Without genetic variation there would not be evolution. genetic variation sometimes is a result of a change in the environment. some variation occurs to help the animal better survive in their habitat. maybe there was a disruption in their ecosystem and their species will become vulnerable unless they change somehow
Answer:
This signifies that the protein primarily comprises multiple polypeptide chains connected together with the help of disulfide bonds. The enzymes may be found in the form of dimers, trimers, or tetramers. Various examples of dimers, trimers, and tetramer proteins are known, of them, NEMOs dimers are considered to be held by disulfide bonds.
Thus, it can be hypothesized that the enzyme under examination is a multimer held in combination by disulfide bonds, with each comprising catalytic sites. On breaking of disulfide bonds, the enzyme dissociates into its many single units.
This illustrates the reduction in catalytic activity. Each active site in a single unit will work, however, at a gradual rate. This also shows detection of multiple globular proteins after disulfide reduction.
Active transport is a cellular transport mechanism. It’s the movement of molecules that are assisted by enzymes along the way to a higher concentration.

1) carries food and oxygen to the different cells of the body; 2) carries body wastes away; 3) protects the body from diseases; and 4) serves as the body's defense system.
it is one of the transport systems of the human body that is composed of the heart, the blood and the blood vessels. Its functions include: 1) carries food and oxygen to the different cells of the body; 2) carries body wastes away; 3) protects the body from diseases; and 4) serves as the body's defense system.
