Answer: salt intake increases the sodium level in the blood and will make the body retain excess water thereby giving the heart more work to do.
Explanation: Eating salt increases the quantity of sodium in blood and it creates an imbalance in the sodium and potassium levels. The high level of salt reduces the ability of the kidneys to excrete water. Too much sodium increases blood pressure because it holds excess fluid in the body and that results to an added burden on the heart. Excess sodium intake will increase risk of osteoporosis, stomach cancer, stroke, heart failure and kidney disease.
The result is a higher blood pressure due to the fact that the body will have the tendency of retaining more fluids because of the excess salt.
initially as temperature increases rate of photosynthesis increases, but after reaching on climax, due to scarcity of water, it starts to decrease

<span>Antigens are molecules capable to induce an immune response, "targeted" by antibodies. Antigens are usually proteins, peptides, or polysaccharides but they can combine with lipids and nucleic acids and form more complex antigens (lipopolysaccharide). Usually, antigens are exogenous (foreign substances), but sometimes are part of the host itself (in an autoimmune disease). All of them contain an epitope which is a part of an antigen that can be recognized and bound by an antibody.</span>
Multicellular organisms arise in various different ways, for example by cell division or by aggregation of many single cells.
