11) How many chromosome will those daughter cells have?

12) Will the chromosomes/DNA in the daughter cells be identical to the original cell?

13) What process happens after mitosis in the cell cycle that divides the cytoplasm?

Mitosis and Meiosis

14) How many daughter cells will it produce?

15) How many chromosome will those daughter cells have?

16) Will the chromosomes/DNA in the daughter cells be identical to the original cell?

17) What happens during prophase 1 of meiosis that does not happen in mitosis?

Mitosis and Meiosis

18) Which process (meiosis or mitosis) allows for an organism to increase the number of body cells during development?

19) Name one advantage and one disadvantage to asexual reproduction.

20) Two gametes containing 20 chromosomes fuse during fertilization. How many chromosomes will the zygote contain?

21) What is the result of the fertilization of an egg? choose 1a. Restores the diploid number of chromosomesb. It gives offspring more chromosomes than the parentsc. It gives offspring fewer chromosomes than the parents.

Mitosis and Meiosis

22) After fertilization of an egg a zygote is formed. The zygote then undergoes mitosis to form a blastula then a gastrula. Then the cells begin to differentiate. What happens during differentiation?

23) A) What is the diploid number for humans?

B) What is the haploid number for humans?

Genetics and Heredity

24) Use a punnett square to predict the probability of the following parents having an offspring that is homozygous recessive. (must draw the punnetts)

B) Rr x Rr

C) rr x RR

D) Rr x rr

Genetics and Heredity

25)In a certain insect, round wings (R) is dominant to pointed wings (r). If two heterozygous insects are crossed what are the possible genotypes and their ratios?

26)In the same cross what are the possible phenotypes and their ratios?

27)What is this type of cross called?

Cell Transport

28) Name what type of transport each molecule below would require to move through the cell membrane. (choose from osmosis, diffusion, diffusion through ion channels, facilitated diffusion)a. Ionb. Waterc. Glucosed. Oxygen

29) Indicate which types of transport in your answer above require energy by placing the word active next to it. Write the word passive next to the ones that do not require energy.
