Answer:

A. Includes at least two groups, one of which does not receive the experimental treatment

Explanation:

A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.

Also, an experimental group can be defined as a collection of participants that are subjected to the independent variable.

Generally, most scientific experiments usually have a control group so as to avail the scientists (experimentalists) an ability to compare the outcome of their test results. This control group is not given the treatment or influenced by the same independent variable as the experimental group.

Therefore, this is the reason why science completely or totally rejects any hypothesis which is not supported by observations, as well as the results obtained from control experiments.

This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.

Hence, a controlled experiment includes at least two groups, one of which does not receive the experimental treatment.

Answer:

1.Carbon dioxide is converted to sugar used for food. - 1. Location- A

2.Carbon trapped in fossil fuels is converted to carbon dioxide. - 2. Location- C

3.Organic carbon is converted to fossil fuels. -3. Location- E

4.Carbon dioxide is converted to carbonates.- 4. Location- D  

5.Sugar is broken down and converted to carbon dioxide.  - 5. Location- F

Explanation

1. Carbon dioxide is converted to sugar used for food: The carbon dioxide is converted into sugars by the process of photosynthesis, which occurs in the green plants. Plants trap carbon dioxide and sunlight from the atmosphere, to synthesize their food.

2. Carbon trapped in fossil fuels is converted to carbon dioxide: The fossil fuel produced deep inside the earth, acquired by the factory. From the factory the carbon dioxide liberated to the atmosphere.

3. Organic carbon is converted to fossil fuels: The organic carbon obtained after the degradation of organic matter is responsible for the synthesis of fossil fuels.

4. Carbon dioxide is converted to carbonates: The carbon dioxide from the atmosphere gets dissolved with water of the water body and termed as carbonic water.

5.Sugar is broken down and converted to carbon dioxide: The glucose or sugar as a source of food in plants gets broken down into carbon dioxide and water by the process of respiration.
