While taking observations
During hypothesis formulation
During data organization
None of the above

Question 4 of 17

4. Question

A hypothesis must be testable to be scientifically valid. Being testable means that________________.

some observation could prove the hypothesis incorrect
Only a controlled experiment can indicate whether the hypothesis is correct or incorrect
The hypothesis is proven wrong
There must be several options in the hypothesis to choose from, one of which is correct

Tested a hypothesis

Question 7 of 17

7. Question

A scientific theory has which of the following properties?

It agrees with available evidence
It cannot be rejected
It has been absolutely proen
It does not need to be altered in the light of new evidence

Question 8 of 17

8. Question

Experimentation is only a step of the scientific process, but it is a very important step because it always_________________

Gives the biologist a correct result
Allows rejection of some alternative hypotheses
Ensures that hypotheses can be confirmed with certainty
Gives scientists a chance to work in the laboratory
