Answer:
The answer is D. One year
The nitrogenous bases placed in between the DNA double helix strands, like rungs on a ladder, are positioned there because of the hydrophobic effect and are stabilized by hydrogen bonding. The stability of DNA also relies on the interactions between the hydrogen bonds between bases, hydrogen bonds between bases and surrounding water, and base interaction between neighboring bases.
Hydrogen bonds are able to stabilize the DNA double helix by pairing up with their complementary base pairs (guanine with cytosine and adenine with thymine)
Hope this was able to help you! I went through my answer and bolded the more important parts, and parts more useful for answering the question.
Answer:
foooooooooooooooooor???????
Answer:
Because some effects will occur.
Explanation:
The positive test which was the result for the organic molecules for the water sample showed that there is some change occurs in water sample by adding of organic molecules due to which the results of the test comes positive. If there is no change occurs in the water sample by adding some organic molecules so the results will come negative which means no effect.
