The primary purpose of photosynthesis is to convert solar energy into chemical energy so that the plant can store that new chemical energy away for later use.
Answer:
D). genetic drift
Explanation:
Genetic drift is the change in an allele frequency over a period of time. This event has to be random and a chance event.
For example: In a population of a flowering plant there are two types of flowers, blue and yellow. Due to a fire many yellow flowers are destroyed by chance. Now the resultant population will have more blue flowers and when they reproduce the population will eventually evolve to have more blue flowers. Effect of genetic variation is more pronounced in a small population since its easy to disturb the allele frequency.
<span>Each parent cell has the full 46 chromosomes, but during the process of meiosis, the cells are split to produce daughter cells with just the base 23. If the cells did not split and reduce the number of chromosomes, the new individual would either not survive due to having 92 chromosomes or be severely disabled. The gametes produced by a female are larger than those produced by males. This is referred to as heterogamy.</span>
Discontinuous variation <span> refer to large, conspicuous differences from the parents</span>
This is where individuals fall into a number of distinct categories, and is based on features that cannot be measured across a complete range
continious variation refer to small, indistinct differences from the normal condition.
Milk yield in cows, for example, is determined not only by their genetic make-up but is also significantly affected by environmental factors such as pasture quality and diet, weather, and the comfort of their surroundings
