The correct answer is D. Both A and C
Explanation:
In biology, a phenotype refers to a trait or characteristic that is observable in an organism, including physical characteristics, physiological characteristics, and behavioral characteristics. The phenotype is the result of the expression of genes or environmental factors. Considering this, both "a certain duck has a blue beak" and "most cheetahs live solitary lives" are phenotypes because they are traits that can be observed in terms of morphology or physical characteristics in the case of the duck or in terms of behavior in the case of the cheetah. On the other hand, a mutation is not necessarily a phenotype except if it is expressed.

Answer:
1. adaption
Explanation:
Salmon have special adaptation behavior that allows them to live in both freshwater and saline water during their lives.
<u>Salmons are born in freshwater where they spend few months and then move to saline water. For laying eggs, they again move to freshwater because eggs are unable to survive in saline water due to a process known as osmoregulation.</u>
Moving from freshwater to ocean water, salmon adapt according to the environment for their survival.
Hence, the correct answer is "1. adaption"
The interactions can be harmful because they can poison the organisms and they can be helpful because they can help improve the organisms surroundings ex. food/ water supply.
The magnitude of change in body composition after exercise training is most closely related to total energy expenditure. Energy expenditure is the amount of energy that a person needs to carry out a physical function such as breathing, circulating blood, digesting food, or physical movement. The total daily energy expenditure is therefore the total number of calories burned each day by the body.
