8) Which of the following is an advantage of asexual reproduction?
A
It is a slow process.
B
The organism can increase in number quickly.
C
Two parents are needed.
D
It introduces genetic diversity in the offspring.
9) Which of these statements is true of asexual reproduction?
A
It produces offspring genetically different from each other and requires two parents.
B
It produces offspring genetically identical to each other and requires one parent.
C
It produces offspring genetically identical to each other and requires two parents.
D
It produces offspring genetically different from each other and requires one parent.
10) Which of these statements correctly describes one way that asexual and sexual reproduction are different?
A
Asexual reproduction increases genetic diversity, but sexual reproduction does not.
B
Asexual reproduction involves one parent, and sexual reproduction involves two parents.
C
The offspring produced by asexual reproduction are not identical to each other, but those of sexual reproduction are identica
D
Asexual reproduction increases a species’ chances of surviving unfavorable conditions, but sexual reproduction does not.
11) Which of these statements is true for organisms that reproduce asexually?
A
organisms that reproduce asexually are less likely to expend energy caring for their offspring.
B
organisms that reproduce asexually are more likely to have offspring genetically different from themselves.
C
organisms that reproduce asexually are less likely to require only one parent for reproduction to take place.
D
organisms that reproduce asexually are more likely to expend energy to find a mate.
12) Which of these statements correctly describes one way that asexual and sexual reproduction are alike?
A
Both types of reproduction require two parents to produce offspring
B
Both types of reproduction can occur in all organisms, depending on environmental conditions
C
Both types of reproduction result in offspring that are identical to one parent.
