Answer:
A high-sodium diet could damage the body over time as it may cause hypertension, heart failure, kidney disease, stroke etc.
Explanation:
Human body needs a small amount of sodium to perform functions like maintaining the proper balance of water and minerals, nerve impulse transmission, and contraction and relaxation of muscles. It requires about 500 mg of sodium daily to perform these important functions.
But a high-sodium diet can lead to hypertension (high blood pressure), heart disease, kidney disease and stroke. It can also cause depletion of calcium from the bone resulting in osteoporosis. Excess sodium in the blood causes the body to hold onto more water to dilute the sodium, which increases the amount of fluid surrounding the cells and the volume of blood in the bloodstream. The increase in blood volume causes more pressure on the blood vessels and the stiffening of blood vessels, which leads to high blood pressure (hypertension) and more work for the heart. This causes more burden to the heart resulting in heart attack and stroke.
Commercially processed foods like bread, pasta, soups, chips etc contains high sodium than naturally processed food like fruits, vegetables, whole grains, nuts, dairy products etc.
The ideal intake amount of sodium for a normal, healthy individual is 2,300 mg per day. For persons having high blood pressure or cardiovascular disease, the recommended amount is 1500 mg or less per day.
Answer:
A controlled experiment is simply an experiment in which all factors are held constant except for one: the independent variable. A common type of controlled experiment compares a control group against an experimental group. All variables are identical between the two groups except for the factor being tested.

Explanation:
Gamete formation involves the random and independent segregation of alleles. During anaphase 1 (meiosis), occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair.
The number of gametes with different combinations is 2ⁿ, where
n = number of homologous pairs.
In the exposed example there are 4 pairs of chromosomes, so
the number of possible combinations of chromosomes = 2ⁿ = 2⁴ = 16
Individual: AaBbCcDdEe
You can make use of the fork line method to easily figure out the possible gametes.
