Active transport moves small molecules against the a concentration gradient which is the opposite of diffusion or that's what i found in Quizlet
Answer:
C. CALVIN CYCLE(LIGHT INDEPENDENT REACTIONS OF PHOTOSYNTHESIS.
Explanation:
Photosynthesis is the process whereby green plants manufacture their food (organic matters in form of glucose) from carbon IV oxide and water molecules in the presence of sunlight.
The glucose formed undergoes two purposes; provision of energy and in the fixing of carbon.
This process involved two steps : The light dependent process and the light independent (Calvin cycle).
The light dependent reaction takes place in the thylakoid membrane and requires supply of light energy.
ATP and NADPH are formed, water molecules are also formed.
The light independent reaction occurs in the stoma and does not require light energy. The process used the ATP and NADPH formed from the light dependent reaction to fix carbon and produce three carbon sugars.
So the Calvin cycle light independent reaction is involved in the fixing of carbon molecules into organic molecules in the absence of sunlight and the ATP and NADPH formed from the light dependent process of photosynthesis.
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:
C. Document the number of honey-making bees per hive.
Explanation:
Among the given options, the only useful criteria towards the experimental design of honey production are to "document the number of honey-making bees per hive". We know that the increased number of animals would increase the workforce and thus increase the production of honey (direct relation). Therefore, this will give a direct assessment of honey production.
