Test #1 Flashcards
What is science?
The use of evidence to construct testable explanations and predictions of natural phenomena and the knowledge generated through this process
What are the limits of science?
cannot make moral or aesthetic judgments
What is a hypothesis
a proposed testable explanation for a narrow set of phenomena
What is not a hypothesis
predictions or educated guesses
Explain the difference between hypotheses and theories
Theories are more broad and supported with many lines of evidence
Qualitative
the quality of the data
Quantitative
the amount of data
Biology roots, prefix, and suffix
bio = life, logy = study (Greek) study of life
Hydrophilla roots, prefix, and suffix
hydr = water philic = loving (Greek) water loving
Hydrophobia roots, prefix, and suffix
hydr = water, phobia = fearful (Greek) water fearful
Arthopod roots, prefix, and suffix
arth = conjoined, pod = one (Greek) joint limbs
Prokaryote roots, prefix, and suffix
pro = before, karyon = nut/kernel (Greek) organism without a nucleus and membrane bound organelles
Eukaryote roots, prefix, and suffix
eu = well, karyon = nut/kernel (Greek) organism with a nucleus and membrane bound organelles
Compare and contrast random errors and systematic errors
Random errors and Systematic errors both cause harm to the experiment results, but Random errors are caused by random occurrences, and systematic errors are caused by issues in measuring instruments.
Design bias
Introduced when the researcher fails to take into account the inherent biases liable in most types of experiments
Selection bias
occurs when the process of sampling actually introduces an inherent bias into the study
Procedural bias
an unfair amount of pressure is applied to the subjects being studied
Reporting bias
a scientist’s beliefs influence their conclusions
Measurement bias
Systematic errors that favors a certain measurement over another
What makes science trustworthy?
peer review
Orderly structure
organisms have a cell structure
Growth and development
organisms can grow and develop overtime
Reproduction
organisms can reproduce off springs
Metabolism
using energy to carry out the functions of its cells
Homostasis
maintain a steady internal environment regardless to external conditions
Response to environment
survive with external changes
Evolutionary adaption
adapt and evolve to external procedures
Taxonomy
the science of classifying organisms
Binomial Nomenclature
the 2 name system for classifying organisms
How has the classification of life changes over time?
Because scientists new discoveries add to our classification system and how each group is divided
What is the main limitation of the Lineman classification system
only based on physical similarities, and not any genetic similarities
Correct order of the classification system from greatest to least
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
pathogen
any living organism that can cause infectious disease
prions
infectious particle made up of proteins that cause other proteins to fold incorrectly
viroids
infectious particle that causes harm to plants
viruses
infectious particle made up of a strand of dna in a protein coat
obligate aerobe
needs oxygen to live
obligate anarobe
cannot live with oxygen
Bacteria and Archaea arnt classified together because of?
their different living conditions
Bacillus
rod shaped bacteria (E-coli)
Spirillum
spiral shaped bacteria (Lyme disease)
Coccus
ball shaped bacteria (staphylococcus)
binary fission
reproduction process for prokaryotes that involves splitting into 2
Name the 6 modes of disease transportation
Airborne, Food/waterborne, vector, sexual, blood borne, and contact
What bacteria infected Addie and what happened?
Staphylococcus and it got into her bloodstream
Marcus Vitruvius Polio
proposed the vitruvian man theory
Carlos Linneus
first proposed the Linnean classification system
John snow
found that chorea is transmitted through water
