A control can be best defined as:
a variable that is kept constant in an experiment.
an experiment where the final results are known ahead of time.
a hypothesis that regulates the results of an experiment.
a variable that changes during the course of an experiment.

the scientific method
A marine biologist is testing the hypothesis that cold water promotes the growth of corals. Which of the following study designs may yield the most conclusive results?
Two study sites with stable differing water temperatures, similar water nutrient profiles, and similar coral communities growing at different depths
Two study sites with fluctuating water temperatures, similar coral communities growing at similar depths, with similar water nutrient profiles
Two study sites with stable differing water temperatures, similar coral communities growing at similar depths, and differing water nutrient profiles
Two study sites with stable differing water temperatures, similar coral communities growing at similar depths, with similar water nutrient profiles
Oceanographers generally study organisms:
from an organismal perspective.
by incorporating many disciplines in their studies.
farther offshore.
both from an organismal perspective and by incorporating many disciplines in their studies.
These were created to study living marine organisms and conduct long-term experiments.
scientific vessels
remotely operated vehicles
marine laboratories and stations
scuba gear
The ocean is the last mostly unexplored region of Earth, in part because it is so difficult to study organisms underwater. To study marine life at depth, scientists take advantage of all of these tools except:
Satellites.
remotely operated vehicles.
scuba.
Sonar.
Which of the following is not a part of the scientific method?
Relying on objective observation
Peer review
Considering differing hypotheses
Operating on testable hypotheses
Why is reproducibility of a study important?
To allow other researchers to copy the research
To allow another researcher to learn from the study
To slow down scientific progress
To ensure that the results are not false

Photosynthesis
Respiration
Echolocation
Seismology
A marine scientist studying two different sites observes that the species of coral grows much faster in colder water and concludes that the coral is better suited to colder environments. A second scientist is skeptical about these conclusions. What is a legitimate basis for this skepticism?
The first scientist is younger than the second scientist
The second scientist has only studied warm water corals
The first scientist failed to consider variables other than temperature
Both scientists dislike each other
