The answer is A. Rabbits eat grass. The snakes eat the rabbits and the hawks eat the snakes. So if rabbits died off, so would the snakes, and the hawks. Because both of their food sources would deplete. And grass would flourish.
The question that could be investigated through scientific research is B. Does a newly synthesized chemical reduce bacteria? The answer is B. Because the other questions aren’t science questions. They are bias.
The solution in the berzelius glass has a concentration of 50%, the other solution has a concentration of 30%. In osmosis water moves from the solution with a lower concentration to the solution with the higher concentration. Therefore, water will move from the 5%glucose,25%starch solution to the 20%glucose, 20%K⁺,10% iodine.
Probably water. Abiotic means not living, such as sunlight or water.
