Watching salt crystals form as ocean water evaporates, a student says, "Look−−more and more
crystals are appearing. The ocean water is alive!" Which statement is an accurate evaluation of
the student's remark?
The student is incorrect because all of the crystals reproduce the same kind of crystals with no
variation to provide adaptation, so the ocean water is not alive.
If you eat a hamburger, you are mainly eating ground-up beef muscle. What levels of
organization are represented in this ground-up muscle?
organelle, cell, and tissue
Is this statement true or false? Energy cycles from organisms through the atmosphere and back to
the organisms.
False
Which sequence is not a correct pathway of energy through an ecosystem?
-insects > birds > bacteria
-plants > insects > birds
-plants > birds > bacteria
-bacteria > plants > birds
Submit
bacteria > plants > birds
To be scientifically valid, a hypothesis must be
testable and falsifiable.
A scientist performs a controlled experiment. This means that
two versions of the experiment are conducted, one differing from the other by only a single
variable.
,You notice that over the past month, many students on campus have started wearing a new style
of school sweatshirt. You think to yourself that perhaps the bookstore has recently started selling
this new sweatshirt style. This is an example of a(n)
-type of observation

-experimental question
hypothesis
A theory is a(n)
Explanation of an idea that is broad in scope and supported by a large body of evidence.
When a scientist examined museum specimens of a particular moth species, she noticed that the
variation in color was distributed as shown in the first graph. She was surprised because her data
from current collections indicated the distribution of colors shown in the second graph. Which
hypothesis about the cause of this shift in the range of genetic variation is the most likely to be
supported by examination of the distribution of colors in a collection assembled at a time
between that of the collection of the museum specimens and her current specimens?
Darker moths were more likely to survive and have offspring over time.
Which statement provides the best evidence that there is a common genetic code that
demonstrates the unity of life?
-Many insects can pollinate only a particular species of plant due to many generations of
evolutionary adaptation.
-Bees, birds, and bats all have wings and fly.
-Through genetic engineering, a gene from a firefly can be inserted into a bacterium to make it
glow.
Submit
Through genetic engineering, a gene from a firefly can be inserted into a bacterium to make it
glow.
Submit
Which statement about ecosystems is false?
-In the process of energy conversions within an ecosystem, some energy is converted to heat.
-Chemical nutrients cycle within an ecosystem.
-Plants and other photosynthetic organisms are producers in ecosystems.
-Bacteria and fungi recycle energy within an ecosystem.
Submit
Bacteria and fungi recycle energy within an ecosystem.

, The box numbered 2 represents what process?
cycling of matter
Submit
A hypothesis is
