39
What is Mitosis?
- Cell makes an exact cory of itself through cell division. - Results in two genetically identical diplod cells.

41
Where is DNA contained?
In chromosomes.
42
When do chromosomes wrap into sister chromatids?
Exclusively during cell division.
43
What is a Genome?
An organism's complete set of DNA including all its genes.
44
What are histones?
Proteins which DNA molecules wrap around within chromatin. Together with DNA histones form a nuclesome.
45
How many chromosomes do Humans normally have?
46
46
What are the two main phases of a cell's life cycle?
1. Interphase 2. Mitotic phase
47
What are the five phases of Mitosis?

48
Which phase of Mitosis is this?
Prophase
49
Which phase of mitosis is this?
Metaphase
50
Which phase of mitosis is this?
Anaphase
51
Which phase of mitosis is this?
Telophase
52
Which phase of mitosis is this?
Cytokinesis
53
What is diffusion?
The movement of particles from an area of higher concentration to an area of lower concentration.
54
What is osmosis?
The diffusion of water across a semipermeable membrane.
55
Which solution is Isotonic, which is Hypertonic and which is Hypotonic?
56
What is tissue?
A mass of similar cells which form discrete regions of organs and perform specific functions.
57
What are the four types of tissue in the human body?
- Epithelial - Connective - Muscle - Nervous
58
What are five funtions of the Epithelial tissue?
- Protects deeper tissues from injury and infection - Senses stimuli - Absorbs chemicals, including nutrients. - Produces and releases chemical secretions. - Excretes waste.
59
What is the structure of epithelial tissue?
- Apical surface - Basal surface - Basement membrane
60
What is an apical surface?
The surface of an epithelial cell that faces an open area.
61
What is a basal surface?
The surface of an epithelial cell that faces the basement membrane.
62
What is a basement membrane?
The layer below the epithelium which anchors it to connective tissue.
63
Which type of epithelial tissue is this?
64
Which type of epithelial tissue is this?
65
Which type of epithelial tissue is this?
66
