The first one, Added removed or changed. Mutation as in anything that would cause the slightest change.
The scientific definition of evolution refers to changes in a species or population over time.
Evolution is a long-term process. It may take millions of years and several generation for an evolution to occur. The cause of evolution can be genetic as well as environmental. The evolution is a result of mutation. Evolution generally gives rise to new species, that is different from its ancestral population.
Population is a group of similar type of organisms. These organisms live in the same habitat, require same resources and have same kind of habits. The most essential criteria that defines a population is that the organisms of a population can mate with each other and produce offspring.

Answer:
f = m - u
Explanation:
DNA methylation is an important epigenetic modification associated with the regulation of gene expression. As such, the analysis of DNA methylation marks and the dynamics of this process may shed light on the genes that are being expressed at a given time in a given cell type/tissue. In the example above described, f is defined as the fraction of the DNA molecule that is methylated after one (1) hour, whose value can be estimated by subtracting u fraction (i.e., fraction of methylated locations that become unmethylated) from m fraction (i.e., fraction of unmethylated locations that become methylated).
In consequence, the equation is
f = m - u
Answer:
For any experiment we can say that light waves are the electromagnetic waves because they make up what is known as the electromagnetic spectrum.
Explanation:
- Light is the moving energy form that is made up of tiny particles known as photons.
- The light waves comprises of both magnetic and electric aspects hence known as electromagnetic.
- The process of propagation of light wave is : the fields vibrates perpendicularly in the same direction of propagation of the wave, and at 90 degree angle with each other.
- Similar to sound waves, light wave can interfere with each other.
The given statement that pharmacological induction of heme oxygenase-1 by a triterpenoid protects neurons against ischemic injury holds True.
<h3>What is Heme- Oxygenase-1?</h3>
Heme- Oxygenase-1 is an enzyme that usually gets triggered when there is oxidative stress to the body.
This enzyme helps protect the body from repeated unwanted injuries.
Oxidative stress means the formation of the free radicals in the body that produce harmful effects to the human body.
Thus neutralizing these radicals is very important.
