Answer:
Cortisol
Explanation:
The most important human glucocorticoid is the cortisol. It is also called hydrocortisone or stress hormone. It is produced in the zona fasciculata layer of the adrenal cortex of the adrenal glands. It controls blood sugar level between meals. It helps in maintaining blood pressure by controlling salt and water balance. It also control a response to stress by making more glucose from proteins and fats.
Answer:
404 amino acids
Explanation:
The translation is the process by which a messenger RNA (mRNA) molecule is used as a template to synthesize a protein in the ribosomes. During translation, each triplet of nucleotides or 'codon' determines one specific amino acid of the growing polypeptide chain (i.e., the protein). In this case, the length of the fully processed AURKA mRNA consists of 1,212 nucleotides, thereby the length of the polypeptide chain will be 404 amino acids (protein length = 1,212 / 3 = 404 amino acids).
B, C, D
Meiosis is for sexual reproduction and is meant to create diversity. Answers A/e involve identical-ness, so they are wrong.
Answer:
E. that area of the membrane is in the absolutely refractory period.
Explanation:
Refractory period is a period during which neuron cell cannot be stimulated (depolarized). This is why the action potential can only travel in one direction from the neuron body towards axon.
Refractory period occurs because of the inactivation of voltage-gated sodium channels (while action potential is at its peak) which cannot be open for a certain period of time. and membrane cannot be depolarized.
