The DNA in eukaryotic cells is enclosed in the nucleus, while the DNA in prokaryotic cells is not separated from the rest of the cell's contents.
Some animals have adaptions to their circulatory system that enable them to transfer heat from arteries to veins, warming blood returning to the heart. This is called a countercurrent heat exchange; it prevents cold venous blood from cooling the heart and other internal organs.
I hypothesize that the plants that are the closest to the window are growing at a faster rate due to the amount of sunlight it may have been receiving. Therefore, I predict that the more sunlight a plant receives the faster it may grow.
(I do not actually think this. I just hope this helps you)
<span>DNA, also known as deoxyribonucleic acid, belongs to a class of polymeric organic macromolecules called nucleic acids.
The only other member of this class is ribonucleic acid, or RNA.
Nucleic acids were first discovered in 1869 by the Swiss scientist
Friedrich Miescher.

<span>DNA and RNA play
important roles as genetic information carriers in biology, enabling the
mechanisms of heredity and protein synthesis. Nucleic acids are
polymers of nucleotides, which are composed of a five-carbon sugar, also
called a pentose sugar, a nitrogenous base and a phosphate group. The
sugar is deoxyribose, in the case of DNA, and ribose, in the case of
RNA.</span>
Answer A
I believe the correct answer is choice A because an archeologist would know about the houses people built at the site and an anthropologist would know about the river system. I hope this helps :)
