Answer:
The genes that the child inherited from the parents is the SS gene
Explanation:
The genetic composition of the haemoglobin genotype is given by two gene variants; A which is dominant and S which is recessive. As such, an individual can be AA, AS or SS. Individuals that are AA and AS do not show traits of the disease, but SS individuals have sickle cell anaemia.
From this example, since both parents have no symptoms and their child have sickle cell, their genotypes most likely were AS and AS. Let me show you how:
A S
A AA AS
S AS SS
From the cross above, there is a 1 in 4 chance that if both parents were AS, their child will be SS. Any other composition from the parents will not produce an SS offspring. Hence the genes that the child inherited from the parents is the SS gene.

Pollutants are substances that do harm to an environment and the beings

Hence, the answer to this item is letter A. True.
Answer:
Salt triggers osmosis by attracting the water and causing it to move toward it, across the membrane. Salt is a solute. When you add water to a solute, it diffuses, spreading out the concentration of salt, creating a solution. If the concentration of salt inside a cell is the same as the concentration of salt outside the cell, the water level will stay the same, creating an isotonic solution. Cells will not gain or lose water if placed in an isotonic solution. The raisin would swell. (please mark brainliest)
