directional selection
Give this one a try later!
favors one extreme phenotype, usually when a population moves into a
new environment (classic example of Darwin's finches)
sucrose
Give this one a try later!
composed of one glucose molecule and one fructose molecule.
,explain identifying saturated vs. unsaturated fats
Give this one a try later!
saturated: only single bonds in hydrocarbon chain... unsaturated: one or
more double bonds
net primary productivity
Give this one a try later!
total productivity with losses from resp and other energy use by plants
subtracted
karyogamy
Give this one a try later!
fusion of male and female nuclei
density-dependent inhibition
Give this one a try later!
normal cells able to suppress growth when near other cells
,annelida
Give this one a try later!
earthworms; leachces
obligate anaerobes
Give this one a try later!
cannot survive in presence of oxy
neutral stimulus
Give this one a try later!
stim that will not by itself elicit a response
bilaterally symmetric
Give this one a try later!
organized along one vertical or horizontal axis and tend to be long or thin
, segregation
Give this one a try later!
2 alleles for given trait seperate during meiosis
cladistics
Give this one a try later!
grouping of species determined to be related because of distinguishing
novel feature
crossing-over
Give this one a try later!
the exchange of segments of DNA between homologous chromosomes
triple repeat extension
Give this one a try later!
number of repeats increases with each generation
