How does the growth among living and nonliving things differ?
Living organisms go through cell division, non-living things do not.
100
Define reproduction
The process by which an organism produces new organisms like itself.
200
Explain why the cell is called the basic unit of life.
Cells are the smallest unit that can perform life processes
200
Give an example of a domain.
Bacteria, Archaea, Eukarya

A statement that explains observations and can be tested is called...
A hypothesis
200
Homeostasis refers to the
Stable level of internal conditions
200
Give an example of how two organisms are interdependent
Animals produce carbon dioxide and water, which
is needed by plants.
Or other acceptable answer.

How are rocks different from living things? Give at least 3
Rocks don't have a metabolism, don't reproduce, don't grow or develop, don't have cells, don't respond to stimuli
300
A trait that improves an individual's ability to survive and reproduce is a(n)
adaptation

What are quantitative data? Give two examples of quantitative data.
Quantitative data are data that can be measured in
numbers.
Examples include the dimensions of an
object, the number of objects in a group, and the
duration of an event.

What is an advantage of a peer review of a scientific paper?
The validity of the research is checked by experts
in the field.
400
Contrast the reproduction of bacteria with that of frogs.
Frogs reproduce sexually. Bacteria reproduce asexually (split into two new identical cells)
400
What is natural selection?
The process by which organisms that have certain favorable traits are better able to survive and reproduce successfully
400
Define Independent variable and dependent variable
An independent variable is a factor that is changed by the experimenter.
A dependent variable is affected by the independent variable and measure by the experimenter.
400
What are the different functions of homeostasis and metabolism in living organisms?
Homeostasis allows an organism to maintain a constant temperature in order to survive, metabolism allows and organism to get energy from food.
400
Distinguish between diversity of life and unity of life
Diversity of life describes the variety of different kinds of living things.
Unity of life describes the features that living things have in common.
500
Summarize the hierarchy of organization found in complex multicellular organisms
Cells, tissues, organs, organ systems, organism
500
Why must an adaptation be inheritable if it is to cause a population to evolve?
If an adaptation is not inherited, future generations
of organisms will not have the favorable trait and
evolution cannot occur.
500
Summarize the parts of a controlled experiment
A controlled experiment contains a control group that provides a standard for comparison, experimental group that is identical to the control group except for one factor and the independent variable that the experimenter is testing for.

Crystals of salt grow and are highly organized. Why don’t biologists consider them to be alive?
Salt is unable to go through cell division and cannot reproduce
500
How are a hypothesis, a prediction, and an experiment related?
A prediction is a statement made in advance that
declares the results that will be obtained from
testing a hypothesis in an experiment, if the
hypothesis is true.
