Living Environment:Mitosis / Asexual Reproduction: 10 Questions
1. Which statement best describes a population of organisms if cloning is the only method used
to reproduce this population?
(1) The population would be more likely to adapt to a changing environment.
(2) There would be little chance for variation within the population.
(3) The population would evolve rapidly.
(4) The mutation rate in the population would be rapid.
2. A pattern of reproduction and growth in a one-celled organism is
shown below.
Which statement best describes this pattern of reproduction?
(1) All genetic material comes from one parent.
(2) Only some of the genetic material comes from one parent.
(3) The size of the parent determines the amount of genetic material.
(4) The size of the parent determines the source of the genetic material.
3. A technique used to reproduce plants is shown in the diagram below.
This technique is a form of
(1) sexual reproduction
(2) asexual reproduction
(3) gamete production
(4) gene manipulation
4. A certain bacterial colony originated from the division of a single bacterial cell. Each cell in
this colony will most likely
(1) express adaptations unlike those of the other cells
(2) replicate different numbers of genes
(3) have a resistance to different antibiotics
(4) synthesize the same proteins and enzymes
5. The diagram below represents single-celled organism A dividing by mitosis to form cells B
and C.
Cells A, B, and C all produced protein X. What can best be inferred from this observation?
(1) Protein X is found in all organisms.
(2) The gene for protein X is found in single-celled organisms, only.
(3) Cells A, B, and C ingested food containing the gene to produce protein X.
(4) The gene to produce protein X was passed from cell A to cells B and C.
6. The diagram below represents the cloning of a carrot plant.
Compared to each cell of the original carrot plant, each cell of the new plant will have
(1) the same number of chromosomes and the same types of genes
(2) the same number of chromosomes, but different types of genes
(3) half the number of chromosomes and the same types of genes
(4) half the number of chromosomes, but different types of genes
Base your answers to questions 7 through 10 on the diagram below and on your knowledge of
biology. The diagram represents a single-celled organism, such as an ameba, undergoing the
changes shown.
7. As a result of these processes, the single-celled organism accomplishes
(1) gamete production
(3) sexual reproduction
(2) energy production
(4) asexual reproduction
8. Process 1 is known as
(1) replication
(2) meiosis
(3) differentiation
(4) digestion
9. Process 1 and process 2 are directly involved in
(1) meiotic cell division
(3) fertilization
(2) mitotic cell division
(4) recombination
10. The genetic content of C is usually identical to the genetic content of
(1) B but not D
(3) D but not A
(2) both B and D
(4) both A and D
