Observation designed to minimize the effects of variables other than the independent variable.
Answer:
The results are precise but not accurate
Explanation:
Precision is the term that refers to the degree of agreement between measured results. This means that the measurements of the finished system are very similar and with equal differences, under the same conditions.
An example of this is the results shown in the question above, which are very similar. In addition, these results do not have the "real and absolute value" and therefore are not accurate.
Answer: <u>Option B; It traps light energy and converts it into chemical energy.
</u>
This substance is chlorophyll. It is a pigment present in leaves of all plants. It absorbs light energy and provides it to carry out the process of photosynthesis. Light energy is converted into chemical energy, in form of NADPH and ATP, which can be used by plants for photosynthesis.
This pigment is present only in plants, so option A is incorrect.
This pigment only absorbs and transfers energy to other molecules, and is not associated with carbon dioxide directly, so option C and D are also incorrect.
