1. homeostasis
2. negative feedback loop
3. the hypothalamus
4. the body’s optimal temperature, which is 37 degrees C, or 98.6 F
5. humans are endothermic, which means they don’t completely rely on their environment for heat, unlike ectothermic organisms such as reptiles. the diagram shows that the brain is in control of the body’s temperature, and that the body can raise its own temperature in its blood.
or something like that, hope this helped
Answer:
Solar energy, Wind energy, Geothermal energy, Hydroelectric energy.
Explanation:
Have a nice day!
<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
Precision refers to the closeness of two or more measurements to each other.
For Example: If you weigh a given substance five times and you get 3.2 kg each time. Then the measurement is very precise.
Accuracy refers to the closeness of a measured value to a standard or known value.
For Example: If the mass of a substance is 32 kg and one person weighed 31 kg and another person weighed 29 kg. Then, the weight measured by first person is more accurate.
According to the question:
Mass weighed by Mary = 10.00 g
Mass weighed by Tommy = 10 g
As, mass weighed by Mary is reported upto 2 decimal places. Thus, it is more precise.
Hence, the correct answer is Option C.
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.
