<span>In a cell that is not dividing, the unwound, filamented mass of dna and associated proteins is called chromosome or chromatin. </span>
During mitosis, the cells divide and multiply into two. So multiply 18 by 2 and the daughter will have 36 chromosomes.
Answer:
A mutation is a change in a genetic sequence. Mutations include changes as small as the substitution of a single DNA building block, or nucleotide base, with another nucleotide base. Meanwhile, larger mutations can affect many genes on a chromosome. ... Other mutations result in abnormal protein products.
Explanation:
I believe the correct answer would be the third option. Our elements that comprise over 95% of the human body are <span>carbon, hydrogen, oxygen, nitrogen. Carbon and hydrogen is the backbone of any hydrocarbon or organic compound. The cells in our body are made up organic compounds thus our body is mostly composed of carbon and hydrogen. Oxygen is also present in high percent in our body since it is important for the processes of the cells. Also, nitrogen should be present in our body in large amount since it is present in proteins which is found in our body's cells and tissues.</span>
