Fruit flies are commonly used in genetic investigations that focus on traits passed from parents to offspring over several generations. what can you infer is the reason fruit flies are the most commonly used organism for this type of investigation? a. fruit flies are relatively inexpensive b. society does not have ethical issues with lab-kept flies c. many more generations can be studied using short-lived organisms
d. scientists prefer to study what has previously been studied

C. many more generations can be studied using short-lived organisms

Explanation:

Fruit flies are organisms with a shorter lifespan. Their average lifecycle takes about a week to develop from lava to an adult. This characteristic of fruit flies are reason they are used for the genetic investigation.

The genetic characteristics of the organism can be studied over a short time. The accuracy of the study can be increased as there will be more data and statistics related to same experiment.

Long term effect as well as short term effect can be studied easily.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

c. heat from the poles back down towards the equator.
