when complex plants are produced by cloning,which process is most directly involved?(1) mitotic cell division(2)meiotic cell division(3) gamete production(4)sperm cell fertilization
12: if a lobster loses a claw, it is capable of growing a new one.what process makes this possible?(1)meiosis (2)fertilization(3)sexual reproduction(4)mitosis
13: organisms that reproduce asexually usually do so by a form of cell division called (1)meiosis(2) mitosis (3)gamete formation (4)sperm formation
14 a normal boby cell of a fruit fly contains eight chromosomes.each normal gamete of this oganism contains(1)four chromosomes as a result of meiosis(2)four chromosomes as a result of mitosis(3)eight chromosomes as a result of meiosis(4)eight chromosomes as a result of mitosis
15 theprocess of mitotic cell division normally results in the production of(1)four cells with half the number of chromosomes as the parent(2)two cells with the same number of chromosomes as the parent (3) two cell with a replicated set of matched chromosomes
16 each of the two daughter (or offspring ) cells that result from the normal mitotic division of the original parent cell contains (1) the same unmber of chromosomes but different genes than the parent cell(2)the same number of chromosomes and genes identical to those of the parent cell (3)one half of the number of chromosomes but different genes than those of chromosomes but different genes than those of the parent cell (4) one half of the number of chromosomes and genesidentical to those of the parent cell

how many cells will finally be produced?
how many chromosomes will be in each cell?
sketch one of the final cells,showing its chromosomes.
