The correct answer is coevolution.
The term is used to illustrate the conditions where two or more species communally influence each other’s evolution. For example, an evolutionary modification in the morphology of a plant may influence the morphology of a herbivore that consumes it, this, in turn, may influence the evolution of the plant that might influence the evolution of the herbivore and so on.
Coevolution most possibly takes place when distinct species have a close ecological association with each other. These ecological associations include parasite/host and predator/prey, mutualistic species, and competitive species.
Answer:
The phenomenon of unequal separation in meiosis is called nondisjunction. If nondisjunction causes a missing chromosome in a haploid gamete, the diploid zygote it forms with another gamete will contain only one copy of that chromosome from the other parent, a condition known as monosomy. I think sorry if wrong ;)
The correct answer is "C".
Onion cell is a plant cell and human cheek cell is an animal cell. Hence, onion cell has a cell wall<span> but not in human cheek cells because animal cells do not have cell wall. Both cells have single nucleus. Since, human cheek cell is an animal cell, chloroplasts are cannot be seen in the human cheek cells.</span>
These had no leaves or roots, instead they had green photosynthetic stems which served as both anchors in the ground and photosynthetic surface.
