Bradley decides one day to run a marathon without any training. After ten minutes has elapsed
and Bradley has run half a mile, he begins to get cramps in his thighs. He is also breathing very
rapidly. What is causing the cramps on Bradley's legs? ✔✔Lactic acid buildup in his muscles
due to a lack of oxygen to his cells.
The leopard frog and the pickerel frog are two
closely related species. In areas where
their ranges overlap, the frogs will remain
separate species if they ✔✔reproduce at different times of the year.
The Hardy-Weinberg equilibrium model states that allele and genotype frequencies in a
population will remain constant from generation to generation in the absence of other
evolutionary influences. Because one or more of the influences listed above are typically present
in real populations, the Hardy-Weinberg model describes an ideal condition against which the
effects of these influences can be analyzed. Of the influences listed, which would not cause a
change in allelic frequencies or genotype? ✔✔Mitotic division
Consider the graphic of the divergence of one founder species into many additional bird species.
This speciation resulted in ✔✔biodiversity due to anatomy and available food resources.
Bacteria, like the Lactobacillus acidophilus use sugar as an energy source for anaerobic cellular
respiration. This process produces much less ATP than aerobic respiration and does not produce
carbon dioxide as a by-product. It does, however, give yogurt its sour taste and prevents other
food spoiling bacteria from developing. ✔✔lactic acid fermentation.
Before organisms with nuclei evolved, life on earth consisted only of unicellular
✔✔prokaryotes.
Read the prompt and study the diagram. What cause and effect prediction can be used to test the
assumptions in the model? ✔✔with more sunlight more sugar will be produced by the plant
Why are the apple farmers seeing these new, stronger bugs? ✔✔The strongest bugs were able to
survive pesticides, reproduce and create more resistant pests.
, One difference between mitochondria and chloroplasts is ✔✔mitochondria produce water from
oxygen while chloroplasts produce oxygen from water.
While studying the classification of living things you are given a specimen that has cell walls.
The ONLY kingdom you can rule out immediately is ✔✔animal
Compare and contrast the rate of photosynthesis is the two areas. Give a reason for your answer
based on the scenario. ✔✔Photosynthesis and radiant energy transfer are affected by natural
insulation such as clouds. The area on the left has more greater natural insulation and we would
expect a lower rate of photosynthesis.
Which molecule in the picture is most favored by mitochondria and used by the body as quick
energy? ✔✔glucose
The dots represent a bacterial infection. Sal was very sick with this bacterial infection. The
infection was treated with antibiotics. Sal seemed to get well, but in a few weeks, she was sick
again. How can this be explained using natural selection? ✔✔The stronger, more resistant
bacteria survived the antibiotics and reproduced.
Considering the new definition of life, all but one piece evidence supports the fact that a virus
must be referred to as an organism. That is: ✔✔Viruses have a simple cellular structure.
Recent work in classification of life on Earth has shown that what were once called prokaryotes
are much more diverse than ever suspected. The prokaryotae are now divided into two domains,
the Eubacteria and the Archaeabacteria, as different from each other as either is from the
Eukaryota. One organism, the blue-green algae or cyanobacteria, has left a fossil record that
dates back nearly 3.5 billion years and is among the oldest fossils known. These blue-green algae
had cell walls and were photosynthetic. A few hundred years ago, this organism was classified as
a plant, then as a protist. Today it is classified in the Eubacteria because it ✔✔is prokaryotic.
Based on the data given, what is the BEST conclusion to be drawn? ✔✔Over time, due to
evolution by means of natural selection, resistant weeds survived, reproduced, and passed on
their herbicide resistant genes.
The graph shows levels of primary and secondary immune responses versus time. The secondary
response is greater and more rapid than the primary response. What does the graph BEST
