The right answer is A) Salt in the bloodstream causes fluids to enter the blood from surrounding cells, due to osmosis.
The circulatory system of the body is a highly flexible vascular system, which has the ability to open and distend new capillaries and veins in order to cope with an increase in fluid volume.
The term "Higher blood pressure" implies that an excess of salt leads to the retention of additional fluid within the arterial circulatory system, which would cause an increase in blood volume and add pressure to the walls. arteries.
Answer:
Tertiary.
Explanation:
Primary structure of proteins refers to the order of amino acids that make up the protein. The heme is an nonprotein non-amino acid, so it is not involved at this stage.
Tertiary structure of proteins is the overall 3-D folding of the protein (it comes after secondary, which involves folding into a repeated pattern). The heme bonds to its correct position on the hemoglobin during this stage and helps in correct folding.
