Answer:
Substance C
Explanation:
From the statement scenario, it is given that no water remained above substance C. This then means that substance C actually absorbed all the water above it faster than the two other substances.
Therefore, we can deduce that substance C has the greatest porosity. This means that it has the highest amount of spaces within where the water can be absorbed.
Porosity has to do with the available empty spaces which is within a material. This property allows materials or substances to absorb other substances that are absorbable.
Valves ensure blood flows toward your heart. Vein valves work to bring the blood that flowed down via arteries back up to your heart.
Answer: False
Reason: We Use Minerals In our day to day life, when it comes to cooking, or burning. We use Salt to cook amazing meals, and some pots and pans have minerals built in to them so that they last longer over the years you cook with them. When we burn in the fireplace or in the backyard, some of us use coal and light it up, and sometimes, we use minerals to make buildings. In one of my neighboring towns, their City Hall has little mineral pieces built into the City Hall. I hope this helps, and happy holidays! :)
