Answer:

The 3 major observations were:

1. More individuals are produced each generation that can survive.

2. Phenotypic variation exists among individuals and the variation is heritable (through parents' genes).

3. Those individuals with heritable traits better suited to the environment will survive.

Explanation:

Charles Darwin was a British naturalist who proposed the theory of known to everyone as 'The Theory of Evolution' through natural selection.

The graph that best shows the general relationship between the temperature of a gas and the speed of the molecules in that gas is B.

<h3>What is kinetic energy?</h3>

Kinetic energy is the energy that an object or particle has as a result of its motion. When work transferring energy, is done on an object by applying a net force, the object accelerates and goes under kinetic energy.

The missing graphs are attached as image.

The average kinetic energy of gas molecules is

$K=\frac{3}{2} k_{B}T$

K∝T

So as per above equation, K-T graph is a straight line having a finite slope and passing through the origin.

Thus, option B is correct.

The element fluorine's outermost energy level can hold eight electrons. Study the diagram of fluorine, and then determine if the

Bingel [31]

<h2>The answer is False</h2>

Explanation:

Fluorine is a Chemical element. Its symbol is F. Its atomic number is 9. Fluorine is a lightest in nature. It is a diatomic pale yellow gas.

Except helium, neon and argon, fluorine is highly reactive to react with other elements.

The reason for it is false, because the outermost energy level of fluorine is not filled.

Fluorine becomes stable, when it forms an ionic bond with another atom.
