SCORPION-xisa [38]

Upwelling is important to mix the nutrients that are present deep inside the water.Updewelling is a phenomenon in which the deeper water rises and gets mixed to the surface water to promote the growth of phytoplanktons and seaweeds as the water that is present deep inside is rich in nutrients.These phytoplanktons serve as as source  of energy for large fishes and other aquatic animals. As these large animals are higher in population and are an important part of food chain and they also provide food to different marine mammals ,sea birds.The deep water infuses  with costal water so to serve as a fuel for high productivity of marine ecosystem.

The genes for sex-linked traits are carried on either the X or Y chromosome. Duchenne muscular dystrophy (DMD) is a recessive, s
morpeh [17]
There is a 50% probability that the child will be a boy. If this is the case, he will inherit the X chromosome from his mother and the Y chromosome from his father. Since the woman has DMD, the boy will certainly inherit the disease, since he only has one X chromosome and it carries the disease. We know that both of the mother's X chromosomes carry the disease because since it is recessive, both of her chromosomes must have it in order for her to have it. 

There is also a 50% probability that the child is girl. If this is the case, she will inherit a normal X chromosome from her father and the disease-carrying X chromosome from her mother. Since the disease is recessive, she will not be affected by the disease, since she has one healthy X chromosome and one disease-carrying one. 

If the child is a girl, there is a 0% chance that she will have the disease (although she will be a carrier). 

If the child is a boy, there is a 100% chance that he will inherit the disease. 

The answer is D)

disa [49]

The amount of glucose in each ml of their blood will be 0.00138 g.

<h3>Blood glucose concentration</h3>

The concentration of glucose in the person's blood is 1.38%.

This means that there is 1.38 g of sugar per Liter of blood.

1 Liter of blood contains 1.38 g of glucose, and there is 1000 mL in 1 Liter of blood.

1000 mL contains 1.38 g

1 ml contains = 1.38 x 1 / 1000 = 0.00138 g

This means 0.00138 g of glucose will be present in every 1 mL of the person's blood.
