Clapham and Karr conclude that although O2 concentration determined the maximum insect size during
the Carboniferous, other factors determined maximum insect size later in Earth's history. What evidence
led to this conclusion? - Around 120 million years ago oxygen levels increased while maximum
insect size did not.
Danielle, a student in Bio1500, worked very hard on the lab and has a Lab average of 100%. Because she
skipped several discussions without excuses, her average in the discussion is 75%. What is the combined
Lab*Discussion score which counts for 25% of the total Bio1500 grade? - 75%, because the two
grades are multiplied with each other
In the figure below from your video on diffusion, a red arrow points to an orange particle. In the next
instant of time, which direction is the orange particle most likely to move? - to the right
Which of the following statements about dragonflies is false? - Dragonflies feed on nectar and
pollen and are important plant pollinators
A drop of dye has been deposited at one end of a tank of water. If you leave the tank of water alone for a
long period of time (several days) and return to it later, which statement best describes the behavior of
the dye molecules at the time you return? - They're still moving in the same manner as when they
were dropped into the tank
You are standing in line for lunch in the Student center. You try to explain to one of your classmates how
much distance they should leave between you using what you learned about the size of Meganeura (the
giant dragonflies). How many Meganeuras should be able to fly side by side between two people in line
to maintain sufficient social distancing during the Covid-19 pandemic? - 2 meganeuras
The atmosphere of the early Earth did not contain O2. Where did the O2 eventually come from? -
Photosynthetic organisms released the O2.
Which of the following statements best describes the distribution of major events in the history of life on
Earth? - Major evolutionary milestones tend to be more highly concentrated at the recent end of
the timeline that extends from the origin of life until today.
, What is the logic behind Drs. Bush and Schul's system for assigning the teams? - Maximize
diversity of experience, background, majors, etc., because this increases the likelihood of the group
members to be successful
The atmosphere of the early earth lacked molecular oxygen. If O2 had never been added to the
atmosphere, what geological phenomenon would not have occurred? - Most minerals wouldn't
exist
Look at the formula below, which was in your lecture on diffusion. What important point is illustrated by
this formula?
t=x^2/2D t=time, x=distance, D=Diffusion coefficient - Small increases in the distance over which
particles travel by diffusion require large increases in the time for that diffusion to take place.
According to scientific evidence, approximately when did Life first appear on Earth? - 3.8 BYA
Approximately when did photosynthesis occur for the first time on Earth? - 2.5 BYA
When do mutations occur? - at random times
Trace the flow of energy during the reactions of photosynthesis. Energy enters photosynthesis in the
form of light energy . At the end of the light-dependent reactions, the energy is located in the bonds of -
light energy
Following the light-independent reactions, the energy is located - in the bonds of glucose
The great oxygenation event was caused by (choose the best answer): - Cyanobacteria evolved
photosynthesis, which released free O2 into the oceans and atmosphere for the first time
