What are the two types of reproduction?
What is: sexual and asexual

How many centimeters are in a meter?
What is: 100 cm
What is the definition of biology?
What is: the study of living things
What is the proper format of a hypothesis?
What is: If [IV] , then [DV].
What is the universal genetic code that all of life shares?
What is: DNA
The biggest level of organization, including all living and nonliving things on the planet, is called what?
What is: the biosphere
Name 3 abiotic and 3 biotic things.
What is: abiotic - sun, water, soil, rocks, temperature, fossils, biotic - animals, plants, bacteria, fungi
What is an observation?

What is: stimulus - an event, response - a reaction
Cells working together make up what?
What is: a tissue
Give an example of a good hypothesis.
What is: must include if, then, and IV and DV.
Give an example of an observation and an example of an inference. (You must get both correct for these points)
What is:
Observation: information gathered using the 5 senses
Inference: a conclusion based on evidence and observations
Why is it good to run an experiment multiple times or to have multiple trials?
What is: so the data is more reliable. This gets rid of outliers or "flukes"

What is the difference between the independent variable and the dependent variable?
What is: the IV is what is manipulated, the DV is the data that is collected or measured.
List the steps of the scientific method.
What is:
1. Make observations and come up with a question
2. Gather information
3. Make a hypothesis
4. Test the hypothesis
5. Analyze the data
6. Draw conclusions
Describe a mechanism of homeostasis.
What is: sweating to cool down, shivering to warm up, fevers to kill bacteria
What level makes up all living and nonliving things in a specific area?
What is: an ecosystem
In the following experiment, determine the IV, DV, and control. (You must get all three correct for these points):
Three seeds are planted. One is watered with normal tap water, one is watered with ice water, and one is watered with hot water. After 2 weeks, they are measured to see which one grew the most.
What is: IV - water, DV - growth, control - normal tap water
