Quick growth to high densities of bacteria such as E. coli can give rise to mutants which are genetic variants within a species.
<h3>Mutants</h3>
Mutants are mutated forms of species.
Mutation refers to changes to the DNA base sequence of organisms. This can be caused by a variety of factors.
In a population of high density consisting of a single species, the frequency of mutation is usually high.
Mutation will create phenotypically different organisms within the same species population. These organisms are known as mutants and not only phenotypically different but also genetically variant.

Answer:
bone cells of human body are diploid
Answer:
The correct answer will be option-A
Explanation:
A scientific experiment is designed in a way that it tests the predicted hypothesis and so contains the three different types of variables namely: independent (can be modified), dependent (to be studied) and the control (kept constant and unchanged).
In the given question, since the scientists studied the effect of nitrate and phosphate in which he provided the plant samples with nitrate and phosphate but he missed the control sample which should lack the variable to be tested that is nitrate and phosphate. This control variable helps the scientist to study the relationship between other samples.
Thus, option-A is the correct answer.

Protons and neutrons are located in the nucleus
Electrons are located in the electron orbital
