Answer:
They are building blocks for larger polysaccharide which are important in structural rigidity of cells.
Polysaccharides such as Starch and Cellulose which are instrumental in cell structure and rigidity are formed from chains of monosaccharides.
They are also useful in the provision of energy which is used in cell functions (metabolism).
Monosaccharides such as Glucose, Sucrose are useful in provision of energy for physical and metabolic activities of the body.

Answer:
D
Explanation:
Brain can create new connection between neurons.
B. A cytoskeleton is not an organell in a eukaryotic cell. We're as Golgi, ER, and Lysosomes are all very important organells in eukaryotic cells.
<u>Answer</u>: Thermal energy----> a polar bear breaks down stored fat to increase its temperature.
Mechanical energy-------> bat emits and receives sounds to locate prey.
Electrical energy------>eel releases a current to defend itself.
Radiant energy --------> a firefly produces a green glow from its abdomen to attract mates.
<u>Explanation</u>:
- <em>Thermal energy</em> is the energy created in the movement of particles that leads to the production of heat and thus, the temperature increases. Since the polar bears break down fat to increase temperature, the energy generated is thermal energy.
- The<em> mechanical energy</em> is defined as the sum of energy of motion and the position of an object . Thus the energy produced by the bat to locate its prey is mechanical energy.
- The energy associated with the production of electromagnetic radiation is<em> radiant energy,</em> thus the glow produced by fireflies is a form of radiant energy.
- The energy produced due to the movement of electrons is electrical energy. Thus, the energy produced by an eel in the form of electric current is <em>electrical energy.</em>
