and Bacteria.
Fungi are classified into which Domain? - Correct Answers -Eukarya
There is (are) _____ eukaryotic domain(s). - Correct Answers -One
A single-celled eukaryotic organism that is neither a consumer nor a decomposer would
most likely be classified in _____. - Correct Answers -one of the kingdoms of Protista
Which statement is not consistent with Darwin's theory of natural selection? - Correct
Answers -Individual organisms experience genetic change during their life spans to
better fit their environment.
, Which statement about the properties of life is false? - Correct Answers -Organisms
have an unchanging, constant internal environment.
The teeth of grain-eating animals (such as horses) are usually broad and ridged. This
makes the teeth suitable for grinding and chewing. Meat-eating animals (such as lions)
have pointed teeth that are good for puncturing and ripping flesh. This illustrates -
Correct Answers -a result of natural selection, which connects form and function.
There are a number of properties that all organisms share. In humans, exposure to
ultraviolet light can result in a darkening of the skin. What kind of property is this? -
Correct Answers -response to the environment
In an ecosystem, energy - Correct Answers -typically flows from producers to a series of
consumers.
Which sequence lists organisms in the order of producer, consumer, and decomposer?
- Correct Answers -algae, bird, earthworm
When the human virus HIV first appeared, the mortality rate of infected individuals was
close to 100%. However, recent information shows some individuals are unaffected by
exposure to the virus. Why is this not surprising? - Correct Answers -Humans are
genetically diverse, and some are immune to the virus
The role of a control in an experiment is to - Correct Answers -provide a basis of
comparison to the experimental group.
To be of value to science, hypotheses must be __________. - Correct Answers -
testable
What is the benefit of the red panda's enlarged radial sesamoid? - Correct Answers -
The enlarged radial sesamoid acts as a "false thumb," enabling the red panda to grasp
objects by pressing one or more of its parallel digits to this "thumb."
The chemical energy used by most organisms for metabolism and growth ultimately
comes from __________. - Correct Answers -the sun
A hypothesis must be testable and *BLANK* --there must be some observation or
experiment that could show that it is not true. - Correct Answers -falsifiable
A(n) *BLANK* involves both an experimental group and a control group, which are alike
except for the one variable that the experiment is designed to test. - Correct Answers -
controlled experiment
A(n) *BLANK* is broader in scope than a hypothesis, is supported by a large body of
evidence, and generates many new hypotheses. - Correct Answers -theory
