The Fish does not give off Carbon Dioxide
Pretty sure the answer is potassium. Hope that helps:)
Answer: A
The cells would lose water and shrink. In a hypertonic solution, the
concentration of solute is higher than water in a cell. With this, there is a
net movement of water from inside to outside initiating water to lose from the
cytoplasm and vacuole causing the cell to shrink due to osmosis and achieve
equilibrium.
This process is applied in food preservation where microbial cells will
be dehydrated in a hypertonic environment, making them malfunction and preventing
them to cause food spoilage.
Answer: Food can be an obvious answer because people will not survive without food so they will die. And death means there will be a decrease on population size. So food can be a limiting factor that is dependent on population size.
