Answer: d) The volume occupied by the molecules themselves is no longer negligible. This most be the answer because a, b and c don't make any sense at all.
Explanation:
The answer is spontaneous mutation .
Sometimes genes, for no known reason(s), change their form in a process called spontaneous mutation.
Mutation is the actually the alteration of the nucleotide sequence of the genome of an organism, virus, or other genetic elements permanently.
Spontaneous mutation : It is a process in which gene automatically for no reason change their form.

Answer:</h3>
Partial pressure of He(P(He) = 1.5 atm.
Partial pressure of Ne(P(Ne) = 1 atm.
Partial pressure of Ar(P(Ar) = 0.5 atm.
<h3>
Explanation:</h3>
According to Dalton law of partial pressure the sum of partial pressures of individual gases in a gaseous mixture is equivalent to the total pressure.
The partial pressure of a gas in a gaseous mixture is given by the product of the mole fraction and the total pressure.
Our gaseous mixture contains He, Ne, and Ar and the total pressure is 3 atm.
Since we are given the ratios of the gases in the mixture, we can calculate the partial pressure of each gas.
P(He) = 3/6 × 3 atm.
= 1.5 atm.
P(Ne) = 2/6 × 3 atm.
= 1 atm
P(Ar) = 1/6 × 3 atm.
= 0.5 atm
Therefore, the partial pressures of gases He, Ne and Ar are 1.5 atm, 1 atm, and 0.5 atm respectively.
