<span>Answer: Bone marrow stem cells have been shown to generate cartilage, bone, and muscle when injected directly into the injured site
Stem cells could differentiate into the various type of cells, makes them able to regenerate part of the body that doesn't have regeneration abilities. The cell that involved the </span><span>tear of the rotator cuff would be cartilage, bone, and muscle.

Because there are several factors that determine weight loss or gain and reducing calorific intake is just one of them (for reducing weight loss). Other factors that should be considered is exercise. Doing regular exercise ensures that the metabolic rate of the body is increased so much of the calories are burned even after intake. Having a lower metabolic rate can result to increased weight gain even with low calorie intake.
<span>The types of effects that the surgery had on the rats were documented with their bar-pressing behavior. The differences and changes from the injections effected the rats in certain ways. The location of the injection and which types that was more pleasurable for the rat is something that needs further investigation.</span>
The order in which the amino-acids are placed within the polypeptide determines the tertiary structure and therefore the function of the given protein. Amino acids have different functional groups like methyl(CH3), phenyl(C6H5). Those functional groups can interact with molecules like glucose determining reactions, the proteins that catalyze reactions are called enzymes. Other functional groups of amino acids can be the sulfate groups. For example, insulin has 2 polypeptide chains(Chain A has 21 amino acids, and chain B, 30). Between the two polypeptide chains, 2 disulfide bonds form altering its shape.
