Answer:
Cellular membrane.
Explanation:
In prokaryotes electron transport chain isIn prokaryotes electron transport chain is located in the cell membrane. ETC is defined as the series of complexes which helps in the transfer of electrons from electron donors to electron acceptors via reduction, and oxidation reaction couple the transfer of protons with electron transport across a member.
The primary function of the ETC is generated a transmembrane proton electrochemical gradient, such as oxidation, and reduction reaction.
 
        
             
        
        
        
It would be the nuclear membrane
        
                    
             
        
        
        
Homeostasis refer to the metabolic balance being maintained by several processes. It may include having a stable internal physiologic condition such as the blood ph or body temperature. Among the options, the best answer would be c. the villi of the small intestine would increase the absorption of nutrients from small intestine to the blood.
        
             
        
        
        
Answer:
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP. Hope this helps!

Answer:
It would be A: a cell that has double the number of chromosomes as the parent cell 
and if for some reason that is wrong then it could possibly be C and just use the same explanation.
Explanation:
This is because Haploid Gametes are the things that are produced during meiosis-which is a type of cell division which reduces the number of chromosomes in a parent diploid cell by half
