In plants, simple sugars are least likely to be

linked together to form proteins

Which statement best describes a controlled experiment?

It tests the effect of a single independent variable.

Which statement describes starches, fats, proteins, and DNA?

They are complex molecules made from smaller molecules.

Which statement concerning simple sugars and amino acids is correct?

They are both needed for the synthesis of larger molecules.

A student checks his pulse before & after exercising. Purpose of checking his pulse before =

serves as a control for the experiment

1
One way to improve the validity of these results would be to
conclude light is necessary for lettuce seed germination
revise the hypothesis
repeat the experiment
conclude darkness is necessary for lettuce seed germination
2
Which group contains only molecules that are each assembled from smaller organic compounds?
proteins, DNA, fats, starch
proteins, starch, carbon dioxide, water
proteins, carbon dioxide, DNA, starch
proteins, water, DNA, fats
3
Explain the relationship between independent and dependent variables within a hypothesis.
IV = Cause, DV = Effect
IV = Effect, DV = Cause
IV = Manipulated, DV = Responding
IV = Responding, DV = Manipulated
4
Which two terms are considered to be opposite processes?
cloning and mitosis
photosynthesis and autotrophic nutrition
dynamic equilibrium and homeostasis
digestion and synthesis
5
In plants, simple sugars are least likely to be
broken down into carbon dioxide and water
stored in the form of starch molecules
linked together to form proteins
used as a source of energy
6
What substance could be represented by the letter X in the diagram below?
carbon dioxide
ozone
water
carbohydrates
7
An investigation is carried out to find the effect of anxiety on test scores. The DV is
test scores
control
anxiety
number of participants
8
Which statement best describes a controlled experiment?
It eliminates the need for dependent variables.
Shows the effect of a DV on an IV.
It avoids the use of variables.
It tests the effect of a single independent variable.
9
What should be included before the experiment can be started?
safety precautions to be used
a set of data
an inference based on results
a conclusion based on data
10
Starch stored in the cells of a potato is made of molecules that entered these cells as
simple sugars
amino acids
enzymes
minerals
11
Which statement describes starches, fats, proteins, and DNA?
They are used to assemble larger inorganic materials.
They are simple molecules used as energy sources.
They are complex molecules made from smaller molecules.
They are used to store genetic information.
12
Which statement concerning simple sugars and amino acids is correct?
They are both needed for the synthesis of larger molecules.
They are both building blocks of starch.
They are both wastes resulting from protein synthesis.
They are both stored as fat molecules in the liver.
13
A student checks his pulse before & after exercising. Purpose of checking his pulse before =
is needed to justify the sample size
is needed to formulate a hypothesis
serves as the conclusion for the experiment
serves as a control for the experiment
14
Give an example of a hypothesis in the correct format.
If I eat too much candy, then I will act like a fool.
You smell funny.
What is this "format" this crazy chick is talking about?
Why is the sky blue?
15
A biologist successfully bred a tiger w/a lion. Other biologists will accept this as fact if
research shows that other animals can be crossbred
the offspring are given a scientific name
other researchers can replicate the experiment
the biologist included a control in the experiment
16
The dependent variable in this investigation is the
amount of protein digested
time of digestion
amount of stomach fluid
size of the test tube
