BIO 100 FINAL EXAM REVIEW
QUESTIONS & ANSWERS 100%
CORRECT
Nerve impulse - ANSWERCaused by a change in difference in positive and negative
ions on the outer and inner surfaces of the neuron membrane, a change that opnes
adjacent channels and propagates its flow.
The difference between weak and strong stimulus - ANSWERthe axon fires at a
greater frequency for an intense stimulus
The enzyme that breaks down acetylcholine - ANSWERacetylcholineesterase
Hepatic Portal Vein - ANSWERthe structure that absorbs nutrients from the small
intestines and delivers the nutrients in the blood to the liver
Sinoatrial node - ANSWERThe pacemaker of the cardiac conduction system
Hypertension - ANSWERCardiovascular disease is cuased by a narrowing of the
arteries causing the heart to work harder during pumping
Vena Cava - ANSWERBlood passes this structure immediately before entering the
right atrium
Atrioventricular valve - ANSWERWhich structure does blood pass through
immediately before it enters the left ventricle?
Arteries - ANSWERBlood vessels that carry blood away from the heart
Capillaries - ANSWERWhich blood vessels will have walls only one cell thick?
Nerve - ANSWERcomposed of the long fibers of long axons
Hot - ANSWERNot 1 of the 4 types of taste
Iris - ANSWERThe structure that regulates the size of the opening for light in the eye
Loudness - ANSWER"Cochlea tsunami"
The fluid in the cochlea vibrates with more force and this causes the basiliar
membrane to move more up and down with greater force
Farsighted - ANSWEReyeball is too short
nearsighted - ANSWERlight rays are brought into focus in front of the retina
, Pregnancy occurs - ANSWERthe developing embryo implants itself in the
endometrium
HCG - ANSWERPregnancy tests detect the presence of this hormone in the urine
Adaptive Radiation - ANSWEREx. Charles Darwin's Finches
A process in which organisms diversify rapidly into a multitude of new forms,
particularly when a change in the environment makes new resources available and
opens environmental niches
Speciation - ANSWERthe evolutionary process by which new biological species
arise
Ex. Marisupals
Kangaroo to Taz Devil transformation (eating other kangaroos) and Possums
genetic drift - ANSWERchance
non random mating - ANSWERas the name says?
Alleles - ANSWERalternative forms of gene that influence the same trait and are
found at the same location in homologous chromosomes
Mendel's Law of Seperation - ANSWERTwo members of an allele pair are distributed
to separate gametes
Recessive phenotype - ANSWERgenotype can only be tt
Law of Independent Assortment - ANSWERIf pairs of factors separate independently
of other pairs of factors
a gamete of the parent - ANSWERIf the genotype of an organism is YySsTt then
yST would represent
RrYy x RrYy - ANSWERCross that will yield four phenotypes in a 9:3:3:1 ratio
Multiple alleles - ANSWERthe inheritance of blood types in humans
Blood type O - ANSWERA man with blood type AB could NOT be the father of a
child with...?
incoming sensory nerve impulses are lost - ANSWERwhen the dorsal root of the
spinal nerve is cut
primary functions of the spinal cord - ANSWERreflex actions
communication between the brain and peripheral nerves
medulla oblongata - ANSWERPart of the brain that contains centers for the heart
beat and respiration
