The domain Eukarya includes all of the following except
Archaea
Which of the following questions cannot be answered by means of the hypothetico-deductive method?
Are red roses more beautiful than yellow roses?
Who is credited with founding the scientific method?
Francis Bacon
A scientist wishes to test a new antibiotic's ability to treat stubborn bacterial infections. He tests his hypothesis that the antibiotic works better than existing treatments by giving bacterial infections to mice and treating them with the antibiotic. He then determines how many of the mice recover from their infections. What is missing from his experimental design?
He is missing a control group of mice that did not receive the new antibiotic.
Which of the following statements represents a scientific point of view?
Testing the effect of antibiotics on E. coli can help prevent deaths from food poisoning.
A scientist observes that when she opens the back door of her house to let her cat out, the songs of a certain species of bird abruptly change. She wants to follow up on her observations with an informal experiment. Which of the following is the best hypothesis for explaining the birds' song changes?
The bird species switches from song to warning call whenever it sees a potential predator.
A scientist believes that she has found a new life form. Which of the following conditions is not considered essential in determining whether the putative new life form is alive?
The creature's body is bilaterally symmetrical.
Which of the following is not a feature of scientific hypotheses?
They are unable to be falsified.
Overfishing of the western bluefin tuna in the Gulf of Mexico breeding ground resulted in a serious decline in the population. Fishing quotas were established in the Gulf of Mexico to allow the endangered population to recover. Why did this policy fail to achieve the desired result?
Western and eastern populations of bluefin feed throughout the entire North Atlantic.
Science is a tool, but has specific limits. Which of the following issues is not able to be addressed by science?

The advantage of controlled experiments is that
all variables are held constant except for one.
Why are theories stronger and more reliable than hypotheses?
because they are based on many experimentally tested hypotheses

An "educated guess" as to what causes an observed phenomenon is known as a:
hypothesis
Biologists have organized the diversity of life into three domains based largely on
molecular data.
Which of the following lists correctly presents levels of organization from simplest to most complex?
