Alex777 [14]

Answer:

The correct answer is option 4.

Explanation:

Viruses cannot be considered alive as they cannot carry out metabolic reactions on their own. Metabolism signifies the tendency to gather and use energy. The chemical reactions in the cells spontaneously change the molecules into the forms of energy, which can be utilized by the organism.  

However, in the case of viruses, they are too small and simple to collect and utilize their own energy. They are completely dependent upon the host cells for energy. The viruses only require energy when they need to make duplicates of themselves, however, they do not require any energy when they are present outside of the cell. Thus, as they cannot carry out metabolic reactions, they are not considered as living.

Cholesystokinin is secreted from gastrointestinal system and is responsible for stimulating the digestion of protein and fat.

Whereas oxytocin plays a major role in the childbirth, sexual reproduction and social bonding.
