Complete Question:
Which statement best describes a change that usually takes place in the human body when the heart rate increases as a result of exercise?
Group of answer choices.
A. More oxygen is delivered to muscle cells.
B. Blood cells are excreted at a faster rate.
C. The rate of digestion increases.
D. No hormones are produced.
Answer:
A. More oxygen is delivered to muscle cells.
Explanation:
An aerobic exercise refers to all forms of physical activity that an individual engages in, so as to increase the heart rate (from low to high intensity) in response to the level of oxygen required by any activated or working muscle in the human body.
Generally, aerobic exercise help various individuals to prevent cardiovascular diseases because it makes the heart to beat faster (heart rate increases) to enable it supply more oxygen, which makes the heart to effectively and efficiently pump blood more.
Some examples of aerobic exercise (cardiofitness activity) includes cycling, swimming, jogging, walking, skiing etc.
Hence, the statement which best describes a change that usually takes place in the human body when the heart rate increases as a result of exercise is that more oxygen is delivered to muscle cells.

Walruses live in the Arctic and have a thick fat layer. The ancestors of the modern-day walruses might not have had such a thick layer. Over time, the walruses have probably changed. According to the theory of evolution by natural selection, what is the most likely reason that this change has probably occurred?
Answer:
The walruses that had thicker fat layers were more apt to survive and live to reproduce
Answer:
Explanation:
The walruses gained a thicker layer overtime because they adapted to the cold environment allowing them to slowly grow a thicker layer of fat.

Explanation:
True or false wave energy can travel in all directions
Answer:
TRUE
The direction of energy transfer is perpendicular to the motion of the waveA: Waves do not always travel in the same directions as the currents. Waves are created by the wind and then radiate in all directions away from the disturbance. Currents represent the movement of water particles which is controlled by winds and density differences. Waves and currents can travel in opposite directions
