- 18-22
- 3-6
- 36-38
- 42-46
36-38

- 4
- 8
2
What are two types of fermentation ?
Lactic acid and alcoholic
Besides ATP, what is the other product of the electron transport chain?
- H2O
- NADH

H20
What is the correct order of the four phases of the M phase in mitosis ?
PMAT
___ is the longest phase of meiosis, typically consuming 90% of the time of the two divisions.
- Telophase II
- Prophase I
- Prophase II
- Metaphase I
Prophase 1
Name the Mitosis Phase - The DNA lines up along the central axis and the centrioles send out specialized tubules that connects to the DNA. The DNA has now condenses into chromosomes. Two strands of chromosome are connected at the center with something called a centromere.
Metaphase
Plants and some algae have both haploid and diploid multicellular stages. The multicellular diploid stage is the __ .
- haploid gamete cell
- zygote
- sporophyte
- gametophyte
Sporophyte
What is the name of the longest portion of the cell cycle?
- Metaphase
- Interphase
- Prophase
- Cytokinesis
Interphase
What type of cells are produced from meiosis?
- Chromosomal cells
- diploid cells
- Haploid cells
- Autosomal cells
Haploid cells
Prior to __ , each chromosomes makes an exactly duplicate of itself. The chromosomes then thicken and coil.
- G1 phase
- Mitosis
- S phase
- Prophase II
Mitosis
If an organism is found to have 42 chromosomes in their diploid somatic cells, how many chromosomes should be present in their haploid, gametes?
- 23
- 46
- 84
- 21
21
The following describes what stage of Mitosis:
Division is finishing up. The cell membrane closes in and splits the cell into two pieces. You have two separate cells each with half of the original DNA.
Telophase
Which of the following is NOT one of the three main parts of Interphase?
- G1, G2, G3, or S phase
G3 phase
The division of cytoplasm at the end of the mitotic phase is known as ___ .
- Telophase, Telokinesis, Cytokinesis, or Synthesis
Cytokinesis
How many chromosomes would a human liver cell have?
- 0,23,46,92
46
___ is the pairing of homologs to form a tetrad.
- Synapsis
- G0 phase
- Mitosis II
- Meiosis II
G0 phase
What is the end result of meiosis ( what type of cell are form) ?
- 2 haploid daughter cells
- 4 diploid daughter cells
- 4 haploid cells
- 2 diploid cells
2 haploid daughter cells
