Explanation:
Blood pressure regulation is an example of negative feedback mechanism. When the blood pressure is low, sensor in the blood vessels called baroreceptors detect this and send a signal to the control center which is the hypothalamus.
The hypothalamus compares the current blood pressure with the normal and proceeds to send signals to the heart, as well as blood vessels and kidneys. The heart begins to beat faster, thereby increasing the heart rate and a a result, blood pressure goes back up to normal.

The correct answer is A. Bases pairs, DNA, Gene, Chromosome, Cell.
Explanation
Nitrogen bases are chemical compounds that compose DNA and RNA, in the case of DNA the bases are adenine, thymine, guanine, and cytosine, while RNA is made up of uracil, adenine, guanine, and cytosine. Additionally, DNA makes up genes, which are structures that store information that is passed on to offspring. Also, genes are organized to form chromosomes (more complex structures) of genetic information. Finally, there are cells, in them are chromosomes, fundamental for the reproduction of an organism. Therefore, the correct answer is A. Bases pairs, DNA, Gene, Chromosome, Cell.
