|
What is biology?
|
The study of all living things
|
|
|
What are the 6 groups/kingdoms of organisms?
|
(1) Archaea (2) Bacteria (3) Protista (4) Fungi (5) Plantae (6)
|
|
|
Explain the Archaea kingdom.
|
Prokaryotes(simple cells that don't have nuclei); methanogen(manufactures methane as a result of its metallic activity)
|
|
|
Explain the Bacteria kingdom.
|
2nd of two prokaryotic kingdoms; purple sulfer bacteria(can convert l
|
|
|
Explain the Protista kingdom.
|
Most unicellular eukaryotes(cells do contain a nucleus); multicellular
|
|
|
Explain the Fungi kingdom.
|
Nonphotosynthetic organisms; mostly multicellular; digest their food externally; mushrooms
|
|
|
Explain the Plantae kingdom.
|
Photosynthetic multicellular organisms; terrestrial (grows on land); flowering plant
|
|
|
Explain the Animalia kingdom
|
Nonphotosynthetic organisms; digest food internally
|
|
|
All living things share what 5 basic properties?
|
(1)Cellular organization (2)Metabolism (3)Homeostasis (4)Growth and reproduction (5)Heredity
|
|
|
Describe cellular organization.
|
All living things are composed of 1 or < cells; some simple & some complex; all grow and reproduce; mainly single-celled; body contains 10-100 trillion cells(varies on how big you are)
|
|
|
What is a cell?
|
A tiny compartment with a covering called a membrane.
|
|
|
Describe metabolism.
|
ALL living things use energy; energy required: moving, thinking, growing, everything you do; photosynthesis; we eat plants and plant-eating animals; ex: fish eat algae; use special energy carrying molecules:
|
|
|
What is photosynthesis?
|
Captures sunlight for plants and algae for energy
|
|
|
Describe homeostasis?
|
Living things maintain stable internal conditions; no matter how hot or cold the weather is, your body will maintain an internal temp. of 98.6 degree F
|
|
|
Describe growth and reproduction.
|
All living things grow and reproduce; bacteria grow and split into 2 every 15 minutes; can grow by increasing their # of cells[pine]
|
|
|
Describe heredity.
|
All organisms have a genetic system; DNA(deoxyribonucleic acid)[genetic code, replicates and duplicate for your entire life, contains genes(set of instructions), causes heredity]
|
|
|
Define heredity.
|
Transmission of characteristics from parent to offspring.
|
|
|
List the hierarchy of increasing complexity.
|
(1) Atoms (2) Molecules (3) Macromolecules (4) Organelles (5) Cells (6) Tissues (7) Organs (8) Organ systems (9) Organism (10) Population (11) Species (12) Community (13) Ecosystem
|
|
|
Describe the emergent properties.
|
b
|
|
|
List the stages of the scientific method.
|
(1) Observation (2) Hypothesis (3) Predictions (4) Testing (5) Controls (6) Conclusion
|
|
|
Describe the first step of the scientific method (Observation)
|
Observing what is going on
|
|
|
Describe the second step of the scientific method (Hypothesis)
|
A guess of what will happen that may be true.
|
|
|
Describe the third step of the scientific method (Predictions)
|
What you expect to happen if the prediction is true.
|
|
|
Describe the fourth step of the scientific method (Testing)
|
Experiment(the test of the hypothesis.
|
|
|
Describe the fifth step of the scientific method (Controls)
