Test Bank: Biology , 11th Edition by Solomon - Chapters 1-57,9781337392938 | Rationals Included
Some fungi can reproduce either asexually or sexually, resulting in offspring with different
characteristics. Sexually produced offspring have:
A. a complex level of cell organization.
B. a number of organelles in each cell.
C. a lesser risk of having mutations than asexually produced offspring.
D. a combination of genetic material from each parent cell. - ANSWER:D
Daffodils are plants that can perform both asexual and sexual reproduction. How does a daffodil
population benefit more by reproducing sexually than asexually?
A. It can reproduce more rapidly.
B. It can adapt faster to its environment.
C.It can increase the diversity of inherited traits.
D. It can eliminate unfavorable traits from the gene pool. - ANSWER:C
Which is the greatest benefit of sexual reproduction?
A. capable of reproducing by meiosis
B. ability to reproduce without a mate
C. ability to produce genetically different offspring
D. capable of producing offspring genetically identical to parent - ANSWER:C
Potatoes reproduce by growing sprouts on their surfaces. When planted, these sprouts grow into new
plants. This is an example of
A. seed production.
B. fertilization.
C. pollination.
D. asexual reproduction. - ANSWER:D
Meiosis is a type of cell division in which germ cells divide to produce haploid cells. Where does
meiosis occur?
A. brain cells
B. bone cells
C. muscle cells
D. ovary cells - ANSWER:D
Which of these is the best example of sexual reproduction?
A. binary fission
B. budding
C. fusing gametes
D. fragmentation - ANSWER:C
A main advantage to organisms that reproduce sexually is:
A. being able to conserve energy.
B. having large numbers of offspring.
C. greater genetic diversity.
D. longer life spans. - ANSWER:C
Nondisjunction during meiosis results in an abnormal number of chromosomes in one or more
gametes. In some cases of nondisjunction, a single chromosome fails to separate. In others, none of
the chromosomes separate. Suppose an egg is produced in which none of the chromosomes separate
during meiosis II. What is the chromosome number of the zygote that results if this egg is fertilized by
a normal sperm?
A. 1n
B. 2n
, C. 2n + 1
D. 3n - ANSWER:D
The gametes of human males and females have the same number of chromosomes. Which best
describes what happens to the chromosomes when typical male and female gametes combine to
produce offspring?
A. The chromosomes change shape.
B. The number of chromosomes doubles.
C. The chromosomes become larger in size.
D. The number of chromosomes reduces by half. - ANSWER:B
Onions can reproduce from bulbs. One parent bulb generates daughter bulbs with duplicate genetic
information. Which is the most likely advantage of this kind of reproduction?
A. Population size remains constant.
B. Beneficial mutations are inevitable.
C. Genetic variation is maximized.
D. Large quantities of individuals can be produced rapidly. - ANSWER:D
An animal's somatic cells contain 2n chromosomes. What happens to the number of chromosomes in
the animal's gametes?
A. The number is reduced to n by mitosis.
B. The number is reduced to n by meiosis.
C. The number is increased to 4n by mitosis.
D. The number is increased to 4n by meiosis. - ANSWER:B
Which of the following is a part of the process of sexual reproduction?
A. budding
B. regeneration
C. pollination
D. fragmentation - ANSWER:C
Potatoes can reproduce asexually. Each sprout on a parent potato can grow into a new potato
plant.How does the genetic material in the sprout compare to the parent potato?
A. The sprout has a random genetic assortment.
B. The sprout has twice the genetic material of the parent potato.
C. The parent potato has twice the genetic material of the sprout.
D. Both the sprout and the parent potato have the same genetic identity. - ANSWER:D
Which plant cells contain half the DNA from one parent plant?
A. xylem and phloem
B. pollen and ovule
C. epidermis and mesophyll
D. pith and cambium - ANSWER:B
What advantage do the offspring of a dandelion have by reproducing asexually?
A. Reproduction occurs rapidly.
B. Reproductive competition is increased.
C. Mating compatibily improves.
D. Diversity increases between generations. - ANSWER:A
Mitosis and meiosis are similar processes. Which best describes what can only occur after meiosis?
A. Parent cells can be either haploid or diploid.
B.Products of cell division result in identical genotypes.
C. Four daughter cells are produced by a single parent cell.
D. The number of chromosomes per nucleus remains the same after division. - ANSWER:C
Which of these is defined as "the passage of genetic instructions from one generation to the next?"
