Answer:
In science a hypothesis is useful only if it can be <u><em>tested</em></u>.
Explanation:
In a scientific experiment, a hypothesis can be described as a tentative experiment that can be tested through observations and experimentation. The results inferred from the experiments can prove whether a hypothesis was correct or wrong. Hence, a hypothesis is a very important part for the scientific method of research. The validation of a hypothesis through experimentation brings about theories, facts, laws etc. A hypothesis is made in response to a scientific question.
Answer:
B would be the correct answer
Explanation:
Well the answer is obvious, but since it's biology lets fill this out with punnet squares. fill the punnet square with 'rr' and cross it with 'rr' since both of Marcus and Olivia can't roll their tounge. when you do cross it you'll get 'rr' which also means their childeren won't be able to roll their tounge. I hope this helped, i'm not very good at explaing things :)
