Question 1
Question
Mitosis and meiosis are processes involved in cellular reproduction. Which of the following describes an event that results from mitosis but NOT meiosis?
Answer
-
Two stages of cell division
-
Replication of cellular genetic material
-
Daughter cells that are identical to the parent cell
-
Four daughter cells that are produced from each parent cell
Question 2
Question
Which type of reproduction leads to increased genetic variation in a population?
Answer
-
Parthenogenesis
-
Asexual reproduction
-
Sexual reproduction
-
Vegetative reproduction
Question 3
Question
Which of the following best compares the processes of mitosis and meiosis?
Answer
-
Mitosis involves one division cycle and results in diploid daughter cells, while meiosis consists of two division cycles and results in haploid gametes
-
Mitosis involves one division cycle and results in haploid gametes, while meiosis consists of two division cycles and results in diploid daughter cells
-
Mitosis involves two division cycles and results in diploid daughter cells, while meiosis consists of one division cycle and results in haploid gametes
-
Mitosis involves two division cycles and results in haploid gametes, while meiosis consists of one division cycle and results in diploid daughter cells
Question 4
Question
Which of the following best explains why meiosis results in greater genetic diversity than mitosis?
Answer
-
After meiosis, daughter cells are diploid and have twice as much genetic material, which can be divided in many more possible combinations
-
After meiosis, haploid daughter cells are fertilized, which doubles the number of chromosomes and increases the number of possible genes
-
During meiosis, chromosomes assort themselves independently of each other, which allows for more different possible combinations of chromosomes
-
During meiosis, more daughter cells are produced, which increases the likelihood that fertilization will occur
Question 5
Question
Which of the following occurs during mitosis?
Answer
-
The cell membrane pinches one cell into two
-
The chromosomes of the patient cell are copied
-
The parent cell takes in nutrients and doubles in size
-
The nucleus of the parent cell divides into two nuclei
Question 6
Question
In a single celled organism, mitosis is used for:
Answer
-
Development
-
Reproduction
-
Growth
-
Repair
Question 7
Question
Multicellular organisms use mitosis for growth, development and:
Answer
-
Apoptosis
-
Repair
-
Reproduction
-
Interphase
Question 8
Question
Why is it important for the daughter cells to divide a second time in meiosis?
Answer
-
The second division switches parts of matching chromatids to increase genetic variation
-
The second division forms four identical cells to ensure that all offspring have the same traits
-
The second division sorts chromosomes into cells that are the same as the parent cells
-
The second division forms haploid cells that can combine with other haploid cells during fertilization
Question 9
Question
What happens to sister chromatids in meiosis II?
Answer
-
They duplicate
-
They separate
-
They remain together
-
They do not take part
Question 10
Question
Which of the following describes how the process of crossing over during meiosis leads to an increase in genetic diversity?
Answer
-
During prophase I, DNA replication takes place and homologous chromosomes trade places with each other before lining up in preparation for metaphase
-
During prophase I, DNA segments are exchanged between homologous chromosomes resulting in different combinations of alleles
-
During prophase II, fragments of DNA break off of chromosomes and attach to the ends of other chromosomes, resulting in different gene sequences
-
During prophase II, sister chromatids separate from each other, and as they travel to oppsite ends of the cell, DNA segments of nearby chromosomes are exchanged
