Question 5

eukaryote

Answer 5

more than one linear chomosome

Question 6

what must happen to a chromosome before cell division

Answer 6

it must be duplicated

Question 7

Answer 8

body cells
diploid
divide by mitosis
humans: 2n=46

Answer 10

2 of each type of chromosome

Question 11

haploid

Answer 11

1 of each type of chromosome

Question 12

mitosis phases

Answer 12

prophase –> metaphase –> anaphase –> telophase

Question 13

mitosis definition

Answer 13

continuous process with observable structural features

Question 14

mitosis processes

Answer 14

chromosomes become visible (prophase)
alignment at the equator (metaphase)
separation of sister chromatids (anaphase)
form two daughter cells (telophase and cytokinesis)

Question 15

what happens during cytokinesis

Answer 15

cytoplasm of cell divided

Question 16

animal cells during cytokinesis

Answer 16

cleavage furrow

Question 17

plant cells during cytokinesis

Answer 17

cell plate forms

Question 18

what happens during anaphase

Answer 18

chromosomes walked to poles by motor proteins
kinetochore microtubules shorten at ends as they depolymerize

bacterial cells divide by

Answer 19

binary fission
