Answer:
e. PhoU keeps PhoR bound to the phosphate transporter protein Pst
Explanation:
PhoU is a membrane protein known to regulate the transport of phosphate (Pi) between cellular compartments. It has been discovered that mutations in this protein cause lethality because the cell becomes incapable of controlling the intracellular levels of Pi, this being toxic for the cell. PhoR is a histidine kinase/phosphatase. When the Pi level is considered to be a limiting factor, PhoR autophosphorylates at a histidine residue and then donates its phosphoryl group to PhoB. On the other hand, when the Pi level is high, this protein removes the phosphoryl group from phospho-PhoB. Finally, the Pst is a signal transduction protein that acts as a transporter capable of switching its conformation during the transport of PI.
Answer:
dilation of vessels and sweating
Explanation:
The vast blood supply of the skin aids in temperature regulation: dilated vessels enable heat to escape, while constricted vessels retain heat. The blood supply of the skin regulates body temperature. The skin aids in the maintenance of homeostasis. Humidity has an effect on thermoregulation because it reduces perspiration evaporation and, as a result, heat loss.
Explanation:
It is based on the principle of continuous improvement. The standard enables companies to define what a quality product should be and how it should meet customer needs.

What is artery?</h3>
- The blood channels that carry oxygen-rich blood from the heart to the body's tissues are called arteries.
- Each artery consists of three layers and is a muscular tube bordered by smooth tissue.
- The endothelium, a smooth tissue, lines the intima, the inner layer.
- Blood is transported from your heart through arteries.
- All body parts have arteries, with the exception of the hair, nails, epidermis, cartilages, and cornea.
- In the limbs, they run along the flexor surface, where they are less vulnerable to injury, and the larger trunks typically occupy the most protected positions.
- A conduit that carries blood from the heart to the body's extremities is called an artery.
- Every artery, with the exception of the pulmonary artery, carries oxygenated blood.
- The ascending aorta, aortic arch, thoracic aorta, and abdominal aorta are the four divisions of the aorta, which is the biggest artery in the body.
