A. Insects must occasionally shed their exoskeleton to grow a new one
<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>
Answer:
More variation assists with survival.
Explanation:
Snails are natural decomposers
The answer is B. Invasive species are successful in novel environments due to lack of a natural predator or competition. Therefore if the non-native share a niche with other fish in the lake ecosysem, there will definitely be competition for resources. This could lead to competitive exclusion of one species or resource partitioning between the species. Consequently, the non-native fish species will not invade the new environment unchecked.
