Answer:
The correct answer would be an option B.
Asexual reproduction is a reproduction in which offspring are produced from a single parent.
It does not involve fusion of gametes and crossing over due to which the offspring contain identical genome as that of parents.
This reduces the genetic diversity in a population due to which all the organisms of a population are at equal risk of extinction under unfavorable conditions such as high temperature, antibiotics, change in pH of surrounding medium et cetera.
Thus, the disadvantage of asexual reproduction is the lack of genetic diversity due to which a single antibiotic is able to kill millions of genetically identical bacteria.
Answer:
If an organism has a beneficial trait, they have a higher chance of survival, and if they can survive they can reproduce too.
Example: Speckled moths camouflage with the bark of trees and are not easily seen by predators. Black moths do not camouflage with the bark of trees and are easily seen by predators, therefore the black moths are eaten. Because the black moths have been eaten they cannot reproduce and pass on the trait for black wings to their offspring, but the speckled moths are able to reproduce because they survived and are able to pass on the speckled wing trait to their offspring.
Answer:
Strong hydrologic connections among terrestrial and inland aquatic realms exist in both river floodplains and dryland ecosystems. In the evolution of river floodplains terrestrial vegetation diversifies inland aquatic habitats, providing a range of colonization options for different organisms
