Question 8

 B)False

Question 9

Which statement best expresses the major difference between mitosis and meiosis?

Accepted Answer

A) Mitosis is cell division in animals;meiosis is cell division in humans. 
B) Mitosis is the process by which a single cell with X number of chromosomes divides into two cells,each with the same number of chromosomes;meiosis is the process by which a single cell with X number of chromosomes goes through two stages of division,producing four new cells each with X/2 (half the original number)of chromosomes. 
C) Mitosis is the process by which chromosomes are divided;meiosis is the process by which DNA is divided. 
D) Mitosis is the process by which cells divide into four different sets of genetic information (called codons);meiosis is the process by which cells are joined together and multiplied to create growth and development. 
E) Mitosis and meiosis are both types of cell division in which a single cell with X number of chromosomes divides into two cells,each with one half of the original chromosomes;mitosis is associated with the creation of sex cells that determine the sex of the offspring,and meiosis is associated with cell growth and development.
