viewing through a microscope

everything upside down and mirrored, so moving up moves down in the microscope, moving left moves right in the microscope.



prepared slides vs wet mount slides

(Diameter of a)(Magnitude A)= (Dia of b)(mag b)
diameters of the 4 powers under a light microscoper
4mm, 2mm, .4mm, .2 mm
as magnitude increases..
diameter of field of view decreases, working distance, depth of field, light intensity all decrease
Daphnia vs Simocephalus

both are clear and have clear body with the appendages, but daphnia have eggs inside them that are visible. daphnia has a pointed tail while simocephalus is not as long

bar graphs for data that represent separate or discontinuous groups or non-numerical categories.

structure of research papers (primary sources)
title, abstract, intro, methods and materials, results, discussion, references.
genotype vs phenotype

genotype is the genetic make, set of allels,


phenotype is the physical makeup, determined by genes and environment

gene
heritable unit that may influence a trait

alleles and locus

alleles are alternative dna sequences at same physical gene locus


locus is site on chromosome where gene located.

darwin
didn't know genes exists. publish origin of species. theory of natural selection as driving force of evolution. descent with modification
natural selection

process in which fittest organisms survive, find mates and reproduce. which results in their specific phenotypes being selcted for.


fitness is defined as ability of organism to survive and find a mate and produce offspring.

macroevolution vs microevolution

macro is evolution above the species level, micro is the species adapting


the main difference. speciation (allopatric and sympatric)

hardy weingberg principle

p2 + 2pq+ q2=1


p+q=1



5 conditions of hardyweingberg equilibrium

no mutations


no gene flow


no natural selection


random mating


large population

gene flow

migration of individuals to share traits, leave traits, etc



genetic drift
by chance, the bottleneck effect, founder effect
PTC
phenylthiocarbamide. chemical with bitter taste. tasters dominant. example of incomplete dominant because heterozygotes do not have full expression of either allele
types of selctio
stabilizing, disruptive, directional

sickle cell disease
autosomal recessive allele that causes sickle cells. people have this thing called heterozygote advantage that gives them protection from malaria.
allopatric vs sympatric
allopatric is separated by geographic barrier
molecular clock hypothesis

changes of genetic material of isolated populations are due to mutations that occur at constant rates. scientist are able to determine point when two specis diverged


mutations spontaneously at constant rates

darwins finches
when populations diverge, genetically different, may loose ability to interbreede so they would say speciation occured, when these were isolated on different islands, diff beak size.
behavior
response of organism to stimulus that can be external or internal or both such as mating behavior
homeostasis
organisms tendency to keep internal conditions constant
learned behavior vs innate

learned is from experiences such as imprinting, habituation, conditioning


innate is inherited such as reflecxed, fixed action patterns, instincts

proximate vs ultimate cause

proximate is immediate cause for behavior


ultimate is adaptive value

taxis verses kinese

orientation behavior


taxis is directional behavior in response to stimule, towards or away


kinesis is non directional movement


(positve or negative would be increase or decrease in movement.)

agonistic behavior
conflict behavior, threatening, agression, submission
reproductive behavior
series of activites for finding a mate, courting, and mating, species specific

black planaria
freshwater worms, exhibited negative phototaxis
chemotaxis in paramecium
experienced acetic acid as a chemorepellant
betta splendens agonistic display

they flare out their fins and gill covers to appear more impressive for courtship or intimidation. have high intesity of their ventral fins and pectoral fins in front of mirror.



fins on betta fish
dorsal up top, pectoral is on the side, pelvic is front side bottomish, anal is bottom, caudal is tail fin
bacteria
unicellular proks that lack nuclus and membrane bound organelles, have nucleoid

both are vasulcar plants with true stems and roots and leaves and are seed plants.


both have dominatnt sporophyte and reduced gametophyte. gamteophyte dependent on surrounding sporophyte for nutrition


gymnosperms are seed bearing plants that dont prduce flowers or fruits. naked seeds


angiosperms have seeds enclosed in an ovary.


flowering plants


gymno are like cones and pollen cones


angio spers have flowers with the gametophytes on the anthers and ovules

charophytes
the outgroup, closest related protists to land plants

dicot has two cotyledons, veinsa re netlike, ring vascular tissue, taproot, three opening on pollengrain, flowers multiples of four or five

difference in angiosperm and gymnosperm life cycle

gymno by wind while angioos by pollination


angios have 3n stage with endosperm.


sperm of angios go into the ovule to fertilize and release sperm again

chondrichthyes

sharks belong to this class along with rays, ratfishes


they have cartilaginous skeleton, jawed vertabrates with paird fins and placoid dermal scales, thick skin, ectothermic.


have internal fertlization. are ovoviviparous so they fertilize internally, but no placental connection because of egg, they hatch inside mothers and nourished by egg yolk.


have claspers on pelvic fins where sperm enters the females cloaca. have spiracles which are gill slits and spines on dorsal fins and they have gills.


oil filled liver, trwo chambered heart, spiral valve as part of small intestine

includes frogs, toads, salamanders, newts


go through metamorphosis from tadopole to adule. external fertillization, fat bodies.


tadpoles have tail for locomoton


tadpoles grow front legs to become froglets then lose tail to become adult frog once build lungs and back legs.


ectothermic so temp depends on environment.

ecology
the study of interatctions between living organisms and envrionment

abiotic factors vs biotics

abiotic is non living such as light, temp, air, water wind humidity, ph,


biotic is living facots such as other organisms that share habitat

trophic levels

produces that capture light and energy and transfer to organic moleecules


consumer taht consumer producers.


herbivores, carnivores and omnivores


apex consumers are the top of food chain


decomposers (fungi, bacteria, earthworms, dung beetle, insects, etc.) that consumer organic waste and dead organisms (saprobes and detrivores) recycle the nutrients for the producers

foodweb
relationships of predators and more trophci levels as a web/network of arrows to what they eat. so can eat form more than one level.
ecological pyramids. pyramid of energy
producers capture 1% of energy of sun and then only 10% of every level gets passed on so the primary consumer will only get .1% of energy and so on.

pyramid of biomass

total mass of organisms at each trophic level in pyramid


similar to that of light where they get thinner but can also be inverted in marine ecosystmes
