Llana [10]

Answer:

46 chromosomes

Explanation:

Humans are diploid organisms i.e. they contain two sets of chromosomes (each set from each parent). Each set is 23 chromosomes, hence, two sets will be 23 pairs or 46 chromosomes. This means that each somatic/body cell will contain 46 individual chromosomes.

According to this question, DNA was extracted from a cheek cell. If one could magnify the extracted material, there would be 46 individual chromosomes from each of these cheek cells, considering that cheek cell is a somatic cell.

Biomass pyramids show the amount of organic material at each trophic level; thus, they are the best type of ecological pyramid to use in order to model the flow of matter through an ecosystem. A numbers pyramid would not as accurately display this kind of information because a larger producer, such as a tree, which contains a great deal of matter, would be able to feed hundreds or thousands of small first-level consumers such as wood-eating insects.
