A) Genetic drift is the random increase or decrease of genes in a population. Natural selection is not random.
Genetic drift is the change in the frequencies of alleles in a population due to chance events (random survival). Genetic drift exhibits strong effects in small populations and plays a smaller role the larger the population gets. Natural selection is the non-random change in the frequency of alleles in a population over time, because the change in frequency of the alleles is dictated by the different relative fitnesses that different alleles confer.
They store and conserve the water that they receive rarely
<span>A catabolic reaction is one type of the two major metabolic reactions. Catabolic reactions is the breakdown of organic molecules for energy. It involves the process of breaking apart molecules into smaller molecules to release energy. Hydrolysis is the way in which this process is done.One life process that this occurs in is the digestion process when when sugars and fats are broken apart for energy.</span>
In biology, a spore is a reproductive structure that is adapted for dispersal and surviving for extended periods of time in unfavorable conditions. Spores form part of the life cycles of many bacteria, plants, algae, fungi and some protozoa
