Agricultural chemicals is an example of a nonpit source of freshwater pollution
Answer:
Primates
Explanation:
Humans are primates a diverse group that includes some 200 species. Because primates are related, they are genetically similar. Human DNA is, on average, 96% identical to the DNA of our most distant primate relatives, and nearly 99% identical to our closest relatives, chimpanzees and bonobos.
<span>Naturally occurring in both humans and bacteria and functions in DNA replication. The process of DNA Replication is extremely complex. Especially in humans, and needs specific molecules, like ligase, to be done. This molecule can be found in other species too.</span>
A/Cell membranes and cell walls are selectively permeable and aid in communication.
Explanation:
Cell Membranes or cell wall have phospholipid bi layer which functions
as a selectively permeable barrier that separates an internal
environment from an external one. They are selective permeable through
passive process (concentration gradient) allowing certain molecule
diffuse into cells
