Answer:

<em>The correct option is A) cadmium dosage</em>

Explanation:

In an experiment, an independent variable can be described as a factor which is changed naturally or by us to see its effect on the dependent variable. The dependent variable is the variable which is under study and depends on the independent variable.

In the following experiment, we are checking the effect of different dosages of cadmium on the surviving ability of tadpoles. Hence, cadmium dosage is the independent variable. Tadpole population is the dependent variable.

You are researching a cytoplasmic protein associated with a nerve disorder. The native form of the enzyme appears to be globular
kherson [118]

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.

describe the basic process of evolution by natural selection. Describe the underlying genetic basis and role of the environment
shepuryov [24]

Answer AND Explanation:

Darwin describes natural selection as a process whereby nature selects those organisms that have favourable characteristics to be parents of the next generation. The individuals possessing the favourable traits are better suited to the prevailing environmental conditions. This enables them to stand a better chance to survive in the struggle for existence due to limited resources.
