Pentose is classified as a monosaccharide (simple carbohydrate), and its molecular formula is represented by $(CH_{2} O)n$ . They are water soluble molecules with sweet taste. Monosaccharides may have from three carbon atoms (trioses) to six (hexoses). In DNA is present pentose (5 carbon atoms)

2. A nitrogenous base

Nitrogenous bases are ring-shaped compounds that contain nitrogen in their molecular structure. They are classified into two groups: purines and pyrimidines

The purine bases are adenine (A) and guanine (G). They are larger and contain more than one ring in their structure,.

The pyrimidines, cytosine (C), uracil (U) and thymine (T), are smaller and composed of a single ring.

What happens to an animal cell in a hypertonic solution?

jarptica [38.1K]

<span>The answer is that cell will shrink.</span>

<span>If you put an animal cell in a hypertonic solution means that concentration of the solutes is greater outside the cell, in the solution, than in the cell. Consequently,</span> the water concentration of the cell's cytoplasm is higher than that of the hypertonic solution. Since the aim is to balance water concentration on the inside and outside of the cell, the water will exit the cell. The cell will lose water and, consequently, will shrink in size.
