Which of the following statements regarding the genetic material of cells and viruses is true? A. The genes of both viruses and cells are enclosed within a nucleus. B. Viral genes may be encoded by DNA or RNA, but cellular genes are always encoded by DNA. C. The characteristics of cells are encoded in genes, but viruses do not have their own genes. D. The nucleotides found in cells are different from the nucleotides found in viruses.

Option B. Viral genes may be encoded by DNA or RNA, but cellular genes are always encoded by DNA.

Explanation:

Virus is a unique organism having unique characteristics which act as both living and non living. In cell, it is living while outside the cell it is present in crystalline form. Virus is composed of two genome i. e. DNA or RNA. But cell is composed of only DNA genome. There is no nucleus present in virus. Mitochondria and ribosome are also absent.

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.
