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.

Antibiotics are, initially, molecules naturally synthesized by microorganisms to fight against bacteria competing with their environment. This created a pressure of selection on the bacterial populations, leading to the appearance of resistant strains. In fact, when an antibiotic is used, only bacteria with defense systems against this molecule survive (and reproduce).

The answer is A. cleavage, differentiation, fertilization, gastralution
soil, rock, organic layer
Explanation:
Permeability is the ability of a layer of rock to transmit fluid such as oil or water
The factors that affect the permeability of a rock layer includes the sizes of the rock particles, the ratio of the available voids to the solid mass of the rock, the presence of trapped air and the presence of organic matter
Rocks such as gravels, and sparingly cemented sands have high permeability
The most impermeable of the options are granite and clay which for granite has large particle mass and contain no voids while clay has very fine particles packed together with little room for water
Therefore, water moves easily between layers soil, rock, organic layer
Answer:
c. accidental removal of the parathyroid glands during surgery
Explanation:
Parathyroid gland is found closely situated at the back of the thyroid gland in the human neck region. Regulation of serum calcium levels in the body is a major function of the parathyroid gland through the secretion of a hormone called parathyroid hormone or parathormone.
During the surgery conducted to remove the thyroid gland, it is very likely that the parathyroid glands were accidentally damaged or removed. This most likely led to the non--secretion of parathormone, which is responsible for secretion of calcium in the body, when calcium levels drop.
