Question 7

Why are scientists moving slowly regarding the therapeutic use of stem cells?

Accepted Answer

All of the given options are reasons why scientists are moving slowly regarding the therapeutic use of stem cells. There are limited sources of stem cells, and countries have not been able to come up with a universal policy for conducting research using stem cells. Additionally, stem cells can migrate from where they were implanted into other tissues of the body, which can cause unintended consequences. These factors have contributed to the cautious approach taken by scientists towards therapeutic use of stem cells.

Question 8

Even flawed theories are useful for scientific progress.

Accepted Answer

Flawed theories may provide a basis for further research and investigation, leading to the development of improved theories and a deeper understanding of the subject matter. They can also help to identify areas where further research and experimentation are needed. Therefore, even if a theory is flawed, it can still be useful for scientific progress.

Question 14

Scientists typically do not speak of final or ultimate truths.

Accepted Answer

Science is an ever-evolving process of inquiry and investigation, and new discoveries and information can lead to changes in understandings and perspectives. Therefore, scientists do not consider their theories or findings to be absolute or ultimate truths. They are always open to revisions or even completely new observations that might challenge or change their theories.

Question 15

One of the success stories of gene therapy is that of treatments for SCID.

Accepted Answer

SCID is a severe combined immunodeficiency disorder that is caused by a genetic mutation. Gene therapy has been successful in treating SCID by introducing a functional copy of the mutated gene into the patient's cells, restoring immune function.
