<span> Very inefficient. Almost 90% of all energy is lost between trophic levels. That is why larger animals need to eat more, because less energy is being consumed.

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.
Need a better picture!! it’s really blurry and can barely read
Answer:
A 40 percent
Explanation:
If guanine is 10 percent this means that cytosine will also be 10.thats a total of 20 percent. We will then have 80 percent remaining for thymine and adenine. As we know adenine make a bond with thymine so 80 divide by 2 is 40 percent for each
