Which best explains why muscle cells are different from blood cells?
A
Muscle cells are produced by the brain, but blood cells are produced by the heart.
B
Different genes are activated in muscle cells than in blood cells.
C
Muscles cells experience different environmental influences than blood cells.
D
A mutation occurs during the development of muscle cells but not in blood cells.
Explanation: 

Detailed explanation-1: -Which best explains why muscle cells are different from blood cells? A mutation occurs during the development of muscle cells but not in blood cells.

Detailed explanation-2: -Muscle cells and nerve cells in one species of animal owe their differences in structure to differential gene expression. This is because these two cell types have exactly the same genes and the same types of ribosomes but they each express a different subset of these genes.

Detailed explanation-3: -Muscle cells and neurons are very different, both in form and function. And the critical genes that get switched on in order to shape each type of cell’s form and function are different too.

Detailed explanation-4: -How do the DNA and genes in a muscle cell compare to the DNA and genes in a nerve cell? The DNA is the same, but different genes are activated. Through what process do cells become specialized so they can perform specific functions within organisms?
