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:
Saputara Hill Station
Explanation:
Located atop a thickly forested plateau in the Sahyadri range, Saputara is the only hill station in the Dang district in the south of Gujarat.
Answer:
true
Explanation:
because the energy that comes from burning fossil fuels is converted into electricity and heat in power plants. When fossils are burned, carbon and hydrogen react with oxygen to produce carbon dioxide (CO2) and water (H2O) during this reaction heat is produced
C) its protein synthesis. any thing that has to do with proteins are ribosome. not lipids.
Answer:
Type of liquid
Explanation:
Daniela wanted to figure out what type of liquid worked best for growing beans. She watered one with coca-cola, one with lemonade, and one with just water. After one week, she measured how high they had grown. What is the independent variable?
Answer: An independent variable is a variable that does not depend on any other variable (it is the input variable) while a dependent variable is a variable that depends on other variable (it is the output variable).
In this question the two variables are the height of the plant after a week and the type of liquid used. Since the height of the beans depend on the type of liquid, therefore the height of the beans is the dependent variable while the type of liquid is the independent variable.
