Mitosis forms two daughter cells. The daughter cells will be exactly the same as the parent cell. Skin cells, liver cells, and generally all somatic cells undergo mitosis besides sex cells.
The correct option here would be A. Evolution has to do with species changing over time while natural selection is a process that leads to evolution.
<h3>Evolution and natural selection</h3>
Evolution refers to the gradual changes to the morphological and or physiological characteristics of living organisms over time as a result of constantly trying to adjust to their environments.
Natural selection, on the other hand, refers to one of the processes through which evolution takes place. It refers to forces that select for or against traits in organisms.

Answer: b. causes the gastric glands to increase production of gastric juice.
Explanation:
The parasympathetic nerves are part of the autonomous nervous system. The parasympathetic predominates mainly during "passive responses" of the organism, such as satiety, rest and digestion. Its functions are: Promotes energy conservation, Reduces heart rate, Promotes glandular secretion, Protects the retina from excess light, Promotes emptying of cavities, Promotes rest and repair, Physiologically antagonizes sympathetic nervous system.
Uptake of O2 by the blood in the lungs is controlled primarily by----.the PO2 of alveolar air.
option D is correct.
How o2 is transported in the blood mainly by?
Hemoglobin is the primary carrier of oxygen in humans. Approximately 98% of total oxygen transported in the blood is bound to hemoglobin, while only 2% is dissolved directly in plasma
Where does oxygen bind to hemoglobin?
. Oxyhemoglobin is formed during physiological respiration when oxygen binds to the heme component of the protein hemoglobin in red blood cells. This process occurs in the pulmonary capillaries adjacent to the alveoli of the lungs.
How is oxygen transported in the blood ?
-Most O2 is transported by hemoglobin as oxyhemoglobin (Hb—O2) within red blood cells. -the heme portion of hemoglobin contains four atoms of iron, each capable of binding to a molecule of O2. -oxygen and hemoglobin bind in an easily reversible reaction from form hemoglobin
