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.
The correct answer is A. Apical meristem
Explanation:
In plants, the primary growth refers to the type of growth that increases the length of the stem or toots in opposition to the secondary growth in which the stem thickens and that occurs as the result of the vascular cambium. However, in the case of primary growth, this can be explained mainly due to the action of apical meristem that is a type of tissue located in the tips of roots and the stem and therefore the type of tissue in which the growth takes place mainly through cell division. Considering this, it can be concluded primary growth is due to the action of the apical meristem.
One of the changes in development and specialization that did not happen in primitive mammals was the increase in stomach capacity. The specialization of teeth and the lower jaw are two important modifications of the primitive mammals. Also an increase in size and brain capacity are two crucial modifications of the early mammals.
