Identify and describe the three ways that mutations affect organisms?

Soloha48 [4]

Answer:

The ways that mutation can affect an organism include:

Changing the physical characteristics of the organism.

It can impact the way that the DNA is able to code the genetic information.

Also, mutation can lead to the death of an organism.

What is mutation?

Mutation simply means a change in the DNA sequence of an organism. It can result from DNA copying mistakes that were made during the cell division.

Mutation can affect an organism as it changes the phenotype of the organism. It can also impact the way that the DNA is able to code the genetic information and lead to the death of an organism.

Based on the molecular structures of chloromethane and methane shown, a student makes the claim that a pure sample of chlorometh

goblinko [34]

Answer:

Yes, chloromethane has stronger intermolecular forces than a pure sample of methane has.

Explanation:

In both methane and chloromethane, there are weak dispersion forces. However, in methane, the dispersion forces are the only intermolecular forces present. Also, the lower molar mass of methane means that it has a lower degree of dispersion forces.

For chloromethane, there is in addition to dispersion forces, dipole-dipole interaction arising from the polar C-Cl bond in the molecule. Also the molar mass of chloromethane is greater than that of methane implying a greater magnitude of dispersion forces in operation.

Therefore, chloromethane has stronger intermolecular forces than a pure sample of methane has.
