Human bone, muscle, and nerve cells all contain the same number of chromosomes with the same complement of genes. what enables these cells to perform specialized activities?

a. the ability of some cells to remove unnecessary dna sequences
b. the regulation of gene expression within each cell type
c. the mutation of genes within each cell type
d. the use of different methods of cell division

The correct answer is B) The regulation of gene expression within each cell type.

The body of an organism is made of cells, which possess same number of chromosomes ( like 46 chromosomes in all human cells) with the same complement of genes. This means that all the specials ed cell ( performing specialized function in the body) like bone, muscle, nerve cells contain the same number of chromosomes.

The difference in their activities/ functions is primarily because of differential expression of genes. In other words, different genes are transcribed and translated in different cells resulting in the formation of different proteins. This enables them to perform different functions.

Thus, the regulation of gene expression within each cell type enables them to perform differently.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
