Which of the following group of monosaccharaides are all ketose? A. Dihydroxy acetone, Fructose and Ribose

B. Glyceraldehyde, Ribose and Glucose

C. Dihydroxy acetone, Ribulose and Fructose
D. Glyceraldehyde, Ribulose and Glucose

Fructose is a ketose. Monosaccharides can exist as a linear chain or as ring-shaped molecules; in aqueous solutions they are usually found in ring forms (Figure 3).

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
