Answer: The answer is disease.
Answer:
The correct answer is B:
HR = 80% of age-predicted maximum is NOT a reason to stop maximal GXT.
Explanation:
<u>Maximal graded exercise test</u> allows physicians to evaluate patients ability to perform cardiovascular exercise (functional capacity), an also detect if there are any zones of ischemia in the muscle heart due to arteriosclerosis.
To do so, the patient would be asked to walk on a treadmill and speed and slope of the treadmill will be increased gradually during the test. EKG, heart rate, and blood pressure will be recorded and compared afterwards.
The heart rate target to make a proper evaluation is 85% of the maximal predicted heart rate.
Josie stands doing active progressive muscle relaxation. once a group of her muscles exists contracted sufficiently, she should hold them in this state of tension for up to 8 seconds.
<h3>What is progressive muscle relaxation?</h3>
A non-pharmacological technique for deep muscle relaxation called progressive muscle relaxation is based on the idea that tension in the muscles is the body's psychological reaction to ideas that make one anxious, and that muscle relaxation reduces anxiety. All you require are concentration, focus, and a peaceful area where you won't be interrupted. The secret to using this technique is to contract each muscle group and hold the contraction for 5 seconds. You then exhale and wait 10 to 20 seconds for your muscles to completely relax before moving on to the next muscle group.
The creation of a sense of well-being, lowering blood pressure, and decreased muscle tension, which reduces the body's requirement for oxygen and lessens weariness and anxiety, are just a few advantages of progressive relaxation.
Hence, Josie stands doing active progressive muscle relaxation. once a group of her muscles exists contracted sufficiently, she should hold them in this state of tension for up to 8 seconds.

Answer:
The correct answer is e. all of the above.
Explanation:
Nurse cells are also called sertoli cells and are located in the seminiferous tubules in the testes. They provide nourishment to the growing sperms by providing nutrients from surrounding cells.
During the development of of sperms they become genetically different from other cells so nurse cells form blood testes barrier to protect them from immune cells.
Nurse cells concentrate the testosterone in seminiferous tubules which is necessary for proper development of sperms. They also secrete inhibin which stop FSH secretion from anterior pituitary therefore regulate the spermatogenesis.
