Bio 114 Test 1 Questions and Correct
Answers
Science ✅the process of identifying patterns and asking questions to understand those
patterns
Theories ✅consist of patterns and processes
pattern- observation of repetition
process- the way the pattern happens
- proximate: short term
- ultimate: long term
Cell Theory ✅all organisms are made of cells
Means 2 things:
- studying cell biology = studying life
- life is continuous: cells came from gamete
Evolutionary Theory ✅all life is the product of evolution
evolution is the heritable/genetic change in population over time
Organisms
What is an organismal scientist concerned with? ✅individuals
how organism survives as a result of behaviors and physiology, how it behaves
Population
What is a population biologist concerned with? ✅group of individuals in same species
evolution affects populations
Concerned with
- population growth, evolutionary processes
Communities
Community biologist concerned with? ✅- collections of populations of different species.
boundaries made by natural structure or us
- care about diversity of species and relationships between species
Biome ✅collection of similar ecosystems
Ex.) desert, tropical rainforest
Biosphere ✅all the ecosystems put together
sunlight goes in heat goes out
- concerned with climate change
Emergent Property ✅collection of the units at one level
defined as/helps to define the next level in the hierarchy
- give the next level in the hierarchy an evolutionary advantage
Ex.) evolution = emergent property of populations
reproduction = emergent property at organismal level
Aristotle's Great Chain of Being ✅rank of all beings with humans at the top
Lamarck ✅1st to say that species changed over time
but wrong about the giraffe neck theory
he thought species changed through acquired characteristics from environments than
passed it on. (he was wrong)
Darwin and his theory ✅evolution by natural selection
1) All species have a common ancestor
2) All species show changes in characteristics over time
3) All species show characteristic changes in different environments
4 Things Required for Natural Selection (define it too) ✅- process by which evolution
can occur
Trait Variation
Heritability
Differential Survival
Differential Reproduction
Fitness ✅# of offspring relative to other members of your population
Adaptation ✅heritable trait that increases relative fitness of individual
process by which individuals acquire traits
adaptation = fitness enhancing vs. natural selection and selective pressures
Macroevolution ✅change of one taxonomic group into another
Ex.) fish to reptile
