When joints are not regularly moved through their entire range of motion, muscles and ligaments eventually _____. a. shorten b.
zhuklara [117]

Answer:

a. shorten

Explanation:

Inability or failure for joints to move through their entire range of motion is caused by constrictions. These constrictions often results when the excess adipose tissues that surrounds the muscles and ligaments are not in required adequate proportion. These constrictions can be caused by ageing, fatigue, muscular diseases etc. As a result of these constriction in the joints, let say for example, the knee joint, the muscle and ligaments tends to shorten in length.

Salivary amylase is released in the mouth where it breaks down sugars. however, it is inactive once it reaches the stomach where
GREYUIT [131]
<span>Amylase needs an optimum pH for its activity. It is in the range of 6-7. Below or above pH will denature this enzyme. The pH level is optimum for this enzyme in the mouth and hence it catalyses the break down of sugar. The pH level of stomach is lower than its optimum level duet to the activity of gastric acid. Hence the enzyme becomes inactive in the stomach.</span>
