D) duplication. 4.Which of the following statements about cell division is correct? A) It is the process by which organisms grow and maintain their tissues. B) It is no longer necessary once an organism reaches maturity. C) It occurs in two sequential stages in all cells: mitosis and meiosis. D) It is the process by which fertilization occurs. 5.Which set of symbols represents the stages of interphase? A) G0, G1, and G2 B) S1, S2, and G0 C) S, G0, and G1 D) S, G1, and G2 6.During the S phase, the cell A) duplicates its DNA. B) grows in size to prepare for DNA synthesis. C) completes its preparation for mitosis. D) rests between divisions. 7.The G0 phase of the cell cycle is distinguished by A) an active preparation for DNA synthesis. B) a doubling of chromosomes. C) an absence of preparation for DNA synthesis. D) the appearance of a metaphase plate. 8.Cell division, the climax of the cell cycle, consists of A) chromosome replication and separation. B) the breakup of the nucleus at the metaphase plate. C) mitosis or meiosis. D) the formation of a new karyotype. 9.Which of the following must occur before cell division begins? A) duplication of the nucleus B) DNA synthesis C) cytokinesis D) DNA segregation 10.Which of the following is true of the chromosomes in a homologous pair? A) They both came from the organism’s mother. B) They both came from the organism’s father. C) One chromosome came from each of the organism’s parents. D) Neither chromosome came from the organism’s parents. 11.When examining the rapidly dividing cells of the onion root tip, you see a cell whose chromosomes are visible and are arranged in approximately the same size and shape as the nucleus. What stage of mitosis is this cell in? A) metaphase B) prophase C) anaphase D) telophase 12.When examining the rapidly dividing cells of a fish embryo, you notice a cell that seems to contain two nuclei. The middle of the cell is pinched inward. This cell must be in _____ of mitosis. A) prophase B) telophase C) metaphase D) anaphase 13.Plants perform cytokinesis differently than animals because A) plant cytokinesis takes place during interphase but animal cytokinesis takes place in cell division. B) plant chromosomes are more difficult to separate than animal chromosomes. C) the rigid cell wall of the plant cell prevents the plasma membrane from pinching inward like it does in animal cells. D) the centrosomes of plants do not replicate prior to cell division. 14.At the completion of mitosis, the nucleus of a human somatic cell has ___ chromosomes. A) 23 B) 46 C) 92 D) 184 15.The successful union of one male and one female gamete forms a new single cell known as a A) histone. B) zygote. C) vesicle. D) T cell. 16.After a single cell undergoes meiosis, how many new cells will be produced? A) 2 B) 4 C) 12 D) 16 17.Only meiosis could lead to the production of new A) skin cells. B) brain cells. C) sperm cells. D) liver cells. 18.If a plant has a karyotype of 18 chromosomes, how many chromosomes would be present in each of its gametes? A) 36 B) 18 C) 9 D) 6 19.Adult stem cells differ from embryonic stem cells in that A) embryonic stem cells are found throughout the body of the fetus, but adult stems cells are found only in adults. B) adult stem cells are easier to obtain than embryonic stem cells. C) adult stem cells can differentiate into fewer types of cells than embryonic stem cells. D) embryonic stem cells do not require differentiation signals like adult stem cells do. 20.Induced pluripotent stem cells (iPS) differ from embryonic stem cells (hES) because A) iPS cells are made with viruses rather than being harvested from an embryo B) iPS cells exhibit the same properties as hES cells but are made from adult somatic cells rather than embryonic cells. C) hES cells have the same DNA as their recipient and are less likely to be rejected than iPS cells. D) hES cells are more highly differentiated than iPS cells.

• Answer:

  Sorry my last biology class was in 1975. But if you bring me the book(Little Rock AR) I'll read the chapter and answer the questions for you.
