Which of the following shows a bad procedure for testing white-tailed deer food preferences?

Observe four deer in different locations and times

Neither group reported a case of the flu. Which would have made the study more valid?

test a third group that does not receive the supplement

What would be a valid hypothesis for this experiment?

Removing potassium will affect plant growth

Which statement is the best procedure to learn if a vaccine in a certain bird species is good?

Vaccinate half the birds and expose all 100 to the disease

What is the purpose of the field without magnesium?

To compare the plants under normal conditions

Conclusions based on an experiment are most likely to be accepted when they are

consistent with experimental data and observations

Which data should be collected to support this hypothesis?

diameter of the cotton bolls in both fields

A biologist reported success in breeding a tiger with a lion. This will be accepted as fact if

other researchers can replicate the experiment

What other information should the student include in his experiment?

How fast the dogs ate their normal food

What would the independent variable in this experiment?

Temperature of the seeds during growth

What is the relationship between the age of the mother and occurrence of Down's Syndrome?

As the age increases, the occurrence of DS increases

A valid inference based on these data is that

most photosynthetic organisms live above a depth of 150 cm

To improve the reliability of these results, the student should

repeat the experiment using a larger number of seeds

Which of the following shows a bad procedure for testing white-tailed deer food preferences?
Observe four deer in different locations and times
Observe 200 deer in various settings, but none in captivity
Observe 300 deer in captivity, but none in nature
Observe 500 deer in 20 different locations and times
2
The component missing from this experiment is a
prediction
hypothesis
control group
research plan
3
Neither group reported a case of the flu. Which would have made the study more valid?
test on both groups for 5 weeks instead of 10 weeks
test only one group with 200 mg of the supplement
test a third group that does not receive the supplement
test a third group that receives 150 mg of the supplement
4
What would be a valid hypothesis for this experiment?
Removing potassium will affect plant growth
Adding essential minerals will affect plant growth
Adding potassium will affect plant growth
Plants can grow well in flasks
5
What is the name of the equipment shown in this experiment?
Flask
Test Tube
Beaker
Graduated Cylinder
6
Which statement is the best procedure to learn if a vaccine in a certain bird species is good?
Vaccinate half the birds, expose only those to the disease
Vaccinate 100 birds and expose half of them to the disease
Vaccinate 100 birds and expose all 100 to the disease
Vaccinate half the birds and expose all 100 to the disease
7
What is the volume of water represented in the graduated cylinder shown below?
15.0 mL
10.3 mL
14.0 mL
13.0 mL
8
What is the purpose of the field without magnesium?
To understand the effect of water on the plants
To experiment is several different locations
To test chemicals other than magnesium
To compare the plants under normal conditions
9
What information would be placed on the x-axis when graphing this information?
Level of Dissolved Oxygen
Amount of Algae
Water Temperature
Number of Fish
10
Conclusions based on an experiment are most likely to be accepted when they are
testing only one hypothesis
consistent with experimental data and observations
based on only one experimental design
from investigations having many experimental variables
11
What is the dependent variable in this experiment?
Rate of Reaction
0 - 0.05
Substrate Concentration
Amount of Enzyme
12
Which data should be collected to support this hypothesis?
color of the cotton bolls in both fields
diameter of the cotton bolls in both fields
height of the cotton plants in both fields
length of the growing season in both fields
13
A biologist reported success in breeding a tiger with a lion. This will be accepted as fact if
the biologist included a control in the experiment
the offspring are given a scientific name
research shows that other animals can be crossbred
other researchers can replicate the experiment
14
What other information should the student include in his experiment?
If the dogs were indoor dogs or outdoor dogs
Age of the dogs
How fast the dogs ate their normal food
Color of the dogs
15
Which laboratory equipment would be most best for measuring liquids?
Scoop
Graduated Cylinder
Beaker
Balance
16
What would the independent variable in this experiment?
Temperature of the seeds during growth
How far north or south each seed was planted
Height of the trees after time
Number of seeds per tree
17
What is the relationship between the age of the mother and occurrence of Down's Syndrome?
As the age increases, the occurrence of DS increases
Age of the mother has no relationship with DS
As the age increases, the occurrence of DS decreases
As the age increases, the occurrence of DS is constant
18
The dependent variable in this experiment is the
pulse rate of each group
age of participants in each group
amount of soda given to each group
type of soda given to each group
19
A valid inference based on these data is that
most photosynthetic organisms live above a depth of 150 cm
oxygen increases as photosynthetic organisms move deeper
photosynthetic organisms respond to changing light levels
organisms move up to increase carbon dioxide production
20
To improve the reliability of these results, the student should
revise the hypothesis
conclude that light is necessary for seed germination
conclude that darkness is necessary for seed germination
repeat the experiment using a larger number of seeds
