The moon’s pull on the tides

The rotation of the Earth every 24 hours

The Earth’s orbit around the sun every 365 days

#4. Science Experiment/variables in an experiment: An experiment for a new drug used mice to test its effectiveness. Group 1 consisting of 12 mice were given an injection of 1 mg of the new drug. Group 2 consisting of 12 mice were given an injection of a placebo. Group 3 consisting of 12 mice were not given any injection. Which of the following is the control group in the experiment?

Group 1

Group 2

Group 3

None of the above

#5. Science graph/image interpretation: Which of the following does this image represent?

Newton’s Second Law

The Krebs Cycle

Newton’s Third Law

Evolution

#6. Science reading section interpretation: What is Eutrophication? It’s a problem that should matter to you, whether you live near the ocean or not. That’s because it begins wherever people live and ends with damage to resources we all use and enjoy.It all starts when nutrients get into lakes and oceans. Remember, what’s waste to humans can be food to plants and other creatures. Nutrients feed algae, like they do other plants. Algae grows and blocks sunlight. Plants die without sunlight. Eventually, the algae dies too. Bacteria digest the dead plants, using up remaining oxygen, and giving off carbon dioxide. If they can’t swim away, fish and other wildlife become unhealthy, or die without oxygen. But it doesn’t have to be this way. Protecting marine resources starts with sound agricultural and waste management practices. What is the cause of eutrophication?

Algae growing and blocking sunlight

Fish that are unable to swim away

Plants dying without sunlight

Agricultural waste getting into lakes and oceans

#7. Genetics: Brown eye color is a dominant trait, while blue and green eye colors are a recessive trait. Which of the following terms describes how there can be more than one type of eye color in humans?

Allele

Phenotype

Punnett Square

Meiosis

#8. Physics: Work is defined as:

Two forces acting upon each other

The sum of time and distance

The product of force and distance

None of the above

#9. Scientific Method: What is the difference between a theory and a hypothesis?

A theory is a thoroughly tested and widely accepted fact; a hypothesis is the results of an experiment.

There is no difference between them

A theory is a widely accepted answer to a natural phenomenon supported by data; a hypothesis is an educated guess on how an experiment will end.

None of the above

#10. Chemistry: Which of the following demonstrates a decomposition reaction?

CaCO3 → CaO + CO2

NaCl + AgF → NaF + AgCl

8 Fe + S8 → 8 FeS

2K + 2H2O → 2KOH + H2
