Answer: Exercise causes the heart to pump blood into the circulation more efficiently as a result of more forceful and efficient myocardial contractions, increased perfusion of tissues and organs with blood, and increased oxygen delivery. Aerobic exercise trains the heart to become more efficient.
Explanation:

Answer:
Pretty much the more activity you do, or the more intense it is, the faster your heartrate will be. Your heart needs blood, and when you're exercising the blood is pumping through your body faster.

Each position of a codon can be occupied by one of four nucleotides. What is the minimum number of nucleotides per codon necessary to specify all 20 of the amino acids that are found in proteins
Answer:
The minimum number of nucleotides per codon necessary to specify all 20 amino acids that are found in proteins is 3
Explanation:
There are four nucleic acids in the RNA, adenine uracil, guanine, cytosine. Each of them combines in groups of three to give the different amino acids. In total, there are 64 different combinations of nucleic acids that codify the 20 amino acids that we need for our vital functions.

In an ecosystem, what happens to the atoms of certain chemical elements, such as carbon, oxygen, and nitrogen? * They move into and out of living systems. O They are only found in abiotic factors. O They move out of living systems and do not return. O They move into living systems and remain there.
Answer:
They move into and out of living systems
Explanation:
The gases in an ecosystem like carbon, nitrogen, and oxygen all move into and out of the living systems through the process of animal respiration and plant absorption of carbon and release of oxygen. They are found on diffused forms in blood and cells of body, can be found in aquatic and terrestrial components. They are processed through animal wastes and in the consumption of matter.HURRY LAST QUESTION TEST DUE IN 5 MINUTES !!!!!!
