Which best explains why viruses do not have special structures or enzymes that allow them to make their own food? Viruses can use energy of living cells that they infect. Viruses can replicate inside a host that they infect. Viruses can cause contagious illnesses in host cells. Viruses integrate their RNA or DNA into infected cells.

Viruses can use energy of living cells that they infect

Viruses can replicate inside a host that they infect this is the reason why viruses do not have special structure or enzymes that allows them to make their own food. They just replicate and infect but they never make their own food.

Viruses depend on the host cells that they affect to reproduce. When found outside of host cells, viruses live as a protein coat or capsid, sometimes contained within a membrane. The capsid surrounds either DNA or RNA which codes for the virus elements.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
