21. must occur for plant or animal to grow and develop normally...: growth factor
14. occurs during interphase...: chromosomes and organelles are duplicated
22. when animal cells are grown in a petri dish, they typically stop dividing once they have formed a single unbroken layer on the bottom of the dish. This arrest of a division is called...: density-dependent inhibition
18. phase of mitosis where nuclear envelope re-forms and nucleoli reappears...: telophase
8. sister chromatids are...: replicated forms of a chromosome joined together by the centromere and separated during mitosis or meiosos II
12. process by which the cytoplasm of eukaryotic cells divide to produce 2 cells is called...: cytokinesis
6. not true: cell division...: cell division is the reproduction of cells by mitosis or meiosis- it ensures continuity of life and helps fertilized egg to develop
17. which does not occur during miotic anaphase...: during anaphase, chromatids of each chromosome have separated and the daughter chromosomes are moving to the poles of the cell
3. "like begets like" refers to....: applies only to asexual- exact genetic replicas (on one type of DNA)
1. creation of offspring carry genetic information by single parent...: asexual reproduction
5. Virchow's simple and profound principle stated officialy in 1858 was that...: all cells come from cells
4. with the exception of identical twins, siblings who have the same 2 biological parents are likely to look similar because they have...: offspring inherits a unique combination of genes
10. prior to mitosis, each chromosomes of a eukaryotic cell consists of a pair of identical structures...: sister chromatids
19. a feature of plant cell division that distinguishes it from animal cells is...: the formation of a new cell wall
13. If S phase is eliminated from the cell cycle, daughter cells would divide...: one chromosome; there wouldnt be sister chromatids
16. during which phase of mitosis do the chromosomes line up on a plane...: metaphase
11. eukaryotic cells spend most of the cell cycle in...: interphase
2. difference between sexual and asexual reproduction: asexual: only one parent dividing by budding or single cell division sexual: 2 parents with unique combinations of genes
7. not true: prokaryotic...: prokaryots produce by binary fission (divides in half- asexual)
