Its is D because asexual reproduction is done by plants. Pollination is the process that transfers of pollen grains from the anther to the stigma.
Answer: Proteomics, generally regarded as the comprehensive study of the expression of all the proteins at a particular time in different organs, tissues, and cell types is a key enabling technology for the systems biology approach.

Explanation:
Some aphids make black walnut trees their habitat in the forest and only prefer to mate with aphids who have the same habitat. This is an example of reproductive isolation since these aphids now have different mating preferences and hence are isolated from rest of the aphids. The isolation occurred on the basis of difference in habitats so it is also an example of habitat isolation. Since the mating is prevented all together it is also an example of prezygotic barrier i.e. formation of zygote is inhibited. However, it is not an example of allopatric speciation since the aphids are not separated geographically from each other. They are present in the same area but have different habitat preference. Hence, option C is correct answer.

The proof that cells only come from other cells
He proved it by his "swan-necked flasks" in which nothing formed in sealed flask whereas many organisms were there in open flask.
So, in short, option D is your final answer!

Answer:
viral envelope
The phospholipids in the viral envelope are similar to those in the plasma membrane of an infected host cell. The viral envelope is, in fact, derived by budding from that membrane, but contains mainly viral glycoproteins.
