Answer:

The correct answer is- secondary treatment

Explanation:

Wastewater treatment is divided into three main stages which are primary, secondary and tertiary stages. In the primary treatment, the wastewater is held in the settling tank for some time and the solid waste settles with time and the remaining liquid is passed for secondary treatment.

In the secondary treatment, the organic compound present in the liquid is degraded with the help of aerobic bacteria. Aeration tank is there for providing the oxygen to bacteria and wastewater is stirred so that oxygen can be distributed evenly and bacteria can do their work properly.

melisa1 [442]

Color blindness is a recessive x-linked trait in humans. In a family where the mother is color-blind, and the father is normal, the probability of their having a color-blind son is 100%.

Color blindness is a recessive x chromosome liked recessive disease which is more prone in males than in females. As the mother is color-blind she has both the alleles of colorblindness while the father is normal with both x chromosome and y chromosome normal.

So if the parents have a boy, he will always receive an x chromosome with colorblindness gene from the mother and a normal y chromosome from the father always. Thus, the probability of having a colorblind boy will be 100%.
