Answer:
Explanation:
An element only has <u>one</u> type of atom and cannot be broken down by chemical means.
Let's analyze the answer choices.
1. This has two types of atoms, so it cannot be an element. It has more than one type of atom.
2. This has two types of atoms that are bonded together. It cannot be an element because there is more than one type of atom and the bonds can be broken.
3. This has one type of atoms, so it is an element.
Therefore the best answer choice is 3.

Within a phase, a change in heat causes the temperature of the substance to change as the kinetic energy of the molecules changes. During a phase change, however, a change in heat causes a change in the potential energy of the molecules and the temperature will stay the same.
<h3>What is Potential energy?</h3>
Potential energy may be defined as a form of accumulated energy that relies upon the comparative situation of diverse parts of a system.
The above passage determines the differentiation between the kinetic and potential energies with respect to temperature and phase change.
Therefore, it is well described above.

Explanation:
The very primitive and early microorganisms on the earth's surface were protobionts. Protobionts are cell-like microscopic structures, and they are made up of organic and inorganic molecules present in a lipid bilayer membrane. The layers of the lipid membranes were folded into bilayers and transformed into a bubble shape when placed in water. These membranes were selectively permeable and also observed shrinkage and swelling in osmotic conditions. Protobionts also possess the characteristics of reproduction.
