D.) = 1.)
A.) = 3.)
C.) = 2.)
B.) = 4.)
Explanation:
Protons and neutrons are subatomic particles found in the atom of any substance.
These particles collectively determines the mass number of the atom.
- Protons are positively charged particles found in the nucleus of an atom.
- Neutrons do not carry any charges and are also found in the nucleus.
- Electrons are negatively charged particles.
Electrons occupy the extranuclear space of an atom.
The correct answer is Glycogen is the body’s main source of energy, but lipids contain most of the body’s stored energy.
The glycogen is a polymer of the glucose. The carbohydrates are the main source of the energy in our body. The glucose that is left after the normal energy utilisation by the body is converted into the glycogen and stored at various location, but the most of the energy reserves of our body lies in the fats, which is stored in form of lipids.
Depends upon the temperature of neighboring elements
<u>Explanation:</u>
- The equations of heat flow in solids does not depend on which way flows up.
- The direction of heat flow in a small element within a solid depends on the temperature of its neighboring elements.
- It is due to the fact that only neighboring element can decide that heat can pass from the system or into the system.
- Heat normally flows from hot substance to cold substance.
