Yes, they can benefit an organism. That is why evolution works
Circadian rhythm, regulated by the brain’s natural clock
The answer is B. This the systolic pressure of a giraffe in comparison
to that of a human that is 100 mm Hg. This
high blood pressure ensures that the giraffe maintains 100 mmHg in the brain.
Since a high BP impairs gas exchange and increases transpulmonary filtration,
the pulmonary circulation must be separated. Therefore, in the giraffe, there
is a relatively great difference between the right ventricular and left ventricular
maximal rates of pressure ascent, the left ventricular rate of ascent being 5
times that calculated for the right ventricle.
Answer:
10% of an animals energy gets gained as you move up the food chain. the rest of that (the 90%) is used for metabolic processes or given off to the environment as heat.
