Answer:
The correct option is A. The genetic variation introduced during recombination provides new allelic combinations for natural selection to act upon.
Explanation:
Recombination will lead to more possibilities for allelic combinations. This will result in increase in the number of genetic variations for a population.. The genetic variations in a population help the organisms to better adapt to different environmental conditions. If genetic variation is low for a population, then there are more chances for the population to become extinct or endangered when disasters occur. Many ecologists blame lack of genetic variation for extinction of different species.
Answer:
The incorrect statement is -C. They are ALL parasites that harm their host by living in or on it.
Explanation:
Protists are organism shows the vast difference and have a single cell microscopic eukaryotic cell. These are based on their characteristics similar to plants or animals divide them into two groups called plant-like protists and animal-like protists.
Animal-like protists are also a eukaryotic unicellular organism that depends on other organisms for their food so they are called heterotrophs. Some of these organisms also parasites and affect their host negatively. These are also organisms that are live symbiosis and help other organisms.
Mountains are formed in the lithosphere. Litosphere is the solid shell of the planet Earth, which <span>includes the brittle upper portion of the mantle and the crust.

They usually live alone, when not breeding.
