BIO 1500 (BUSH MIZZOU) FINAL EXAM QUESTIONS AND ANSWERS ALREADY PASSED
Roughly how old are the oldest fossils on Earth? - Answers 3.8 billion years
According to scientific evidence, approximately when did Earth form? - Answers 4.6 billion years
ago
How long did dinosaurs roam on Earth? - Answers about 180 million years
According to the fossil record, which was first on earth, dragonflies or dinosaurs? - Answers
dragonflies
Which statement about dragonflies is true? - Answers 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 -
Answers 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? - Answers 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? - Answers 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? - Answers 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? -
Answers 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? - Answers 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? - Answers 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: - Answers increase the mass of the dye molecules
in your reading assignment, "The Pen is Mightier than the Keyboard", the authors conclude that
students who take notes by hand tend to out-perform students who take notes with a computer
when tested on the material. What was their explanation for the benefit of writing notes by hand?
- Answers students think about the material more when they take notes by hand than when they
type
What is the function of photosynthesis? - Answers to make carbohydrates
Two different forms of genes are - Answers alleles
Both Oreo cookies and Fig Newton cookies contain 1g of dietary fiber per serving. This fiber, or
roughage, typically consists of cellulose. Given this information, 'dietary fiber' is likely to be
listed under which of the following headings? - Answers carbohydrates
the instructor of your bio 4600 "Evolution" course comes into class one morning very excited
and announces: "My fitness has increased!" What has happened to her? - Answers Her daughter
gave birth to a healthy baby
over spring break one of your friends back home says, "It is ridiculous to believe that complex
organisms could have evolved through natural selection: how could this all happen by random
events?" What would be the best reply to this misconception? - Answers While several
evolutionary mechanisms are indeed random, natural selection is not; it increases the frequency
of alleles associated with favorable traits
the great oxidation event was caused by - Answers cyanobacteria evolved photosynthesis,
which released free O2 in the oceans and atmosphere for the first time
when you shine white light on chlorophyll extract, the outside of the liquid turns red. Which
