Answer:

B. They determine the structural and functional characteristics of each individual

Explanation:

Genes are present in all plants and in all prokaryotes, so answer choices A and E are incorrect. Genes are present in all living things.

Genes do determine the structural characteristics of each individual, but they also determine the functional characteristics.

Structure, which is controlled by genes, directly affects function. For example, a gene could code for a specific protein's structure, which will in turn give it a specific function.

So, the correct answer is B.

stich3 [128]

Answer:

Phase III.

Explanation:

Clinical research includes the different steps to test the particular drugs and its use for the medical treatment. Clinical research is divided into four main phases.

The phase III of the clinical research includes the double blinded study and its clinical trial on the patients. This phase determines the drug safety and efficacy. The therapeutic effect of the drug is tested directly in phase III of the clinical trial.

Thus, the answer is phase III.

The head of a phospholipid interacts with water because it is
Delvig [45]
Hydrophilic

A phospholipid is comprised of a phosphate hydrophilic head, which means that it is "water-loving," and a fatty acid hydrophobic tail, which is "water-hating." The head and the tail are joined together by a glycerol molecule. 

The phosphate head is attracted to water because it is charged (i.e. negatively). Water is a polar molecule, which means that there is an uneven distribution of charges within its molecular structure with the oxygen side being "more negative" than the rest of the atom (which is "more positive" near the hydrogen). Thus, the negatively-charged nature of the phosphate head and the parts of the water molecule which are positively charged enable the two to form an "attraction" towards one another. 

On the other hand, the hydrophobic tail is nonpolar, which means that it does not have a "more positive" or "more negative" side or part in its molecular structure. These differences in structure with water make the hydrophobic tail unattracted to water molecules and more attracted to other uncharged, nonpolar molecules (such as fats and oils).
