Monica [59]

Answer:

lagoon

Explanation:

As the estuary gets more and more sediments, the deposition of them is constantly on the rise, affecting the landscape and forming new geographical features. With the sediments constantly building up, they eventually cut off part of the water from the sea. They will form a closed pool-like feature, filled with water, and surrounded by sediments, cut off from the sea. It will have shallow water, and because the water is stagnant and shallow it will have higher temperature than the other water. This geographical feature is known as lagoon.

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%.

To know more about colorblindness refer to the link below
