Question #3 Growth and repair of the body cells happen because of ____________. In organisms that reproduce sexually, gametes are produced by _____________. a. Mitosis; meiosis b.Meiosis; mitosis c. Mitosis; conjugation d.Meiosis; gametogenesis
Question #4 Before mitosis can start, what must happen first? a. chromosome replication, formation of the cell plate, growth b. growth of cytoplasm, duplication of cellular organelles, chromosome replication, formation of the cleavage furrow c. growth, replication of chromosomes, duplication of cellular contents, chromosomal alignment in the middle of the cell d. growth and duplication of cell organelles, chromosome replication, growth and repair of chromosomal errors
