1) the genetics inherited by an individual will completely control their behavior.
2) male birds often perform a special dance or set of physical displays to attract
females. this would be an example of a behavioral isolation mechanism.
3)
the cylinders in this experiment represent a 24-hour period. the light area represents
light periods during a 24-hr. period and the dark area represents dark periods during a
24-hr. period. the critical length of dark vs. light periods for flowering is depicted by the
dotted line. note that some plants are flowering and some are not flowering.
the conclusion drawn from these results is that the length of the dark period, not the
light period, controls flowering.
4) a decrease in the over fishing of herring and perch would have prevented the
decimation of the kelp beds along the west coast of the u.s..
5) a unit of a chromosome that consists of dna wound around a core of eight histone
proteins is a transposon.
6) a change of one ph unit represents a ten-fold increase or decrease in hydroxyl ion
concentration.
7) the scale ranges from 1 to 15.
8) the correct number of chromosomes in a species is known as aneuploidy
9) ph 7 has a balanced level of h+ and oh-.
10) a diet high in omega-3 fatty acids obtained from various types of fishis
recommended to reduce the risk of cardiovascular disease.
11) in order to roll a rock down a hillside, you must first push it up out of the hole in
which it rests. pushing the rock is analogous to the energy of activation of a chemical
reaction.
12) biodiversity is described in terms of genetic, community, and landscape diversity.

a. parapodia
b. tracheoles
c. body surface

d. 12 & 6
e. oxaloacetate

a. monoclonal antibodies
b. agglutination factors
c. autoimmune agents
d. immunosuppressant agents
e. allergen antibodies
16) cytokinesis in plant cells differs from this process in animal cells because
a. the plant endoplasmic reticulum forms a cell plate.
b. microtubules are laid down in a plywood-like cell plate pattern.
c. the golgi apparatus produces vesicles that migrate along microtubules and fuse to
become a cell plate.
d. the inner plasma membrane divides by cytokinesis as in animal cells and then
secretes a cellulose cell wall.
e. asters coalesce to form a fibrous plate that reinforces with cellulose.
17) what structure will code for theproteins that will promote the normal cell cycle and
prevent apoptosis?
a. tumor suppressor genes
b. oncogenes
c. caspases
d. proto-oncogenes
18) which of the following associations of term and description is not correct?
a. actin – thin filament
b. myosin – thick filament
c. sarcomere – the entire muscle cell or muscle fiber
d. sarcolemma – extensive plasma membrane
19) if a plant contains seven bundle scars this would indicate that the plant is ______
years old.
a. four
b. seven
c. fourteen
d. you cannot tell the age of a plant by the number of bundle scars.

b. auditory communication
c. tactile communication
d. visual communication
21) which type of tissues would be damaged if someone was in a car accident and they

b. pseudostratified ciliated epithelium, cuboidal epithelium, smooth muscleand neural
tissues
