Trick question. Bacteria do not have cell walls. They barely have cell membranes. The second blank might be either chemosynthetic (break down chemicals for food) or photosynthetic (generate food from sunlight).
Answer:
4 1/4
Explanation:
17/4 = 4/4 + 4/4 + 4/4 + 4/4 + 1/4
4 + 4 = 8
4 + 4 = 8
8+8=16 = 16/4
16/4 + the 1/4 remaining in the equation = 17/4
so 4/4 + 4/4 + 4/4 + 4/4 = 4
4 + 1/4 = 4 1/4
sorry if you couldnt follow along. I am not good at explaining things but the answer is 4 1/4
