The term aerobic exercise describes any type of exercise typically performed at moderate levels of intensity for extended periods of time that increases the heart rate. In such exercise, oxygen is used to "burn" fats and glucose in order to produce energy in the form of ATP, the basic energy carrier for all cells. Initially, glycogen is broken down to produce glucose, but in its absence, fat metabolism is initiated instead. Aerobic exercise is an exercise performed at a moderately high level of intensity over a long period of time. For example, running a long distance at a moderate pace.
Answer: muscle contraction of sustained force resulting from repeated action potentials. (Option A)
Explanation: Tetanus is also called physiologic tetanus. Tetanus refers to the contraction of the muscle, which is established when the motor nerve that supply nerves to a skeletal muscle produces action potentials at a very high degree.
However, tetanic contraction is usually a normal process (such as when carrying a heavy box). Also, muscles can be shorten, lengthen or remain constant length during tetanic contractions.
I think it’s
A) Calcium Sulfide
Answer: The Pulmonary Arteries
Explanation: They are two pulmonary arteries with on serving each human lungs, which brings deoxygenated blood to the lungs from the hilium. The arteries go into the capillaries of the alveoli. Capillaries are the thinnest ,smallest blood vessel,they supply oxygen to single tissues in all parts of the human body.
