Answer:

Letter d. Evola virus could not produce an exotoxin

Viruses are acellular particles carrying genetic material only for their reproduction. None of the viruses produces toxins, viruses atack by altering the normal function of the host cell. In the other hand, bacteria involve in alimentary infections like <em>E. coli, S. aureus</em> and <em>C. botulinum</em> produce exotoxins to attack the host cells to colonize and start an infection.

Anuta_ua [19.1K]

Her hypothalamus will secrete vasopressin. If her dehydration becomes severe, her secretion of vasopressin will increase.

<h3>What is vasopressin?</h3>
  • The posterior pituitary gland releases the peptide hormone vasopressin, also known as antidiuretic hormone.
  • Which is produced by the supraoptic and paraventricular nuclei of the hypothalamus (neurohypophysis).
  • It primarily functions as an anti-diuretic in the kidney, where it causes the body to reabsorb water by acting on the distal region of the nephron when it is dehydrated.
  • The AVP gene for it is found on human chromosome 20.
  • Vasopressin has an antidiuretic effect; it reduces the volume of urine by raising the collecting tube's water permeability.
  • It attaches to the G protein-coupled V2 receptor, which in turn starts a signaling cascade through the PKA.
  • Aquaporin 2 (a transmembrane pore) is produced as a result, and it is then transported to the apical/urinary membrane.
