Answer:
Because humans are multicellular, eukaryotic (contains a nucleus), vertebrates, and mammals, the best organism to test the synthetic hormones on would be a mouse.
Explanation:
Humans and whales are multicellular (they have many cells) and their cells are eukaryotic (contain a nucleus). They also have a backbone (spinal column), which makes them a vertebrate. Finally, all humans and whales are mammals. Therefore, to get the best results, the testing should be performed on a mouse.
- Performing the experiment on yeast would give good results for singular-celled organisms, like <em>protozoa</em>.
- Performing the experiment on a fruit fly would give good results for multicellular invertebrates, like <em>spiders</em>.
- Performing the experiment on zebrafish would give good results for all fish in general.
An independent variable is one that is changed and its effect on the dependent variable is investigated. Examples of experiments involving such variables may be:
Effect of light intensity (independent) on the rate of photosynthesis (dependent)
Effect of temperature (independent) on the rate of a reaction (dependent)
Effect of concentration of reactant (independent) on the rate of a reaction (dependent)
Answer:
When you are in the laboratory and take a direct sniff of the chemicals you are using, you run the risk of damaging your mucous membranes or your lungs. When it is necessary to smell chemicals in the lab, the proper technique is to cup your hand above the container and waft the air toward your face.
