Document Content and Description Below

 BIO201L LAB ONLY_V2  Lab 3 Mitosis and Meiosis Started on Tuesday, March 29, 2022, 1:53 PM State Finished Completed on Tuesday, March 29, 2022, 2:00 PM Time taken 7 mins 22 secs Grade 35.... 00 out of 35.00 (100%) Question 1 Correct 3.50 points out of 3.50 Flag question Question text What is the outcome of crossing over? Select one: a. Increased species diversity. b. Decrease species diversity. c. Mutated DNA. d. There is no outcome because the DNA that underwent crossing over is returned to its original sequence before expression. Question 2 Correct 3.50 points out of 3.50 Flag question Question text The diversity in the DNA found in otherwise similar organisms is: Select one: a. Ploidy b. Homologous Chromosomes c. Genetic Variation d. Alleles Question 3 Correct 3.50 points out of 3.50 Flag question Question text Which of the following statements reflects the results of meiosis I and meiosis II? Select one: a. Meiosis I produces two haploid cells, while meiosis II results in two diploid cells. b. Meiosis I produces two haploid cells, while meiosis II results in four haploid cells. c. Meiosis I produces four haploid cells, while meiosis II results in two haploid cells. d. Meiosis I produces two diploid cells, while meiosis II results in four diploid cells. Question 4 Correct 3.50 points out of 3.50 Flag question Question text The exact position of a gene on a chromosome is the chiasmA. Select one: a. True b. False Question 5 Correct 3.50 points out of 3.50 Flag question Question text Human somatic cells are: Select one: a. Polyploid b. Diploid c. Haploid d. Hexaploid Question 6 Correct 3.50 points out of 3.50 Flag question Question text In mitosis, one set of chromosomes arrives at each pole during prophase. Select one: a. True b. False Question 7 Correct 3.50 points out of 3.50 Flag question Question text Which of the following does NOT occur during metaphase? Select one: a. Sister chromatids migrate towards the metaphase plate. b. Microtubules grow from the centrioles and attach to sister chromatids. c. Microtubules attach to centromeres and other microtubules from opposite poles. d. Microtubules attached to the centromeres begin to shorten. Question 8 Correct 3.50 points out of 3.50 Flag question Question text How does cell division differ between plant and animal cells? Select one: a. Plant cells must have a certain number of chloroplasts before they can divide. This is not a requirement in animal cells. b. In animal cells, the plasma membrane folds and encloses each nucleus to create two diploid cells, whereas in plant cells, a new cell wall must be developed that will separate the two cells. c. Plant cells cannot divide, due to their rigid cell wall. d. There is no difference in cell division between plant and animal cells. Question 9 Correct 3.50 points out of 3.50 Flag question Question text Which of the following is true about the length of the cell cycle? Select one: a. A cell normally undergoes the cell cycle in 24 - 36 hours, of which mitosis occupies 4 - 8 hours. b. A cell normally undergoes the cell cycle in 24 - 36 hours, of which mitosis occupies 1 - 2 hours. c. A cell normally undergoes the cell cycle in 18 - 24 hours, of which mitosis occupies 4 - 8 hours. d. A cell normally undergoes the cell cycle in 18 - 24 hours, of which mitosis occupies 1 - 2 hours. Question 10 Correct 3.50 points out of 3.50 Flag question Question text Suppose you are examining a pair of chromosomes that encode the same genes and the exact same alleles. What type of chromosomes are these? Select one: a. Homologous Chromosomes b. Heterozygous Chromosomes c. Sister Chromatids d. Daughter Chromatids [Show More]
