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.

A birds beak helps you identify its habitat by looking at its size and shape. The size and shape will give you an idea of what type of food it eats. A bird will have a beak that is suited for eating food that they find in their habitats such as seeds, nectar, insects, mice or fish. For example, pelicans live close to the ocean. Their beaks are long and they have a pouch in their throat. They catch fish by gulping them out of the water into their throat pouch. If you ever been to Daytona Beach this is a familiar sight. Not something you would see sitting on a park bench in Central Park! Hmmmm <span>sighnoah</span> THANKS!
