Answer:
She could time how long it takes for each amount of salt dissolves in the waters. (as well as keep each amount of salt the same if she was not doing that already.)
Explanation:
This way, she could observe which water is best for dissolving solvents and which is most affective in the shortest amount of time. If she was not timing how long it takes for salt to dissolve in different temperatures of water, then the experiment may as well have been useless unless there is somehow a different objective.
Some of the aspects that help you determine whether a study is rigorous are questions and hypotheses that can be answered, adequated method use, and bibliography.
Rigorous is a term that refers to a quality that focuses on accuracy and precision to comply with norms, precepts, and pre-established rules. This term is widely used in science to refer to the precision of a study or investigation.
Therefore, when it is established that a study is rigorous, its attributes must be taken into account, such as:
- Questions and hypotheses that can be answered: This aspect refers to the investigator having the ability to limit his study so that it is appropriate to do so and does not include too much information that makes his study "impossible".
- Adequated methods use: This refers to using the appropriate methods to reach feasible conclusions, for example, methods of observation, deduction, induction, among others.
- Bibliography: This refers to the research or study being supported by reliable sources so that it is as accurate as the information it provides.

<span>Many planets are made of gas, and in different situations, the atmosphere can be destroyed.
The sun which is burnt measures atmosphere and in the same case planets can be in a good situation on galactic map and a great condition in the atmosphere as well as earth.
For example, the mass of an object can attract a smaller object causing gravity. The bigger the masses of a planet when it is in the right condition the more atmosphere it can attract if there is any floating on the planet. If it is big it will make a gravitational influence and gather more gases.</span>
Answer: Image D has the most direct sunlight
Explanation:
Since direct sunlight is supposed to be intense, it can't be B or C. Sunlight is most intense in summe, so winter and fall are out. Now we have A and D left. The sun is illustrated in image D and the area the sun covers is larger than image A's, so image D has the most direct sunlight.
