The correct answer is predatory birds.
The flowing of toxic chemicals and heavy metals into the water body when the agricultural, industrial, and human wastes run off or are discharged intentionally into the water body is known as biomagnification. These pollutants result in genetic mutations, disease, reproductive difficulties, birth defects, death, and behavioral modifications in various marine species.
However, the extremity of the destruction varies significantly among the species. In various circumstances, the animals close to the top of the food chain are most influenced by the procedure of biomagnification.
Several of the harmful toxins get settle at the lower level in a water body and are then consumed by the species, which feed or live on the bottom dwellers. As these constituents are not digested, they gathered inside the bodies of the species, which consumes them.
It signifies that the higher level predators, like fish, birds, or marine mammals accumulate more harmful concentrations of toxic substances in comparison to the animals lower on the food chain. Thus, in the given case, the more concentrated amount of toxins would be found in the predatory birds.
Let's say that the genotype of the couples are:
Cc and Cc. Notice that one is capital and the other is not. This is what shows that they are heterozygous. We put this now in a Punnet Square:
C c
C CC Cc
c Cc cc
This means that there is a 75% chance that their children will have a cleft-chin and 25% will not.
The probability is the same with each off-spring. So the answer would be 75% chance the same probability for all subsequent children.

North East trade winds and South East trade winds
Answer: d. return leaked fluids back to the cardiovascular system.
Explanation:
The lymphatic system is a web of vessels and tissues that transfers clear fluid that is called as the lymph. The lymphatic system spreads all over the body and filters and clean up the lymph, abnormal cells and pathogens. The filters traps the foreign particles from the blood. It also promotes the filtered fluid to reach back to the cardiovascular system and distribute to all the parts of the body in the form of blood.
