Answer:
Natural selection
Explanation:
Adaptation deals with organisms becoming more suited for their environment. It does not directly determine survival and reproduction.
Artificial selection is caused by humans. Therefore, adaptability may not play a role in this selection.
Natural selection is caused directly through adaptability. It results in organisms reproducing if they are capable of survival. Organisms that cannot adapt do not survive.

Answer:
The time taken for the reaction to go to completion(time taken for the cross to disappear) decreases steadily down the column for time.
Explanation:
If we look at the table closely we would quickly observe the following;
1) the volume of HCl was held constant
2) the volume of sodium thiosulphate was increased steadily
3) the volume of water was decreased steadily
The increase in volume of thiosulphate and decrease in the volume of water meant that reactant concentration was increased steadily. From our knowledge of factors that affect the rate of reaction, we know that the rate of reaction (typically read off as time taken for a given reaction to go to completion, in this case, decrease in the time taken for the cross to disappear) increases with increase in concentration of reactants.
Hence it is expected that as the concentration of reactants increase, the rate of reaction increases. As the rate of reaction increases, the time taken for the cross to disappear decreases. Hence the answer above.
Answer:
I'm not 100% sure but I think it would be constant

Explanation:
Recycling paper helps to reduce greenhouse gas emissions that can contribute to climate change. It takes 70% less energy and water to recycle paper than to create new paper from trees. Manufacturing with recovered paper cuts down on pollution that contributes to smog (and ill health).
