Mutation can be defined as the change in the genetic sequence that is hereditary. The example of beneficial mutation can be the change of rabbit color to help him hide from the predators.
The mutation can be caused by the exposure of the gene sequence to the mutagen that cause the hereditary change.
The mutagens can be UV radiation, high energy, radiation, chemicals, or environmental factors.
The beneficial mutation can be given as the mutation in which the organism has been benefitted. The change in the color pf rabbit benefit him in hiding from the predators. Thus, option A has been the example of the beneficial mutation.

A
Explanation:
The scientist that performed the cathode ray experiment leading to the discovery of electrons is the scientist Sir Joseph John Thompson or J.J. Thompson. It was theorized after the discovery that electrons are present in the atom. In this model, the atom is composed mainly of electrons. It was describe as plum pudding because the electrons are dispersed within the atom.
John Thompson is the answer
What are the coefficients that should be added to balance this equation? Use complete sentences to explain your answer.
Explain how this chemical reaction demonstrates the conservation of mass.
Answer:
Start by balancing the carbon atoms:
There is one carbon atom on each side of the equation, so carbon is already balanced.
Next, balance the hydrogen atoms:
There are four hydrogen atoms on the left (in CH4), so we need four HCl molecules on the right to balance the hydrogen atoms. The equation now becomes:
CH4 + Cl2 → CCl4 + 4HCl
Now, balance the chlorine atoms:
There are two chlorine atoms on the right (in CCl4), so we need two Cl2 molecules on the left to balance the chlorine atoms. The equation now becomes:
CH4 +
Explanation:
Even though the number of atoms on the left side (reactants) is 7 and on the right side (products) is 9, the law of conservation of matter is still upheld. This is because we need to consider the coefficients (the numbers in front of each compound) to account for the total mass. When you balance the equation and adjust the coefficients, you'll find that the total number of atoms remains the same on both sides, satisfying the law of conservation of matter.
