Question : T<span>he humpback whale can be seen off the coast of Alaska during the summer months, but is found as far south as California and Hawaii during the winter. Why would the humpback whale most likely spend the summer months off the coast of Alaska?

Answer : The humpback whale likes being in the cold like all other fishes.
The humpback whale is usually found around the coast of Alaska because it is a little colder over there. Then in winter it is found around Hawaii and California because the pacific ocean cools down and is not so hot anymore!

Which of the following is the simplest unit of a nucleic acid
Lyrx [107]
<span>Nucleotides are made of a pentode sugar, a phosphate and a nitrogen base. Nucleotides are the building blocks of nucleic acids DNA and RNA which serve as the cell's store house of genetic information. All nucleotides are composed of three parts: a five-carbon sugar, a phosphate and a nitrogen-rich structure called a nitrogenous base. The sugar can be ribose which is found in RNA, or deoxyribose which is found in DNA. The only difference between these two sugars is that deoxyribose has one fewer oxygen atom than ribose.</span>
