise, would have some types of telomeres. They might either be long chains of repeated or irrelevant code or molecules that would not be easily corrupted.</span>
Evolution :).
Descent with modification helps to explain anatomical similarities among certain species. The bones of the forelimbs of humans, cats, and bats (you can add in penguins, alligators, and more) are used in different ways but have similar structures.
The best explanation is that these animals have a common ancestor. With new generations, new species emerged by natural selection from different populations, and with this, the bones become better for different tasks.
The forelimbs and other such structures with anatomical similarities due to a common ancestor are called homologous structures.
Striped, one nucleus and smaller than skeletal muscles.
Hope this helps, God bless <3
Answer:
b
Explanation:
this is because Invasive species are frequently generalists in terms of food, or habitat needs, have fewer predators in their introduced environments and are better able to exploit disturbances than their native competitors.
