Yes, If there were no concentration gradient of protons across the thylakoid membrane, the ATP synthase would not be able to convert ADP to ATP.
The molecule will enter the cell using a channel protein.
Answer:
Equal amounts of DNA contain equal proportions of nitrogenous bases.
Explanation:
According to Chargaff's rule, the nitrogenous base pairs (Purines and pyrimidines) have an equal ratio (1:1) in the DNA of all the organisms. More precisely, the amount of adenine is equal to thymine and the amount of guanine is equal to cytosine in the DNA of all the organism. A-T base pair has two H-bonds while G-C base pair has three H-bonds.
1. plants do not need and complex excretory organ because it creates a very small amount or nitrogenous waste.
