Question 1

Question

Which claim is an evolutionary advantage of asexual reproduction over sexual reproduction?

a
Asexual reproduction can increase the population in a very short amount of time.
b
Asexual reproduction requires only meiosis.
c
Asexual reproduction can produce a variety of individuals.
d
Asexual reproduction requires many more steps than sexual reproduction.
Question 2

a
terrestrial during all life stages
b
mammary glands & hair
c
opposable thumbs
d
jaws
Question 3
In the mid-1600s, Francesco Redi performed a classic experiment to test the concept of spontaneous generation. As a control, he placed rotten meat in two open containers. The experimental jars also contained rotten meat, but he covered the openings with pieces of cloth. Flies landed on the meat in the open jars, but were not able to reach the meat under the cloth. Over time, maggots covered the meat in the control jars, but no maggots appeared in the experimental jars. Which of the following did Redi's results most likely show?

a
Rotten meat produces maggots.
b
Flies are not able to develop in jars.
c
Maggots are produced by adult flies.
d
Spontaneous generation occurs in open jars.
Question 4
Read the passage about punctuated equilibrium.


The theory of punctuated equilibrium states that many species did not evolve for thousands of years. Instead, evolution took place when environmental conditions shifted, causing individuals to be in more extreme competition with one another. The theory of punctuated equilibrium is supported by fossil evidence of many periods of stasis.

Which of the following statements does the theory of punctuated equilibrium challenge?

a
Many organisms share a common ancestor.
b
Many species remain in stasis for long periods of time.
c
Evolution is a gradual process taking place in a stable environment.
d
Evolution occurs in groups of organisms through natural selection.
Question 5
According to Charles Darwin, which species is least likely to survive?

a
the species that is the most aggressive
b
the species that has no natural predators
c
the species that is the smallest
d
the species that is least adapted to its environment
Question 6
If a population experiences no migration, is very large, has no mutations, has random mating, and there is no selection, which of the following would you predict?

a
Dominant alleles in the population's gene pool will slowly increase in frequency while recessive alleles will decrease.
b
The population will evolve, but in a punctuated equilibrium like fashion.
c
The composition of the population's gene pool will change slowly in a predictable manner.
d
The makeup of the population's gene pool will remain virtually the same as long as these conditions hold.
e
The population probably has an equal frequency of A and a alleles.
Question 7
Using the Hardy-Weinberg principle, if p = 0.3, what is q?

a
0.3
b
0.5
c
0.7
d
1.0
Question 8
Hardy-Weinberg Equilibrium - ScienceAid

a
q=0.04; p=0.16
b
q=0.2; p=0.8
c
q=0.8; p=0.2
d
q=0.1; p=1.0
Question 9
Hardy-Weinberg Equilibrium - ScienceAid

a
q=0.2; p=0.8
b
q=0.04; p=0.16
c
q=0.1; p=1.0
d
q=0.8; p=0.2
Question 10
Patty's prescription antibiotic suggests that she take it for fourteen days. If she stops taking the medication after ten days, what could happen to the bacteria in Patty's body?

a
It could cause her immune system to stop producing antibodies altogether.
b
It could allow her immune system to build up resistance to that strain of bacteria forever.
c
It could build up a resistance to all antibiotics, turning into a "superbug".
d
It could build up resistance to the antibiotic rendering the rest of the medication useless.

Answer 1

Here are the answers to your questions:

Question 1:
a Asexual reproduction can increase the population in a very short amount of time.

Question 2:
c opposable thumbs

Question 3:
c Maggots are produced by adult flies.

Question 4:
c Evolution is a gradual process taking place in a stable environment.

Question 5:
d the species that is least adapted to its environment

Question 6:
d The makeup of the population's gene pool will remain virtually the same as long as these conditions hold.

Question 7:
c 0.7 (since p + q = 1, if p = 0.3, then q = 1 - 0.3 = 0.7)

Question 8:
I would need the specific values for p or q to answer this question accurately, or it can be inferred that none of the provided options is directly calculable without knowing additional specifics.

Question 9:
Again, I would need the specific values for p or q to answer directly, or the options may not match a standard Hardy-Weinberg calculation.

Question 10:
d It could build up resistance to the antibiotic rendering the rest of the medication useless.
