Question

Which of the following statements is false about model organisms?

1) should be easy to take care of.
2) should, as closely as possible, represent the system you are interested in studying
3) are cheaper to maintain in the lab than more complex organisms
4) can help relieve some of the ethical concerns of research on more complex organisms
5) None of the above statements is false

Answer 1

Model organisms are chosen for being easier to take care of, cost-effective to maintain, and for reducing ethical concerns. They should reflect the system being studied and can provide valuable biological insights. The provided statements about model organisms are all true.

Step-by-step explanation:

The statement that is false about model organisms is not provided in the list, as all the listed statements are generally true about model organisms:

1. Model organisms should be easy to take care of.
2. Model organisms should, as closely as possible, represent the system you are interested in studying.
3. Model organisms are cheaper to maintain in the lab than more complex organisms.
4. Model organisms can help relieve some of the ethical concerns of research on more complex organisms.
5. None of the above statements is false.

Each of these points is generally accurate regarding model organisms. They are indeed chosen for ease of care, lower maintenance cost, ethical considerations, and their potential to represent the biological systems under study. They help researchers understand complex biological phenomena by providing a simpler, more controllable context for study, often enabling insights that can be applied to more complex organisms, including humans.
