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.

The rate of heat production is increased by increasing muscle contraction by movement is: Shivering thermogenesis Non- Shivering
vesna_86 [32]

Answer:

Shivering thermogenesis.

Explanation:

The rate of heat production is increased by increasing muscle contraction by movement is shivering thermogenesis because nerve impulses are transmitted to the skeletal muscles by the hypothalamus which will result to contractions that will produce heat.

Shivering thermogenesis is Contraction-mediated heat production High intensity shivering activates large muscles and produce more glycolysis which is then use as the main source for heat production
