Multiple choice

You're a scientist working on a breakthrough medical treatment. However, the treatment requires testing on animals, potentially causing them pain and suffering. Do you:

  1. Proceed with the animal testing, believing the potential benefits outweigh the harm to animals.

  2. Abandon the research, prioritizing the well-being of animals over scientific progress.

  3. Seek alternative methods or collaborate with animal welfare organizations to minimize animal suffering during testing.

C Correct answer
Explanation

Striving to minimize harm to animals while pursuing scientific advancements is the most ethical approach. Exploring alternative methods or collaborating with animal welfare organizations can help reduce animal suffering during testing.

Multiple choice

What is the main advantage of using induced pluripotent stem cells (iPSCs) over embryonic stem cells?

  1. They are more readily available.

  2. They have a lower risk of immune rejection.

  3. They are more ethical to obtain.

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

iPSCs are generated from a patient's own cells, eliminating the ethical concerns associated with embryonic stem cells. They are also less likely to be rejected by the patient's immune system and are more readily available.

Multiple choice

Which disease has been successfully treated using stem cell therapy?

  1. Parkinson's disease

  2. Alzheimer's disease

  3. Type 1 diabetes

  4. Multiple sclerosis

C Correct answer
Explanation

Stem cell therapy has shown promise in treating type 1 diabetes by replacing damaged insulin-producing cells in the pancreas.

Multiple choice

What is the primary ethical concern associated with embryonic stem cell research?

  1. The destruction of embryos

  2. The potential for genetic manipulation

  3. The risk of immune rejection

  4. The high cost of treatment
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The primary ethical concern with embryonic stem cell research is the destruction of embryos, which some people believe is morally wrong.
