Chapter 1 Study Flashcards
Rules for species names:
Always italicized
Genus name can be abbreviated after being spelled out once
Genus always capitalized, epithet lowercase
Who was Carolus Linnaeus
Invented Linnaean system (every species given two part name)
Invented Binomial nomenclature
Created Linnaean classification system
Who was Carl Woese
Invented idea of 3 domains after looking at rRNA
Defined archaea
Name 2 organ systems:
Reproductive system and digestive system
Chemosynthesis:
changes inorganic compounds into usable organic ones
Catabolism:
breaking materials down into smaller molecules
Types of autotrophs
Phototrophic autotraphs
lChemotrophic autotrophs
Positive feedback
Amplifies change
Blood clotting
Labor
Negative feedback
negates change
Body terperature
blood sugar
Insulin allows
cells to open and take in glucose
Zygote cells…
differentiate and specialize
What does DNA guide?
Growth
Development
Reproduction
Chromosone
DNA organized state
Bacteria are decomposers?
Yes
Arachea live…
very high temp, low salinity
What type of heterotroph are fungus?
Absorptive heterotroph
What type of heterotroph is animal
Ingestive heterotroph
Examples protists
Algae, amiba
Fungus example
Mushroom, truffle
A controlled experiment consists of…
control group and experimental group
List pitfalls of science
Sampling Error – more tests/ larger sample
Bias in interpreting results – quantitative
Doesn’t address supernatural, sometimes public not ready
test tube rack
holds many test tubes
test tube holder
tool used to grip test tube
Droppers also called
pipettes (some have bobes, other pumps)
Scalpel
Sharp instrument used for dissection
Objective lenses
optical elements closest to the specimen.
nosepiece
part of the microscope that holds the objective lenses (revolves)
body tube
tube look into with lens
Diaphragm
rotating disk under the stage to vary light project upwards
Example Hypo:
A change in temp will increase rate of reaction
Prediction ex:
If I increase the temp, the reaction will happen faster
Rerun
Recall Explain Results Uncertainties New things
Molecules of life example
lipids, DNA proteins
Are the brain and hear organs?
Yes
Tissue types:
muscle, epithelial, connective and nervous
DNA requirement
Use it as hereditary material
Are decomposers consumers?
Yes
Nutrients flows between…
producers and consumers
Can bacteria/arachea be producers/do photo.
Yes
Purpose of nucleus
Protect dna
What are most diverse group of organisms?1
Bacteria/arhchea collectively
Are some fungi decomposers?
Yes
Most plants have…
root, leaf, and stem
What are the traits that regard masking/using molecules?
Biochemical traits
Do protists include the most ancient mulitcelled elks?
Yes
Why isn’t BSC working?
Pops continue to interbreed as they idverge
don’t know if separate pops could interbreed
Is using a hypothesis to make a prediction deductive reasoning?
yes
Steps in scientific method
- Observe
- Form hypo
- Test hypo
a. make prediction
b. Test prediction with experiment
c. analyze data - Conclusion
- Report
Ways to combat Sampling Error?
Larger sample sizes Probability calculations (if 5% or less of being skewed, is SS)
Combat Bias?
Quanititative
Scientists not know which groupsp is which
Scientists check each other1
Rules of scientists (2)
work concerns only natural world
must be testable by others
What is most objective way to describe natural world?
Scientific theory
Examples of scientific theories
Atomic theory (all have atoms) Global warming (humans causing temp increase)
