Answer:
Option (c).
Explanation:
Carbohydrates may be defined as the polymers of the sugars and one of the most important biomolecule of the living organisms. Carbohydrates plays an important structural and functional role.
Carbohydrates are always present on the exoplasmic surface of the plasma membrane. The are present in the association with the proteins and lipids as glycoproteins and glycolipids. These carbohydrates acts as the signaling molecule that display information on cell surface.
Thus, the correct answer is option (c).
Answer:
Option 3. Genetic material
Explanation:
The answer is <span>B. It can reproduce quickly.
A single-celled organism, as its name explains, consists of only one cell. This cell must be small because, in a large cell, it would be needed a great time for information, nutrients and other molecules to travel from one part of the cell to another (choice A. is eliminated). That small cells are able to reproduce quickly because their dimension allows them to divide to new cells quickly (even 20 minutes). Still, although it is only one cell it must maintain its structure (choice C is eliminated), and cannot tolerate all environmental conditions (choice D is eliminated).</span>
Because the genes can come from distant relatives of either parent. The environment may also affect their features
The difference is the second answer choice.
