INTRODUCTION
What is the definition of Biology?
Study of living things or making questions about how living things interact in the environment.
Basic and fundamental unit of life
The Cell
Groups of similar cells together carrying out similar or related functions.
Tissue
Having to give up something to achieve or gain something else.
Trade-off
The systematic process that must be followed to obtain the truth in science.
Scientific Method
Why do scientists do experiments?
Define homeostasis.
Keeping internal conditions stable or in balance.
The word for one living thing
Organism
What are 3 safety procedures when working with heated glass.
Wear safety goggles.
Use tongs to move glassware
Close toed shoes
Let others know it is hot
Wait until it is cooled to wash it
The process of recording your visual descriptions and numbers in your data table
Making qualitative and quantitative observations
What does CER stand for and when do we use it?
Claim, Evidence, Response. We use it when drawing conclusions and sharing out data
It is the ability of living things to recondition themselves to environmental factors.
Adaptation.
Organisms of the same species living within a specific area
Population
Definition of testable hypothesis
You need to be able to set up an experiment that can prove if they hypothesis is correct or not.
What is the difference between the independent variable and the dependent variable?
Why do scientists use models? (2 parts)
- Explain information that is very small, very large, or complex.
- Used to make predictions
What is the definition of both growth and development.
Growth results in an increase in mass.
Development results in different abilities.
Relationship of all living and nonliving things that interact in the environment where they live.
Biosphere
What is the definition of Theory?
Explanation of a natural phenomenon supported by observations and experiments over time.
Since brine shrimp hatched best at 3% salt solution, that means all species of shrimp will survive best at 3% salt solution.
State that the data refuted the hypothesis. Support the statement with evidence.
Enlist the 8 Characteristics of living things.
Made of One or More Cells, Has heredity (DNA/RNA), Grows and Develops, Reproduces, Respond to Stimuli, Requires Energy, Maintains Homeostasis, Adaptations evolve over time.
Order the following from smallest to biggest:
Atoms // Community // Organs Systems // Ecosystem // Biosphere // Cell
Correct Order: Atoms, Cell, Organs Systems, Community, Ecosystem and Biosphere
How do you know a claim is valid? (Name 2 reasons)
Supported by the data
A large number of data
Observations of unbiased investigations
Carefully controlled experimentations
Reproducible
Peer review is important part of the process. When reviewed by peers, what are 3 things they are checking for?
Originality, Competence to the Scientific Method, Accuracy, Reproducibility, bias, errors
