Answer:
3. the absence of a cell wall in human cells
Explanation:
Animal cells do not have cell walls. Cell membranes separate the cytoplasm of the animal cells from the surroundings and maintain their interior. Plant cells have cellulosic cell walls. A cell wall surrounds the cell membrane of a plant cell. Cell walls serve to provide structural support and protect plant cells from pathogens. Cell walls also help keep excess water out of cells so they do not burst. Therefore, human cheek cells would not have cell walls while the onion cells would have cell walls made up of cellulose.
When insulin is deficient , GLUT4 transporters are not inserted into the cell membranes , glucose is not transported into the cells and the blood glucose concentration increases.
Insulin deficiency provides more amino acid and glycerol substrates for glucose synthesis ie increased gluconeogenesis .
With a deficiency of insulin, there is both increased hepatic glucose production through increased glycogenolysis and gluconeogenesis as well as decreased glucose use. The result is hyperglycemia.

The volume of the gas expansion is 0.71 liters.
<h3>
Boyle's law</h3>
Boyle's law states that the volume of a given mass of a gas is inversely proportional to its pressure provided that temperature remains constant.
P₁V₁ = P₂V₂
where;
- P₁ = 30 psi
- V₁ = 0.35 liters
- P₂ = 1 atm = 14.7 psi
The volume of the gas expansion is calculated as follows;
