Answer:

(d) Cell wall

Explanation:

The cell wall is a structure located on the outside of the cell membrane in the cells of plants, bacteria, fungi, and algae. It is a resistant, tough and flexible layer, which has the vital function of supporting the osmotic pressure inside the cell, preventing the cell from lysis when water enters. Besides, it has the function of giving rigidity, support and defining the shape of the cell.

Red blood cells in A-positive individuals:
katrin2010 [14]

Answer:

Red blood cells in blood type A-positive individuals have the A antigen, and generate antibodies against the B antigen (option B).

Explanation:

The basis of compatibility by blood group, according to the ABO system, is due to the presence of surface antigens A and B in the red blood cells. When a specific antigen is present, the body recognizes it as its own, while the other antigen will be recognized as foreign, and will induce antibody synthesis.

Blood types are determined by the presence, or absence, of these surface antigens A and B, generating antibodies against the antigens it does not possess, which can be summarized:

  • <u>Blood type A</u><u> </u>has surface antigen A, but antibodies against B.
  • <u>Blood type B</u> has surface antigen B, and antibodies against A
  • <u>Blood type AB</u> has both A and B antigens, so it does not generate antibodies .
  • <u>Blood type O</u> has no antigens, but can produce antibodies to both antigens.

you may have read about alkaline diets that claim that you need to only eat alkaline foods in order to remain healthy according
hram777 [196]

Answer:

Mechanisms are activated where it is sought to lower the amount of free protons in the blood, that is, to reduce acidity, these mechanisms work between two large systems, the receptor system, the respiratory system and the renal system.

Explanation:

When a metabolic acidosis is entered, either by a food, or by a disease or even an intense physical activity, the lungs seek to generate hyperventilation, to increase the concentrations of oxygen in plasma and absolutely decrease the carbon dioxide concentration, thus not the blood becomes even more acidic.

On the other hand, the digestive system together with the sensory system, will warn this proprioception of the acidity of the plasma and will promote the dilution of these acids with a solvent, which is water, promoting the sensation of thirst.

Finally, the kidneys will seek to retain all the alkaline solutes to neutralize the physiological internal pH, and will release through the urine and the channels of acidic compounds, the products or acid metabolites to the external environment, that is, acid urine excretion.
