Maya designed an experiment to answer the following question:
How does the amount of water given to a lima
bean seed affect how tall it grows?
In this experiment, what is the independent variable?
the amount of water
the kind of plant
how tall the plants grow
the amount of sunlight it gets
The type of variable that responds to the experiment and is what you measure or count to determine if your hypothesis is true.
Independent variable
Dependent variable
Controlled variable (constant)

Which statement most accurately compares the difference between scientific theories and scientific laws?
Scientific laws are based on evidence while scientific theories are not
Scientific theories involve only biology, while scientific laws involve all types of science.
Scientific theories involve mathematical equations, while scientific laws are based on observations.
Scientific laws predict or state what will happen in a natural event, while scientific theories explain why those events happen.

Asexual
Sexual
Division
Addition
What is an autotroph?
an organism that can make their own food.
an organism that cannot make their own food
an organism whose cells do not contain nuclei.
an organism whose cells contain nuclei.
Maintaining a stable internal environment is called
homeostasis
equilibrium
balance
evenness
The genetic material of an offspring of sexually reproducing organisms is best described as
identical to that of the other offspring
a copy of the genetic material of the mother
a copy of the genetic material of the father
genes from both parents, in unique combinations
Reproduction that involves cells from two different parents fusing to produce the first cell of a new organism.
Asexual
Sexual
Budding
Division
Which kind of organism is smaller?

What word describes any trait that helps an organism survive and/or reproduce in its environment?
natural selection
mutation
camouflage
adaptation
Why are advantageous (beneficial) traits more likely to be passed onto offspring?
Because individuals with those traits are more likely to survive and reproduce.
Because those traits come from dominant alleles.
Because those traits come from recessive alleles.
Because the organism knew it needed that trait, survives, and passes it on.
Dogs breeds are the result of what process?
Why is the mouse population changing over time?
(Click on the picture to enlarge it.)

frog
mouse
fish
Which type of biomolecule would a long-distance runner most likely choose to eat two hours before a race?
A protein, because it builds muscle mass.
A lipid because it provides long term energy storage.
A carbohydrate because it releases energy quickly.
A protein, because it transports oxygen into the blood stream.
