It will take 15 years for Della to be in the same risk of non-smoking persons in risk of cardiovascular disease. As you quit smoking, the lungs will start to purify itself, but it will take some time. On the other hand, it cannot be assured that the lungs may be totally restored, more or less it would just be clean over a period of time.

During DNA replication each stands of dna is used as a temple to produce a complementary stand of DNA this process is shown belo
castortr0y [4]
<h2><u>Full question:</u></h2>

During DNA replication, each strand of DNA is used as a template to produce

a complementary strand of DNA. This process is shown below. Which base

will attach to location 2?

A. Adenine B. Allimene C. Thymine D. Tyrosine

<h2><u>Answer:</u></h2>

Base thymine will get attached the location 2.

Option C

<h3><u>Explanation:</u></h3>

DNA replication is the process by which the genetic material that is deoxyribonucleic acid is getting replicated into its daughter DNA by the process which involves a lot of enzymes and energy. This process involves the formation of complementary base pairing between the nitrogen bases present in the nucleotides of DNA.

As the DNA replication starts the enzymes helicase and gyrase comes in action which open up the double stranded DNA which then is acted by DNA dependent DNA polymerase which gets attached to the coding strand of the DNA and starts accumulating the nucleotides from the cytoplasm and nucleoplasm that are complementary to the nitrogen base that is present on the coding strand. This process is very fast and can go up to speed of 30 to 40 base per second. This process is fully based on the complementary base pairing nature of DNA which bring the nucleotide from the nucleoplasm that is complementary to the base present on the coding strand. And this nucleotide is the same that is present on the other strand of the DNA because the DNA double helix contains the the complementary bases that actually forms hydrogen bond between themselves.

Here in the location to we can see that adenine is present as the nitrogen base. The complementary base to adenine is thymine. So the complementary base that will be present there will be thymine itself

Explain how an organism's ability to survive and reproduce can affect the entire population
inn [45]

Answer:

The organism will pass on the traits to their offspring. If the offspring also has an increased chance of survival it will have a higher chance of passing on the traits. Over a long period of time the entire population can inherit this trait.

Explanation:

According to the theory of natural selection organisms with beneficial traits are more likely to survive to the reproductive stage and pass on the beneficial gene to their offspring. <em>Natural selection selects beneficial traits.</em>
