Answer:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Autotrophs make their own food using energy from photosynthesis.
<u>The autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into glucose. </u>
Speciation start to take place on a genetic level between two isolated populations by Allele frequencies change in different ways.
<h3><u>
Explanation:</u></h3>
The field of study called the population genetics helps us to understand about the composition of a selected population and the frequencies of alleles and how they get changed over a specific period of time. The mechanism called the adaptation mechanism ,mutation and gene flow determines the allele frequency changes in natural population.
Micro evolution refers to the changes in gene pool from one generation to another. Natural selection, mutation, genetic drift and gene flow are considered as the four forces of this evolution. When the allele frequencies starts to get changed in different ways, the Speciation starts to take place.
Is said to be denatured.
Denaturation occurs when the environment around has a extremely high temperature of extreme pH values comparing to the optimum values of the enzyme. Each enzyme has their own optimum temperature and pH.
In the case, the lost its three-dimensional structure and can no longer function because the shape of the active site is altered and thus it can no longer bind into substrates.
