A scientist helps a colleague do a better experiment by:
Virty [35]

Answer:

B. Offering advice about how best to perform a standard procedure.

Explanation:

Helping others can be in different ways, be it helping out or by giving encouraging words or advice. But in all aspects of help, there is always a positive outcome if help is given in the right way and at the right time. And it is also how one person lifts another.

A scientist can help a colleague out by offering advice and telling the person how to best perform a standard procedure. This will help the colleague do better in the experiment and also help ensure that the right things are done and the efforts are successful. The other options are all negative in their 'approach' which will only hinder the colleague in his/her works.

Thus, the correct answer is option B.

These two energy-storing molecules are then used in the light-independent reactions.
