classify the following question in Bloom's taxonomy: "use
your knowledge of cellular processes to explain why organisms
that were capable of performing cellular respiration spread
rapidly around the planet following the Great Oxygenation
Event." According to Bloom's, this question is at the level of: -
ANSWER-applying
Larger individuals often have advantages that lead to selection
for larger body size. Which of the following is typically NOT an
advantage of being larger than other members of your species?
- ANSWER-You are less likely to be killed by a predator
when people preserve their own veggies, it is important to heat
the sealed jars to a high enough temperature to kill the bacteria
that cause botulism. The botulism bacteria thrive in sealed food
containers with no O2. Based on this, what can you conclude
about the bacteria? - ANSWER-they perform glycolysis, but not
the citric acid cycle
which of the following statements about the relationship
between PS and CR is
,true? - ANSWER-plants perform PS as
well as CR
during glycolysis, a glucose molecule is split into: -
ANSWER-two pyruvate
molecules
what is the function of the Electron Transport Chain in CR?
- ANSWER-to
establish a concentration gradient
of protons
as electrons pass through the electron transport chain, they
ultimately end up
on the final receptors, which is -
ANSWER-oxygen
why don't insects need to transport O2 in their blood like
mammals do? - ANSWER-O2 diffuses through hollow tubes
directly to every cell in the insect body
a particular type of rat poison works by inhibiting the ability
of the rat cells to
perform CR. Given this information, why do rats who have
eaten the poison
die? - ANSWER-they lack
sufficient ATP
, researchers want to test whether high 02 levels in the
atmosphere lead to the evolution of larger body size and
insects. They set up two conditions, one hyperoxic condition
with 35% O2 and one control group with 21% 02 (which is the
current level of O2 in the atmosphere). Otherwise the
conditions were identical. There is fruit flies in both conditions
for 10 generations. They took the 10th generation out of the two
oxygen levels and measure the weight of the fruit flies in the
two groups. They found out that the fruit flies under hypoxic
conditions were significantly larger than the ones under the
control conditions. The researchers concluded that the fruit
flies evolved a larger body size under hyperoxic conditions.
Is this a valid conclusion based on the experiment? Which
of the following
statements is the most accurate? - ANSWER-no, the
conclusion cannot be
drawn, because they do not test whether the size increase had
a genetic basis
Consider the experiment in the previous question: which would
be the best way
to improve this experiment? - ANSWER-add an 11th
generation where both
groups are the same conditions of 21%
oxygen levels
researchers surveyed 12,000 kids between fifth and eighth
grade and asked them how many times per week They ate fast
