<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.

Chromosomes are composed of deoxyribonucleic acid (DNA) mole

There are mainly two molecules that function as genetic material in living organisms.

These are ribonucleic acid(RNA) and deoxyribonucleic acid(DNA).

The organisms having DNA as genetic material require packaging of DNA as it is a long polymer of deoxyribonucleotides.

In the case of human beings, the length of DNA in a cell is approximately 2.2 meters which is very large as compared to the size of the nucleus( approximately 10^-6 meters).

So, the DNA has to be made compact for it to be present inside the nucleus of a cell.

Therefore, the DNA present inside the nucleus of a cell undergoes coiling and compaction through several stages before finally becoming a chromosome, which is shown in the adjoining diagram.

Thus, chromosomes are composed of deoxyribonucleic acid (DNA) molecules.

object forms when a supergiant runs out of fuel?a red giant a black hole a white dwarf a neutron star

LenKa [72]

<u>ANSWER:</u>

When a supergiant runs out of fuel, the object formed is either a black hole or a neutron star.

<u>EXPLANATION:</u>

Supergiant are very large stars in the galaxy that end their lives very quickly.

When a supergiant star loses its fuel, it blows itself by a supernove explosion.

When supernove explosion happens, the supernova outshines other stars in the galaxy and then slowly faded away leaving a dense object called black hole or neutron star.

This black hole or neutron star is surrounded by a mass of very hot gas and the elements of the supergiant star get scattered into the space.

Answer: The correct answer is option C

FACILITATED DIFFUSION.

Explanation: FACILITATED DIFFUSION is a form of passive transport,it is the process by which substances(molecules) move from a region of higher concentration to a region if lower concentration along their concentration gradient through the help of a membrane transporter forming a pore or channel(Protein).

Facilitated diffusion dies not require high energy to occur since a concentration gradient is involved.
