BIOL 1104 TEST 1
traits - Correct Answers -identifiers, qualities, measurements, parts that help us put
things into categories: discrete vs continuous
biology - Correct Answers -study of life & how it's organized
distributions - Correct Answers -way of summarizing trait data to visualize probabilities
& test hypotheses
populations - Correct Answers -defined by location, culture, trait value, genetics
(heritable diversity)
-representative samples let us summarize diversity in statistics to compare
properties of life - Correct Answers -order (single-celled vs multi), positive response
toward stimuli (movement towards), reproduction, adaptation, growth & dev (genes),
regulation (internal functions), homeostasis, energy processing (ie photosynthesis)
levels of organization - Correct Answers -atom, molecule (2+ atoms), macromolecules
(DNA), organelles, cell (prokaryote vs eukaryote membrane bound), tissue, organ,
organ system, organism, species, population, community, ecosystem, biosphere (+ land
& water)
reasoning - Correct Answers -inductive (uses related observations to arrive at general
conclusion) vs deductive (uses general law to forecast specific results)
basic vs applied science - Correct Answers -basic seeks to expand knowledge &
applied uses science technology to solve those real world problems & gain that
knowlesge
3 main life cycles - Correct Answers -diploid-dominant, haploid-dominant, alternation of
generations
article: opioid crisis - Correct Answers --leading cause of death for americans younger
than 50
-purdue pharma ad for oxycontin increased use dramatically but gave false info so was
sued
, -2001: joint commission made pain monitoring the "5th vital sign" which also increased
use
mendel: model system - Correct Answers -system that is used to study a specific
biological concept or organism to gain understanding to be applied to other systems
rather than try to learn everything about every single organism
continuous variation - Correct Answers -variation measured on a continuum rather than
in discrete categories i.e. height ; mendel thought we had blended inheritance or
intermediate traits
discontinuous variation - Correct Answers -each individual shows 1 of 2 traits i.e. violet
flowers or white flowers
allele - Correct Answers -gene variants that arise by mutation but exist on homologous
chromosomes
-homozygous organisms have 2 identical alleles (YY)
-heterozygous organisms have 2 different alleles on same chromosome (Yy) "carriers"
law of dominance - Correct Answers -one trait will conceal the presence of another trait
for the same characteristic
law of segregation - Correct Answers -paired genes must separate equally into gametes
such that offspring have an equal likelihood of inheriting either factor
law of independent assortment - Correct Answers -genes do not influence each other
with regard to sorting of alleles into gametes; every possible combination of alleles is
equally likely to occur - random
incomplete dominance - Correct Answers -dominant does not 100% mask recessive, so
you see a blending of traits; phenotype 1:2:1
wild type - Correct Answers -the gene expression you would find in a natural
environment; most common
epistasis - Correct Answers -one gene suppresses expression of another
structure of DNA - Correct Answers --contains genetic material passed from parent to
offspring
-nucleotides: deoxyribose + phosphate group + nitrogenous base (A, G, C, T/U for
RNA)
-double stranded helix
collectors vs scatterers - Correct Answers -collectors: autotrophs, they [ ] carbon,
energy & minerals in food
scatterers: heterotrophs, they digest food & release its contents to the env
