Identify the dependent and independent variables in the following examples: -The growth of bacterial populations is measured in cold, medium, and high temperatures. -Guinea pigs are kept at different temperatures for 6 weeks. Percent weight gain is recorded. -The diversity of algal species is calculated for a coastal area before and after an oil spill.
Microbial Physiology
Microbial physiology is the branch of microbiology that is associated with studying the physiology of fungi, bacteria, and viruses. It is an important field of science concerning functional genomics and metabolic engineering.
Chemotaxis
The organism’s movement in a particular direction as a response to certain chemicals that are available in the environment is defined as chemotaxis. In brief, it can be defined as the occurrence of an organism’s movement in response to a certain chemical stimulus.
Identify the dependent and independent variables in the following examples:
-The growth of bacterial populations is measured in cold, medium, and high temperatures.
-Guinea pigs are kept at different temperatures for 6 weeks. Percent weight gain is recorded.
-The diversity of algal species is calculated for a coastal area before and after an oil spill.
-Batches of seeds are soaked in salt solutions of different concentrations, and germination is counted for each batch.
-An investigator hypothesizes that the adult weight of a dog is higher when it has fewer littermates.
