Question

you have been asked by a colleague to determine if a newly developed compound is harmful to living organisms. if species is not a consideration, what would be the best model organism to use, and why?
bacteria, because they are easier to kill.
bacteria, because they grow rapidly and are easily handled.
mice, because they are easier to observe.
mice, because they are mammals like us.

Explanation:

Bacteria grow rapidly, which allows for quick assessment of the compound's effects. They are also easily handled in a laboratory setting, making them a practical choice for initial testing when species - specific considerations are not a factor. Mice, while mammals, are more complex to handle, require more resources, and have a longer generation time compared to bacteria. The reason "bacteria are easier to kill" is not a valid scientific reason for choosing them as a model organism for determining harmfulness.

Answer:

Bacteria, because they grow rapidly and are easily handled.
