100
Organs are...

100
The first phase of mitosis is...
Prophase
200
Third step of Interphase
Gap 2
200
Mitosis divides a cell's nucleus into two genetically identical nuclei, each with its own single, full set of...
DNA
200
Programmed cell death
Apoptosis
200
As organ systems work together, they help an organism maintain...
Homeostasis
200
Tissues are...
Groups of cells that work together to perform a similar function
300
What happens during the stage synthesis?
DNA is copied.
300
What happens during the third phase of mitosis?
Anaphase Spindle fibers shorten making the sister chromatids seperate from each other and move towards the opposite sides of the cell.
300
Examples of Carcinogens
Tobacco smoke, viruses, air pollutants, ultraviolet radiation (sunlight)
300
List the following in order from smallest to biggest: Organ Cells Organ System Tissues
1. Cells 2. Tissues 3. Organs 4. Organ System
300
2 types of cancer treatments involve...
Radiation & chemotherapy
400
Errors in the Synthesis phase results in...
mutation.

What happens during cytokinesis?
It divides the cytoplasm between two daughter cells, each with an identical nucleus. The cells enter interphase and start the cycle again.
400
Difference between Malignant and Benign tumors.
Malignant: cells can break away from tumor Benign: the cells stay clumped together
400
Possible uses for stem cells.
-Treat patients with diseases -Research -Helps find cures
400
Another word for when cells can break away
Metastasize
500
Explain the difference between Gap 1 and Gap 2.
Gap 1: Cells grow, replicate organelles Gap 2: Additional growth
500
The phases of mitosis are...
1. Prophase 2. Metaphase 3. Anaphase 4. Telophase 5. Cytokinesis
500
Internal and external factors that regulate the cell cycle
Internal: -Kinases (enzyme that transfers a phosphate group from 1 molecule to another molecule) -Cyclins (group of proteins that are rapidly made and destroyed at certain points in the cell cycle) External: -physical/chemical signals -cell contact makes other cells stop dividing
500
What three different potentials do stem cells have? Explain each.
Totipotent: can grow into any other cell type Pluripotent: can grow into sny except totipotent stem cells Multipotent: can only grow into cells of a closely related cell family
500
What is the difference between a chomatin and a chromatid?
Chromatin: the loose combination of DNA and proteins Chromatid: One half of a duplicated chromosome
