Terms
undefined, object
copy deck
- theory
- explanation supported by evidence, can never be conclusively proved, is modified as new facts are discovered/new interpretations
- geographical isolation
- limits gene pool
- photosynthesis
- stores sunlight energy in glucose
- maternal twins
- 1 egg+ 1 sperm, can share a placenta, identical
- Cells are the basic units of life
- Cell theory part two
- Carson
- "Silent Spring"
- succession
- gradual change/replacement process in an ecosystem over time from one kind to another
- homologous structure
- same structure, made same way, may have same function
- heat
- Oparin's theory stage two
- Mendel
- Laws of inheritance, contemporary with Darwin
- Law of Dominance
- when the two alleles of a pair are different, one can be dominant and the other recessive, dominant will mask recessive
- mesozoic
- dinosaurs
- reproductive cline
- extremes can't breed even though intermediates can
- Linnaeous
- Latin names/classification
- divergent
- selection pressure pushes them apart
- Big Bang
- 15 Billion Years ago
- bottleneck effect
- environment only allows few to survive, leads to a small gene pool
- All life is made of cells
- Cell theory part one
- Virchow
- third part of cell theory
- Darwin
- Wrote Origin of the Species, natural selection, favors those suited to change (theory of...)
- Pasteur
- no spontaneous generation, contradicts theories of evolution (theory of...)
- analogous structure
- same function, not made the same
- no oxygen
- Oparin's theory stage four
- Lyell
- Wrote Principles of Geology, physical forces that shape the earth have always existed (theory of...)
- Hershey and Chase
- connected DNA to heredity
- natural selection
- survival of the fittest
- Galen
- dissector
- genetic drift
- isolation of a small population with limited gene pool (greater % of certain genes than other pops.)
- Law of Independent Assortment
- how each pair of chromosomes align and segregate, varies in each gamete formation
- Gould
- Theory of Punctuated Equilibrium based on lack of evidence for intermediate organisms, stable longterm population with rapid change
- universal receiver
- blood type AB
- natural selection
- "painted pot" model-male+female contribute equally and traits blend (incorrect)
- universal donor
- blood type O
- convergent
- come together
- diffusion
- molecules move from a high concentration to a low concentration
- Law of Segregation
- when gametes are produced, homologous chromosomes separate or segregate leaving them with one of each kind
- paleozoic
- fish
- Hooke
- cork cells, named "cells"
- Needham
- boiled broth with loose seals experiment
- Aristotle
- first biologist, proposed spontaneous generation
- fact
- measurable, observable, can be investigated experimentally
- fraternal twins
- 2 eggs, 2 sperm, separate placentas, non-identical
- Spallanzani
- boiled broth for long time experiment
- Earth Forms
- 4.6 Billion Years ago
- cenozoic
- mammals
- eons of time
- Oparin's theory stage three
- Schleiden and Schwann
- observed plant cells/animal cells, cell theory
- temporal isolation
- breed different times of year/active different times of day
- Redi
- meat maggot experiment
- founder effect
- 1 or a few mating pairs isolated and forced to interbreed and change quickly, eventually not able to breed with parent population
- energy
- Oparin's theory stage five
- natural selection
- change in the environment favors those suited
- New cells come from preexisting cells
- Cell theory part three
- organic soup
- Oparin's theory stage one
- Watson and Crick
- DNA double helix shape discovered
- Lamarck
- a body responds to the environment and changes to meet the needs (theory of...)
- sickle cell anemia
- this disease is an example of a heterozygote advantage
- Leeuwenhock
- described living cells/improved microscopes
