Answer:
The sympathetic nervous system is involved in preparing the body for stress related activities; the parasympathetic nervous system is associated with returning the body to routine, day-to-day operations. The two systems have complementary functions, operating in tandem to maintain the body's homeostasis.
Answer;
-Inactivation; limited
Differentiation requires inactivation of particular genes to produce populations with limited capabilities that form tissues.
Explanation;
-Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression.
-Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.
-Gene expression plays a critical role in the morphological changes that take place in a developing embryo and fetus and in the differentiation of stem cells to form specialized cells.

mitochondria are famously known as the powerhouse of the cell since it is the
one that gives the cells energy that is also used by the human being. This energy conversion is called oxidative
phosphorylation. Mitochondria are found in eukaryotic cells, including
humans. These organelles also had its
own genome, or what we called as DNA which is known as mitochondrial DNA, or
mtDNA which is present in the mitochondrial matrix. The role of mtDNA or mitochondrial DNA is to
convert the energy from food into any other forms that it thinks the cell can
use. It is containing 37 genes which are
all necessary for a normal mitochondrial function.</span>
