What is Biology?
The study of life
T/F
All living things are made of one or more cells.
True
A person should eat 2-4 times per day to stay healthy. What characteristic of life does this demonstrate?
Metabolism/energy
Where does the independent variable go on a bar graph?
X-Axis
What are extraneous variables?
Variables that may affect the outcome of an experiment that were not taken into account
What are some of the things biologists study?
Biologists may examine the features of living things and their habitats. Biological research in medical treatments and disease prevention. Endangered species.
T/F
Only some living things show an orderly structure
False, all show structure
A goat has hooves (feet) that easily grip mountain sides, allowing to climb very well. What characteristic of life does this demonstrate?
Adaptation and evolution
Where does the dependent variable go on a bar graph?
Y-Axis
Which group reflects natural/normal/regular conditions and acts as a comparison tool?
Control group
Are bacteria alive? Why/why not?
Yes, they show all 8 characteristics of life
In which organisms are cells the basic unit of structure and function
All living things
A horse has the same coat texture as its mother. What characteristic of life does this demonstrate?
DNA/Heredity
Who/what controls the independent variable?
The experimenter
A mountain changes shape and size over time, is home many organisms. Is the mountain alive? Why or why not?
No, does not show all characteristics of life.
What molecule controls heredity?
