Answer:
Salmon populations in the United States is declining due to the following factors:
1. Over-fishing and human activities have put a major influence on the population of salmon.
2. Due to industrialization, urban growth, unplanned farming, deforestation, and pollution would have imparted strains on the stocks of salmon. Apart from this chemical contamination from the industrial run-off and agricultural activities are also declining populations of salmon.
3. Genetically modified fish from hatcheries usually escape and interbreed with wild fish, thus, changing the genetic features of the populations.
4. Construction of hydropower dams is also a major cause of the salmon population declining.
Answer:
All is in order.......
stimulus is a thing or event that evokes a specific functional reaction in an organ or tissue.
homeostasis is the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
Irritability is that characteristic of living organisms in being aware of, and being able to respond to, a stimulus which tends to disturb the steady state or homeostasis which all organisms prefer for maintaining life.
Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). Being warm-blooded creatures, humans can increase or decrease temperature internally to keep it at a desirable level.

Answer:
D to produce energy-carrier molecules
Explanation:
The main function of the Krebs cycle is to produce electron carriers that can be used in the last step of cellular respiration.
For most athletes, the period in their
yearly training cycle during which it is recommended to begin calorie restriction
so as to lose significant amounts of stored body fat is the off-season or early
in the preseason. Restriction of energy intake late in the preseason when
there is rigorous training or during season when there is competition may impede training, recovery,
or performance.
Given what we know, we can confirm that the two organisms most closely related would be the human and the gorilla.
<h3>Why are the Gorilla and Human the most closely related?</h3>
Using only the information given from the diagram, we can say that gorillas and humans are the most closely related. Although the turtle and the chicken also share the same genetic similarities in the diagram, the human and the gorilla also share physical aspects between them, making them more related than the previous group.
Therefore, given that they share genetic and physical aspects, we can confirm that the two organisms most closely related would be the human and the gorilla.
