it has slim chances to survive between 2 cactes
Gram-positive and Gram-negative are different in their resistance to antibiotics. It is because of their different structure of cell wall. Gram-positive bacteria have a thick peptidoglycan cell wall and dyes purple in the Gram test (for categorization of bacteria). Gram-negative bacteria have thin peptidoglycan layer and do not turn purple. Gram-positive bacteria are easier to kill because their thick peptidoglycan layer absorbs antibiotics.
The correct answer is the first one because we could see reaction 2 has more energy than reaction 3 if you look at the graph and it can't be the second one cause c has more energy than a so the correct one is the first answer
