Biology Chapter 1 Test Study Set
Tissue
A group of cells that performs a specific task.
Population
A group of individuals of the same species.
Statistics
A group of numbers that estimates the reliability of data
Hierarchy
A live visualization of layers of life
Way to remember the organization of living things...
A mole came to our octopus' ocean pretty cheery.
Experiment
A repeatable test of the natural world
Analytical study
A type of study that looks for patterns and data to find out what happens
Falsifiable
Able to be rejected
Controlled experiment
An experiment that compares a control group to a treatment group
Descriptive study
An observed study that tells information about nature's findings
Quantative
Analytical data
Organization of living things
Atoms, molecules, cells, tissues, organs, organ systems, organism, population, community (Important: Tissue, Organ, Organ System)
No, the Hypothesis cannot be proven 100% right.
Can the hypothesis be proven 100% right?
What is scientific knowledge based on?
Current knowledge
Qualitative
Descriptive data
Students
Example of DV
Sugar
Example of IV

Example of a Hypothesis Title
Group w/o sugar
Example of control group
An organ doing its job is (theory, hypothesis, fact, or experiment)?
Fact
Robert Koch
German physician and scientist who proved in 1890 the germ theory of disease, which is the basis of treating & maintaining hygiene.
Theory
Hypothesis confirmed by researchers with substantial data
What can be developed into a scientific theory overtime?
Hypothesis supported by repeatable experimental evidence holding true.
A hypothesis that has been tested and worked.
In science world, what does theory mean?
Data
Information collected during an experiment
Hypothesis
Informed and logical explanation of the natural world
Observation
Knowledge gained using science
Science
Knowledge of the natural world backed by evidence
What does the scientific method help do?
Make informed decisions.
How many DV's can experimental design have?
Multiple
How many IV's can experimental design have?
One
Variable
Part of something that can change
Peer-Reviewed Publication
Publishing of research validated by experts
Option #1: Does it work? Option #2: Is it falsifiable? Restart?
Questions to ask yourself about your hypothesis include...
Fact
Repeatable observation of the natural world
#1: Include current observations to a question #2: Must be testable
Requirements for hypothesis?
What does science include?
Science includes trying to solve a problem systematically and evaluating the evidence.
Why do scientists communicate their results?
Scientists communicate their results to enhance the quality and accuracy of their work by input, further review, and repetition by other scientists
Cell
The basic unit of life
Treatment group
The part of the experiment that has the change, or IV
Independent Variable (IV)
The thing that changes in an experiment
Dependent Variable (DV)
The thing that is being measured in the experiment
How do scientists avoid their bias?
To avoid bias, scientists share their findings through peer-reviewed publications.
If someone shows signs of illness, what are the facts?
To find out the facts or to diagnose their illness, they need to go to a medical professional and get tested.
Group with sugar
Treatment group
Science can not address God or other supernatural beings. Science can also not tell which opinions are right.
What can science not address?
Write their experiment down step by step.
What do scientists have to do with their experiment to claim it's theirs?
White Nose Syndrome
What does WNS stand for when talking about bats?
Unproven explaination
What has theory been used to describe?
Experimentation
What is the primary means to verify or refute the predictions generated to test a hypothesis?
When are scientists proposing a scientific hypothesis?
When scientists generate a single informed, logical, and plausible explanation for a question and observations of the natural world, they are proposing a scientific hypothesis
