Chapter 10 Biology Test
Interphase
Normal cells of the body spend most of their time in which phase of the cell cycle
Mutated
All of these items increase the likelihood of cells becoming __________ which means that cells may not repair and follow a proper cell division cycle.
Decreases
As a cells size increases, what happens to the surface area to volume ratio
Quickly
At what speed do cancer cells divide
Interphase
Cancer cells spent less time and what phase
Cell division
Cancer is when what cell process is uncontrolled
A tumor or cancer cells have spread from the original source
Define what happens if the body goes through metastasis
Faster
Do cancer cells grow faster or slower than normal cells
Yes
Do cells have the ability to start growing again after they stopped
No
Do muscle and nerve cells divide once they are developed
Yes
Do the skin, digestive tract, and bone marrow grow and divide
The cell grows and synthesizes new proteins and organelles
Explain what happens in the G1 phase
prepares for mitosis
Explain what happens in the G2 phase
Starts the process of cell division
Explain what happens in the M-phase
Where chromosomes are copied
Explain what happens in the S phase
They perform a biopsy
How do doctors determine if a tumor is cancerous
Chemotherapy kills normal cells
How does the body lose energy due to cancer
Carcinogens, genetics, virus, radiation
List 4 possible causes of cancer
Prophase
Longest period of mitosis
Interphase
Longest period of the cell cycle
False
True or false: Cancer cells stay in one place and cannot break away
True
True or false: cancer cells can grip and grab onto other cells and tissue
Surgery, chemotherapy, and radiation
What are 3 treatments for cancer
G1, S, and G2
What are the 3 states in interphase (in order)
Prophase, metaphase, anaphase, and telophase
What are the 4 phases in mitosis (in order)
To direct cells to speed up or slow down cell growth and division
What are the external regulators job
To proceed only when certain processes have happened inside the cell
What are the internal regulators job
Benign and malignant
What are the two types of tumors called
Cancer
What disease does uncontrolled cell division lead to
Cytokinesis
What divides the cytoplasm
Mitosis
What divides the nucleus
Halts cell cycle until all chromosomes have been properly replicated
What does the gene p53 do
The cell dies from either starving to death or by becoming toxic from its own wastes
What happens if a cell gets too big and its nutrients and DNA aren't getting to where they need to be
Does not migrate to other parts of the body and does not harm other body parts
What is a benign tumor
Can migrate to other parts of the body, potentially causing cancer spread in the body
What is a malignant tumor
A cluster of cells going through the uncontrolled mitosis
What is a tumor
G2 phase
What is the shortest phase in interphase
Cyclin
What protein did scientists say they found to help regulate the cell cycle
Centrosomes
What region does the centrioles lie in
