parasympathetic nervous system
sympathetic first and then parasympathetic nervous system
parasympathetic first and then sympathetic nervous system
sympathetic nervous system
Answer:
When the parasympathetic nervous system (PSNS) is activated, it slows our heart and breathing rates, lowers blood pressure and promotes digestion. Our body enters a state of relaxation, and this relaxation breeds recovery
Stimulating the vagus nerve stimulates the parasympathetic nervous system, which in turns reduces our neurophysiological experience of stress. It reduces our heart rate and blood pressure. It influences the limbic system in our brain, where emotions are processed.

why does the central part of a red blood cell appear paler than the outer part when viewed under a light microscope
Answer: The central pale area of each red blood cell is due to the concavity of the disc.
Explanation:
The absence of a nucleus and light effect makes the central part of a red blood cell appear paler
The red blood cells ( RBC )does not have a nuclei like every other cells contained in the body. therefore when viewed under a light microscope the outside of the red blood cell will appear brighter ( pink ) while the center of the red blood cell will appear pale ( whitish ). also the the light intensity from the light microscope contributes to the pale nature of the central part of the red blood cell.

d. nucleic acids
Answer:
c. lipidsExplanation:
As,
A lipid is a phospholipid, a major structural component of all cell membranes. It is composed of a glycerol molecule, two fatty acids
The type of biomolecule that is made up of fatty acids is Lipids and thus, option C is the correct answer.
Nucleic acids, Lipids, Proteins, and Carbohydrates, are some of the significant biomolecules. The characteristics of lipids are listed as follows:
The organic molecule that is specifically related to fatty acids and can be able to dissolve only in organic solvents and not in water are called lipids. The lipid molecule is composed of 1 molecule of glycerol and 3 molecules of fatty acids that are linked to one another. Oils, waxes, fats are some examples of lipid molecules.Thus, we can conclude that lipids are the type of biomolecules which is made up of fatty acids.

Which type of bonds form between the oxygen and hydrogen atoms of within a water
molecule
Answer:
covalent bonds
Explanation:
Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other. Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge. The area around the oxygen is somewhat negative compared to the opposite, hydrogen-containing end of the molecule, which is slightly positive.
