b) Identify a dependent variable in the experiments. Identify the reasoning of the scientists when they tested the number of col

onies produced by strains C3-PBB and C6-PBB . The scientists also analyzed the number of colonies produced from each of the environmental and clinical isolate strains when the strains were plated on a growth medium lacking the toxic chemical. Justify this analysis.

Answer:

Explanation:

Dependent variable is the outcome that is measured. This is the number of colonies produces by the clinical Isolate strain. Without the growth media the strain cannot thrive or reproduce hence their dependent on the media for survival.

While independent variable is the treatment that is varied in an experiment. It usually not dependent on any variable and can stand on it own.

The growth media that is lacking in chemical is the independent variable because it stands on it own and it can be carried depending on the experimental design it could be a chemical based growth media or no chemical like the one used in this experiment.

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.
