Learning about Human Bio-Exam 1 Flashcards
What living things do
- Capture and use energy and raw materials
- Send and respond to the environment
- Reproduce and grow (Stages)
How do living things sense and respond to the environment?
Shivering, sweating, putting on clothes, etc.
Do living things consist of one or more cells?
Yes, single or multicellular
Do living things maintain homeostasis?
Yes, they maintain a normal range
What are the six kingdoms?
-Eubacteria
-Archaebacteria
-Protistans
>Fungi
>Plants
>Animals
What two groups make up the animal kingdom?
Mammals and vertebrates
Are all mammals the same?
No
Is there any one characteristic that seperates mammals from vertebrates? If so, what is it?
No
Lifes Organization (CMPCEB)
- Cell
- Multicellular Organism
- Population: Human population
- Community: ex. Kern County
- Ecosystem: Pop. + Environment
- Biosphere: Planet Earth
Everything that is alive is a…
cell
Human Population
2 or more of the same organisms
Community
group of different organisms
Ecosystem
2 different community groups
Biosphere
2 different ecosystems
Scientific Method (5)
- Observe phenomenon
- Develop Hypothesis
- Make Predictions
- Test accuracy of predictions (experiment)
- Analyze and report results
Two groups in experiment
experimental group
control group- unmanipulated group/ “independent variable”
What kind of reasoning is used in experimentation?
Deductive reasoning
Two types of scientific reasoning
Inductive- less commonly used
Deductive
Inductive Reasoning is…
Specific—> General
-uses facts
Deductive Reasoning is…
General —> Specific
- it is only as good as the information that goes in
The role of experiments is to..
design something
- can never prove a hypothesis 100% wrong
What is a Control Group?
A standard for comparison
-Identical to experimental group except for variable being studied
Sampling Error
non-representative sample skews results
We can minimize sampling error by
using large samples
