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.
Different: in covalent bonds, atoms share electrons, whereas in ionic bonds atoms transfer electrons.
Alike: Both ionic and covalent bonding lead to the creation of stable molecules.

Answer:
One of the deadliest animals on earth is the rough skinned newt. It produces highly toxic skin toxins. In the 1970s, three hunters were found dead while camping in Western Oregon when they accidentally boiled a rough skinned newt in their coffee pot. Scientists discovered that they were becoming more toxic due to a common predator: the garter snake. As garter snakes were growing more immune to their toxins, rough skinned newts were growing more toxic in what is known as an “evolutionary arms race”.
Though the genes for the garter snake immunity are most likely polygenic, however, let us assume that the immunity is caused
