A group of students wants to study the structures of animals in the desert. One question they should ask is-

Brrunno [24]

From studies and research, I believe the proper question would be:

"How do the animals satisfy their need for water?" or "How long do the animals live?"

Explanation 1:

When studying the desert, asking "Can you buy the animals in pet stores?" is not going to help you find information about the desert because it is not a question to get information about the desert, only information if you just buy it at your local pet shop.

Explanation 2:

Asking "How many offspring do the animals have?" does help us learn about animals, but we are trying to find information on the structure of the desert in which the animals live in. We are not looking for how many children the animals will have because it doesn't fully relate to the question we would be asking.

Side Note: Offsprings mean children.

When doing medical research with human subjects, which four limitations are un voidable?

viva [34]

The four limitations are

1.It's often impossible to repeat trials on the same subjects.

2-Subjects may report an inaccurate medical history.

3-It can be difficult to control all possible variables.

4-It's impossible to come up with testable scientific questions for human subjects.

Research involving human beings is ultimately necessary for improvements in human health and welfare. Any results about healthy physiology, illness causes, treatment effectiveness, learning, or behavior must be verified by carefully controlled investigations involving human participants. Sadly, not all human research have been valid and beneficial. It is possible to harm people in the name of research. The most well-known instances happened in Nazi Germany. Investigations conducted after the war found several crimes, including experiments in which participants were submerged in extremely cold water to determine how long it would take them to pass away from hypothermia.
