Answer:
cancellation
Explanation:
A factor in the numerator is <em>cancelled by dividing it</em> by the same factor in the denominator. The quotient is 1, the multiplicative identity element.
Answer:
Explanation:
Mutation can cause a change in DNA to change in many ways.
Mutation is the sudden change in the genome of an organism that can be heritable from parent by their offspring.
Missense mutation - This occur when a base pair is substituted for by another leading to the formation of an entirely new amino acid.
Nonsense mutation - This occurs when a base pair is substituted for by another leading to the formation of a new amino acid. The new amino acid form therefore send a stop signal to the sequence of amino acid been built.
Insertion or deletion - Insertion mutation inserts new base pair into the sequence changing the number of the DNA base while deletion deletes a base pair changing the number of DNA base from the amino acid sequence.
Disruptive selection is made of natural selection which favor both extreme phenotype and both from one extreme in directional selection. Stabilizing selection is favors the middle phenotype, average trait value over two extreme trait values.
Both the selection are disruptive selection favors phenotype while stabilizing selection favors average phenotype in population , eliminating both extreme.Disruptive selection also known as diversifying selection.
Stabilizing selection is natural selection pursue population towards the average or median . Normally environment favors average phenotype within a population.Both are two natural selection , affect the distribution of phenotype within a population,Applies to a phenotype trait.

It is c your answer for your questions
Some of the important questions to be asked should be: Is the procedure of obtaining the results accurate? If not, by how much is its reliability? Are the results useful for further scientific research? What can you recommend to others who might want to make the same scientific conclusions?
