The body contains about a trillion cells
As elevation increases, air density decreases resulting in a decreased ability to hold heat.
<h3>Effect of elevation on climate</h3>
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further and the temperature decreases.
P = ρgh
where;
- P is the air pressure
- ρ is air density
- h is elevation
- g is acceleration due to gravity
As the pressure decreases, air molecules spread out further and the temperature decreases. The decrease in temperature affects the amount of heat that air can hold.
Thus, as elevation increases, air density decreases resulting in a decreased ability to hold heat.

Answer: Option B) phosphate; hydroxyl; 3'
We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the phosphate group attached to the 5' carbon atom of the sugar portion of a nucleotide and the hydroxyl group attached to the 3'
carbon atom
Explanation:
For both RNA and DNA, chemical groups such as phosphate (PO3-) attaches to the 5' carbon of the pentose sugar (deoxyribose in DNA, ribose in RNA).
While hydroxyl group (OH) attaches to the 3' carbon atom of the pentose sugar.
Thus, a nucleic acid structure structure reveals a several repeating units of nucleotides where nitrogenous base links to a pentose sugar, who in turns is linked to phosphate group
