Answer:
Density = Mass/Volume
Density = 216cm3/64g
Density = 3.375 g/cm3
Let me know if this helps!
Answer:
The factors which remained constant are as follows -
- material used as the membrane
- amount of substances used
- number of trials
The factors which have shown variation are as follows -
- molecule size (large starch molecules vs. small glucose molecules)
- whether the molecules diffused through the membrane (tubing)
Explanation
Some factors with in the experiments remained constant from the point of starting of the experiment to its end. While some factors were varied to study its impact on the experiment rate of progression or on the final product formed. Thus , out of the following given factors, the ones that remained constant are -
- material used as the membrane
- amount of substances used
- number of trials
The factors which have shown variation are as follows -
- molecule size (large starch molecules vs. small glucose molecules)
- whether the molecules diffused through the membrane (tubing)
The first one since your doing on the whole neighborhood and not just that one location. You need find the average soil quality and so you need to sample 10 different locations in that neighborhood.
Clouds are made up of tiny drops of water or ice crystals that settle in dust particles in the atmosphere.
