Answer:
In the experiment conducted by Alisha to test the effect of different materials on the melting rate of ice, the dependent variable is the mass of the ice, and the independent variable is the type of cover material.
Explanation:
During an investigation or experiment, the dependent variable is the one whose changes will be studied, while the independent variable is able to influence the changes of the dependent variable.
In the case where it is wanted to <u>measure how different cover materials affect the rate of ice melting</u>, the dependent variable is the mass of ice and the independent variable is the coverage material, capable of affecting the time it takes for the ice to melt.

The cell theory was developed in 1665 and the microscope in 1590
The characteristics of the cell membrane that determines what gets into a cell and what doesn't is the properties of the phospholipid bilayer and its proteins.
They would be further apart than a solid and they would be closer together than a gas.
Starch/glucose is the food prepared during photosynthesis. if a plant has photosynthesised, it means it has produced its products. you can check this by doing the starch test. boil the leaf which will kill the cells and then dip it in ethanol to extract the green colour. then add the iodine. if the leaf turns blue/black after adding the iodine, this means starch is present and starch is the extra glucose produced (product)
