In a population of small homeotherms (endotherms), a mutation arises that results in the inner mitochondrial membrane having fewer folds(see page 3). A scientist measures the total length of the membrane within 10 members each of the two different types of animals. He finds that in the less folded membrane (animal type LF) the length is at about one-third that of the more folded membrane (animal type MF).
Based on the above finding he would correctly predict which one of the following? Top of Form
a) Animal type LF is capable of producing more ATP than animal type MF
b) Animal type MF is capable of producing more ATP than animal type LF.
c) There is no difference in the amount of ATP produced by the 2 types of animals.
d) Glycolysis does not occur in animal type LF.
e) Glycolysis does not occur in animal type MF.
Which of the following observations provide the best evidence for the Endosymbiotic Theory of the origin of Eukaryotes?
a) Most bacteria are much larger than mitochondria and chloroplasts.
b) Prokaryotes, mitochondria, and chloroplasts all have cell walls.
c) Prokaryotes, mitochondria, and chloroplasts all have DNA and ribosomes.
d) Prokaryotes, mitochondria, and chloroplasts cannot reproduce themselves.
e) Prokaryotes, mitochondria, and chloroplasts are not surrounded by membranes.
Boomer Lake with _______ nitrate and phosphate concentrations would be likely to have a lower concentration of dissolved oxygen during the __________.
a) high; day

In a particular population of 100 prairie dogs living in 100 acres, growth rate (r) = 0.1 prairie dogs/prairie dog/year.
[14] For this population, what is a possible combination of b and d?
a) b = 200 births/100 individuals/year and d = 190 deaths/100 individuals/year
b) b = 200 births/100 individuals/year and d = 200 deaths/100 individuals/year
c) b = 190 births/100 individuals/year and d = 200 deaths/100 individuals/year
d) b = 500 births/100 individuals/year and d = 400 deaths/100 individuals/year
e) none of the above are correct

Beginning of year # # ants
1 500
2 600
3 720
What would the expected ant population size (N) be at the end of the 3rd year (beginning of the 4th year)? ï answer: _____ants
a) 144 b) 744 c) 840 d) 864 e)1320
