Cellulose is a carbohydrate which is present in the plant cells. The cellulose is a polymer with glucose as the monomer units. The monomer units of cellulose is attached by the beta linkages. The cellulose provides structural support to the plant cells by forming micro-tubules. The humans cannot eat the diet rich in cellulose because they lack the enzymes that are needed to digest them. Some animals, such as cows and termites have these enzymes but not the humans.
Hence, the answer is 'people cannot digest cellulose'.

Polyallelism.
Poly means many. So, when there are more than two alleles for the same gene locus we call it of polyallelism. This makes genetic variability much bigger because there are several alleles for a possible location in a chromosome and this would make, for example, from two parents a possible combination of two out of four possible alleles if between them they had all different alleles.

C. It is only in the heart.</h2><h2 /><h2>
</h2><h2 />
Because cardiac muscle is striated muscle "that is only present only in the heart." Cardiac muscle fibers have a single nucleus, are branched, and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and desmosomes to hold the fibers together when the heart contracts.
So, the answer will be "It is only in the heart."
