What is happening in this picture? [if you cannot see the picture, refer to 'dragonflies' on the screen]
(The picture is dragonflies in the circular shape with the tails near the head) - Correct Answers The two
dragonflies are mating with each other.
The atmosphere of the early Earth did not contain O2. Where did the O2 eventually come from? -
Correct Answers Photosynthetic organisms released the O2.
Which of the following statements about dragonflies is false? - Correct Answers Dragonflies can
severely sting you, if you touch them.
According to scientific evidence, approximately how long ago did Earth form?
When did birds first show up in the fossil record? - Correct Answers 4.6 billion years ago , 150 million
years ago
When dragonflies are not flying, they sit with their wings widely spread rather than folding them back as
most other winged insects do. Why? - Correct Answers They have primitive wing morphology without a
hinge to fold the wings back.
One student earned an 80% in the lab-portion and a 100% for the discussion. What is the combined
lab/discussion grade for this student?
Their friend put a lot of effort in the lab portion and achieved 100% of the lab-points. However, they
missed 3 of the 15 discussions unexcused and got therefore an 80% discussion score. What is the
combined Lab/Discussion score of this student ? - Correct Answers 80% , 80%
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? [if you cannot see the figure,
refer to "diffusion" on the screen] - Correct Answers All directions are equally likely
,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? - Correct Answers Most minerals
wouldn't exist
Which of the following statements best describes the distribution of major events in the history of life
on Earth? - Correct Answers 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.
According to hiring managers of large companies, what is the most important characteristic of college
graduates that they consider to hire? - Correct Answers They are well able to work with others and
appreciate working in diverse groups.
Suppose you put a drop of lime flavoring into a glass of water. When you drink the water later, the flavor
has spread throughout the water, rather than remaining in the spot where you deposited it. Why? -
Correct Answers because the flavor molecules are moving, and some will end up moving into each part
of the glass
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 individual dye molecules at the time you return? - Correct Answers They're still moving in the same
manner as when they were dropped into the tank.
What is an adaptation in the context of evolution? - Correct Answers A trait produced by natural
selection
A biologist surveys a population consisting of 400 lizards, of which 100 are gray and 300 are black. The
color of a lizard is determined by which allele it has for a particular gene. Two hundred years later,
another biologist surveys the same population of lizards. Which of the following counts would indicate
that the population has evolved? - Correct Answers 300 gray and 600 black
On a bright summer day, most plants turn their chloroplasts away from the Sun to slow down
photosynthesis instead of using the energy in the sunlight to produce glucose. What is the reason for
this unexpected behavior? - Correct Answers Too much O2 would be produced in the chloroplasts,
which would damage the molecules involved in photosynthesis
, Which of the following situations typically selects for smaller body size in mammals? - Correct Answers
living in an environment with limited food supplies
At the end of the light-dependent reactions of photosynthesis, where is the energy from the sun
located? - Correct Answers In the chemical bonds of ATP molecules
A population of horned lizards lived for a long time in a valley without shrikes (=predators). Shrikes
arrived and now lizards with longer horns were at an advantage. After a few years, the average horn
length of the lizards had significantly increased.
When did the mutations that lead to the longer horn length happen? - Correct Answers Most of them
happened before the shrikes arrived
Which of the following would be an example of the First Law of Thermodynamics? - Correct Answers A
dark-colored driveway becomes too hot to touch when exposed to strong sunlight in the summer.
Which of the following assessment questions would be categorized at the 'Applying' level in Bloom's
taxonomy? - Correct Answers Given what you have learned about how the Corona virus gains access to
cells, describe a potential treatment that could block the virus from getting in.
D'Angelo is studying how tissues of the body differ in susceptibility to infection by the virus that causes
COVID. He exposes samples of muscle, epithelial, nervous, and connective tissues to a standard quantity
of virus particles, and then measures the percentage of cells in each tissue type that become infected.
Which of the following types of graph is D'Angelo most likely to use to represent the data? - Correct
Answers Bar graph
One of your instructors has one daughter with a lot of "pride" (=rainbow) things in their room. Among
other things, she has a rainbow light chain, with the different bulbs producing violet, blue, green, yellow,
orange, and red light. How does the electromagnetic radiation from the various light bulbs differ? -
Correct Answers wavelength
Why do cells perform photosynthesis? - Correct Answers To make glucose
The great oxygenation event was caused by (choose the best answer): - Correct Answers Cyanobacteria
evolved photosynthesis, which released free O2 into the oceans and atmosphere for the first time
