Answer:
ATP synthase utilizes energy of the proton gradient to attach phosphate groups to ADP.
Explanation:
ATP synthase is an enzyme that requires some form of energy to form energy storing molecule ATP, from adenosine diphosphate (ADP) and inorganic phosphate (Pi). Because of that, ATP synthesis is coupled with cellular respiration and electrochemical gradient created by the difference in proton (H+) concentration across the mitochondrial membrane during the transport of electrons through the electron transport chain. In plants, proton gradient is formed in chloroplast, in the thylakoid lumen through the thylakoid membrane.

Explanation:
Cells combined make the tissue,
Tissues combined make the organelle,
Organelles combined make the organ,
Organs combined make the organ system.
Answer:
4x + 6y = 420
Explanation:
since x is number of child tickets and y is adult tickets, and $4 is the cost of child tickets and $6 is the cost of adult tickets, that eliminates A and D.
The question also states "for one day", so that elimates C, which C is the equation for two days.
This leaves 4x + 6y = 420
An injection of weakened bacteria that creates immunity to a disease.
Option c is the correct answer
