Viruses are not cells; they are a strand of genetic material within a protective protein coat called a capsid. They infect a wide variety of organisms, including both eukaryotes and prokaryotes. Once inside the cell, they use the cell's ATP, ribosomes, enzymes, and other cellular parts to replicate.
Answer: Observable properties
Explanation:
The statement above is TRUE.
The electrochemical gradient in the chloroplast is a gradient of electrochemical potential of ions which move across the membrane of the chloroplast during the photosynthesis process. The proton gradient across the thylakoid membrane drives the ATP synthesis during photosynthesis.
