Question

multiple choice question
diploid cells contain

one complete set of chromosomes.

two complete sets of chromosomes.

a double nuclear membrane.

two chromatids for each chromosome.

Explanation:

To solve this, we recall the definition of diploid cells. Diploid cells (denoted as \(2n\)) have two complete sets of chromosomes, one from each parent. Haploid cells have one set. A double nuclear membrane is related to cell division stages, not diploidy. Two chromatids per chromosome is a feature of replicated chromosomes (e.g., in interphase or mitosis/meiosis stages), not the definition of a diploid cell.

Answer:

B. two complete sets of chromosomes.
