Natural selection acts by taking advantage of natural variations in the traits of organisms within a population what is the ultimate source of this variation

Answers

The answer is the mutations within the genetic code. 

Natural selection is one of the basic mechanisms of evolution by which species adapt to their environment in order to increase their chance of survival and reproduction. In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. But, the sources of this genotype variations are not changes in the environment, nor response to the stress, but the mutations in the genome of the organism. If a mutation is not lethal, it could remain in the population, increasing the variation is some traits.

Which of the following best describes the structure of the sides of the DNA molecule? a double helix b alternating c single helix d twisted

Answers

a double helix best describes the structure of the sides of the DNA molecule. The correct option is A.

Thus, Deoxyribonucleic acid, or DNA, has a double helix-like structure. It is made up of two lengthy nucleotide strands that are spirally coiled around one another.

The complementary nitrogenous bases adenine (A) and thymine (T) and cytosine (C) and guanine (G) form hydrogen bonds that hold the two strands together.

This double helix structure is frequently compared to a spiral staircase or a twisted ladder.

Thus, a double helix best describes the structure of the sides of the DNA molecule. The correct option is A.
