Human Biology Chapter 1 quiz with
correct answers.
organisms levels of organization ANS - atoms, molecules, cells, tissues, organs, organ systems,
organisms, populations, community, ecosystem and biosphere.
organisms ANS - take materials and energy from the environment
reproduce
grow and develop
are homeostatic
respond to stimuli
have an evolutionary history and are adapted to a way of life
Humans differ from other mammals by their,... ANS - highly developed brains
completely upright stance
creative language
ability to use a wide variety of tools
Humans are members of the biosphere ANS - Humans depend on the biosphere for its many services,
such as, absorption of pollutants, sources of water and food, prevention of soil erosion, and natural
beauty.
The Scientific method ANS - 1. observation
2. hypothesis
3. experiment/ observations
4. conclusion
5. scientific theory
, How the cause of Ulcers was discovered ANS - Dr. Marshall followed Koch's postulates to show that
Heliobacter pylori causes ulcers. When he was unable to infect an animal with the bacterium, he and
another volunteer infected themselves. His persistence led to clinical studies that showed antibiotics can
cure ulcers.
How to do a controlled study ANS - 1. a large number of subjects are divided randomly into groups;
2. the test group is exposed to an experimental variable;
3. a control group is not exposed to an experimental variable and is given a placebo;
4. all groups are otherwise treated the same, and it is best if the subjects and technicians do not know
what group they are in; and
5. the results and conclusion are published in a scientific journal.
Statistical data ANS - The standard error tells us how uncertain a particular value is. The statistical
significance tells us how trustworthy the results are. The lower the statistical significance, the less likely
the results are due to chance and the more likely they are due to the experimental variable.
The total number of species within the biosphere ANS - biodiversity
A major scientific ____ is dependent on much experimentation ANS - theory
Humans are in the ____ Animalia ANS - kingdom
Species _____ to make offspring ANS - reproduce
A scientific theory in biology that suggests that all organisms arose from earlier forms. ANS - theory of
evolution
What a scientist tests in an experiment ANS - hypothesis
The layer of life surrounding this planet ANS - biosphere
