Its quite difficult to understand the question
Answer:
Acquired mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.

<u>Answ</u>er:
False
,Cellular respiration not is the oxygen dependent process through which food molecules are broken down and the energy released used to generate atp.
<u>Explanation</u>:
Glycolysis is the primary phase in the collapse of glucose to abstract energy for cellular metabolism. Almost every living organisms bring out glycolysis as step of their metabolism. The method does not use oxygen and is hence anaerobic. Glycolysis occurs in the cytoplasm of equally prokaryotic and eukaryotic cells. Glucose arrives into the heterotrophic cells in two ways.
1. Over secondary active movement in which the movement occurs against the glucose concentration gradient.
2. Over a cluster of vital proteins called GLUT proteins, also called as glucose movement proteins. These transporters helps in the simplified diffusion of glucose.
Lthough much of the explanation for why certain substances mix and form
solutions and why others do not is beyond the scope of this class, we
can get a glimpse at why solutions form by taking a look at the
process by which ethanol, C2H5OH, dissolves in
water. Ethanol is actually miscible in water, which means that the two
liquids can be mixed in any proportion without any limit to their
solubility. Much of what we now know about the tendency of particles
to become more dispersed can be used to understand this kind of change
as well.
Picture a layer of ethanol being carefully added to the top of some water (Figure below).
Because the particles of a liquid are moving constantly, some of the
ethanol particles at the boundary between the two liquids will
immediately move into the water, and some of the water molecules will
move into the ethanol. In this process, water-water and
ethanol-ethanol attractions are broken and ethanol-water attractions
are formed. Because both the ethanol and the water are molecular
substances with O−H bonds, the attractions broken between water
molecules and the attractions broken between ethanol molecules are
hydrogen bonds. The attractions that form between the ethanol and
water molecules are also hydrogen bonds (Figure below). There you go
