Clinical trials are restricted by ethics because they involve human patients.

B. It involves a human patient

<u>Explanation:</u>

A human life  is much more than just a body to be studied under various conditions. Humans are social  animals and need to socialize, breathe in fresh air, have a nutritious and balanced diet  and a sound sleep in order to live a fruitful life.

Clinical trials are the types of research in which people participate as subjects or hosts  in order to test new treatments, effects and various medical conditions.

Some people also  volunteer to test how certain external conditions effect human body. They are kept in the  conditions which are to be tested for numerous days.

Answer:

It involves a human patient. Because of concerns such as dignity, human rights and political correctness, the term <em>"patient" </em>is not always used to refer to a person receiving health care.

Why is scientific knowledge more reliable than other types of knowledge?
RUDIKE [14]

Answer:

D. Because science only uses facts that are proven 100% true through the use of  variables.

Explanation:

All the knowledge we read is science books are not merely some observed facts but the result of a systematic scientific methodology through which facts are tested. Science only gives us that knowledge as facts which is  proven 100% true through the use of  variables.For example: if a scientist has studied the effect of salt stress on the growth of plants and he got the results in form of graphs which show that growth of salt treated plants in very less than normal plants. Then he needs to draw conclusion after consulting relevant previous experiments and say that salt stress hinders growth and why? with reasonable logic.

Variables are the things hat he changes like environmental conditions in previous example to see that in changed conditions plant is showing changed behavior. This way a scientist strengthens his results. Therefore, we can say that whatever knowledge we get through science is proven 100% true through the use of  variables.

Hope it helps!
