He is making a plant cell since the cell walls are box shaped, the balloon would be the large vacuole which takes up a lot of space in the cell, the marbles would be the ribosomes.
Because carbon dioxide is a GREENHOUSE GAS, it can trap the sun's heat in the atmosphere. Because the factory is made of concrete, it may deplete groundwater levels over time by not allowing water to INFILTRATE.
Greenhouse gases (GHGs) are gaseous components that absorb the infrared radiation emitted by the earth's surface and contribute to the greenhouse effect. The increase in their concentration in the Earth's atmosphere is one of the factors causing global warming.
Concrete does not allow water from the ground surface to infiltrate to underground.
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.
