Answer:
A.
Explanation:
The correct sequencing of DNA nucleotides to match A, T, T, G, C is T, A, A, C, G because the nucleotide matches are: Adenine-Thymine, and Guanine-Cytosine. This works both ways, A-T or T-A, and G-C or C-G. The correct sequence therefore is A.
Aerobic respiration happens in the mitochondrion of eukaryotic cells.
Anaerobic respiration does not use oxygen gas and happens in one process after glycolysis called Fermentation.
The process used to make beer would be a kind of fermentation, Alcohol fermentation, I believe.
Answer:
The correct answer is the endocrine system.
Explanation:
The sympathetic division of the autonomic nervous system and the endocrine system are the two prime systems that take part in the stress response.
At the time of acute or chronic stress, the endocrine system first makes the hypothalamus to discharge CRH or corticotropin-releasing hormone into the bloodstream. The release of CRH further makes the anterior pituitary to discharge ACTH or adrenocorticotropic hormone into the blood. This further stimulates the adrenal cortex to discharge cortisol, that is, one of the glucocorticoid hormone into the bloodstream.
The cortisol finally makes the organs and tissues present within the body to effectively cope up with the initial stress stimulus.

Genetic stability maintenance requires an extremely accurate mechanism for DNA replication and mechanisms for fixing the several accidental lesions that occur continually in DNA. Spontaneous changes in DNA are temporary due to immediate correction process called DNA repair. DNA repair’s importance is very evident from the huge investment that cells form in DNA repair enzymes. In 1000 accidental base changes in DNA , fewer than one results in a permanent mutation due to the efficient elimination by the DNA repair.<span> </span>
