Negative feedback, because sweating can decrease body temperature.
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.

The abiotic factor that is essential for all aquatic ecosystem with the exception of hydro thermal vent is SUNLIGHT, THIS IS BECAUSE IT PROVIDES A SOURCE OF ENERGY.
Sunlight is very essential for aquatic ecosystems because it is the principal source of energy from which aquatic plants trap energy to make their food and provided mean of sustenance for themselves and other organisms in the water.
Answer:
A catalyst
Explanation:
Enzymes are not a catlysy
At the molecular level, the heat comes from the agitation of the molecules and therefore their atoms. This increase in agitation causes the molecules to be less condensed between them and will separate after breaks in the intermlecular bonds. This distends the material, as we see when we heat a metal, or a transformation of the phase of the material, such as melting ice or boiling water.
