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)
Answer:
right ventricle to left ventricle
Explanation:
A.
conserve energy
The smaller muscle mass of the sloth, means that it needs less energy to work, allowing it to be able to survive on a less diet.
Most of their muscles are concentrated in their upper body, allowing them to be efficient climbers but very slow on the ground.
Answer: Earthworms and gorillas.
