BIO 1500 FINAL MIZZOU CERTIFICATION
STYLE ASSESSMENT COMPLETE QUESTIONS
WITH VERIFIED SOLUTIONS
●● According to scientific evidence, approximately when did Earth
form?
Answer: 4.6 billion years ago
●● How long did dinosaurs roam on Earth?
Answer: about 180 million years
●● According to the fossil record, which was first on earth, dragonflies
or dinosaurs?
Answer: dragonflies
●● Which statement about dragonflies is true?
Answer: a. During their lifecycle, dragonflies spend several years in
water
b. adult dragonflies can only feed while they are flying, because they
need all their legs to hold their prey. They starve if they cannot fly
c. Dragonflies have no changed much in appearance for hundreds of
millions of years
d. During their larval stages, dragonflies often eat fish and tadpoles.
,e. all of the above
e. all of the above
●● About 100 million years ago, the max wingspan of dragonflies
decreased while the oxygen level in the atmosphere stayed constant.
Clapham and Karr attribute this drop in dragonfly size to
Answer: the evolution of modern bird traits, which improved their flight
performance
●● According to the paper by Clapham and Karr, which evidence
supports the conclusion that oxygen levels in the atmosphere limit the
max size of dragonflies?
Answer: During the Carboniferous, dragonfly size increased with rising
oxygen levels and decreased when oxygen levels went down
●● According to members of medical school selection committees, what
is the most important characteristic of incoming med-school students?
Answer: they take an active role in shaping their own learning
experience
●● According to scientific evidence, which of the following statements
best describes the history of life on Earth?
, Answer: although life began relatively soon after the Earth cooled, most
major evolutionary changes occurred in the most recent quintile of
Earth's history
●● According to your reading assignment, how does facilitated differ
from simple diffusion?
Answer: in facilitated transport, the substance passes through a pore, or
tunnel, inside other molecules in the membrane
●● a drop of blue dye is released into the left side of a tank of water. The
molecule of blue dye gradually disperse among the molecules of water
in the tank. If you could identify one molecule of dye and observe how it
moves, which of the following statements would best describe its
behavior after it is introduced into the water?
Answer: it is equally likely to move to the left vs right
●● when considering all of the molecules of blue dye in the tank, why
do they end up relatively evenly distributed throughout the water?
Answer: as a matter of probability, more dye molecules will move to an
area with fewer of them, than vice versa
●● suppose you are developing a new dye that will enter cells through
diffusion across the plasma membrane, enabling you to see the cells
more easily under a microscope. If you want to increase the rate of
diffusion fo the dude molecules into the cells, you might try all of the
following EXCEPT:
