The answer is duplications.
Gene family consists of several similar genes. Duplications of single genes, exons, multigene families, or whole genome have given rise to families of related genes. The example is the globin family of genes in primates. About 500 million years ago, a duplication of single globin gene began. Much later, during primate evolution, the additional duplications occurred together with some point mutations. So the end result is diversity in globin chains that arose from original globin gene.
Jenna is correct because homeostasis is when you maintain a steady temperature pattern throughout your body.
The correct answer is option A, " Energy production"
Reason:
The intracellular communication is the process through which one cell interacts with other cell for proper functioning of the body. The two major types of intracellular interaction involve:
a) Chemical Synapse – In this a chemical released by one cell is detected by receptor on another cell. For example the transmission of sodium and potassium ion across the membrane through the binding of Acetylcholine (Ach) with ACh receptors.
b) Electrical Synapse – In this the cell which are connected through non selective, low – resistance pore between pre- and postsynaptic neurons known as gap junction.
This is the case in option B, C and D.
A. True! Strategic always has “strategies”
