When cells are not responding to normal controls over growth and division they form tissue mass known as?
When cells are not responding to normal controls over growth and division, they can form tissue masses known as tumors. Tumors can be either benign (not cancerous) or malignant (cancerous).
Is the percentage of cells in the resting stage is higher in cancerous cells than normal cells?
No, cancer cells are more active than normal cells. Cancer cells are always dividing at a faster rate than normal cells.
Which type of tissue would have a higher mitotic index normal tissue or cancerous tissue?
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
What are the key differences between normal tissue and cancerous tissue?
Normal tissue and cancerous tissue differ in several key ways. Normal tissue follows a controlled growth pattern, while cancerous tissue grows uncontrollably. Normal cells have specific functions and structures, while cancer cells often lack these specialized features. Additionally, normal tissue responds to signals that regulate growth and division, whereas cancerous tissue ignores these signals. Finally, normal tissue typically remains localized, while cancerous tissue can invade surrounding tissues and spread to other parts of the body.
What goes wrong with a normal cell when it becomes cancerous?
A normal cell turns cancerous when there is damage between a few of the genes that are in control of cell growth. These cells will eventually invade the blood supply and kill the host.
Why the cells depicted in line A are most likely cancerous?
The cells in line A are likely cancerous because they appear crowded, irregularly shaped, have enlarged nuclei, and are not organized in a uniform manner as normal cells. These characteristics suggest uncontrolled growth and division typical of cancerous cells.
What are the key differences between cancerous cells and normal cells in terms of their growth and behavior?
Cancerous cells grow uncontrollably and can invade nearby tissues, while normal cells grow and divide in a regulated manner. Cancer cells can also spread to other parts of the body, a process called metastasis, which normal cells do not do. Additionally, cancer cells can evade the body's immune system and resist cell death signals, unlike normal cells.
How does cancerous cell growth differ from normal cell growth, and can you explain the key distinctions between the two processes?
Cancerous cell growth is different from normal cell growth because cancer cells divide uncontrollably and can invade surrounding tissues. Normal cell growth is tightly regulated and stops when the body doesn't need more cells. The key distinctions between the two processes are the uncontrolled division of cancer cells, their ability to spread to other parts of the body, and their resistance to signals that would normally stop cell growth.
Is radiation more harmful to normal cells than to cancerous cells?
Radiation can harm both normal and cancerous cells, but because cancerous cells are often more sensitive to radiation, they may be more likely to be damaged or killed by radiation therapy. Normal cells can repair themselves more effectively than cancerous cells, which helps protect them from the effects of radiation.
What is a mutation that forms an oncogene that changes normal cells into cancerous cells?
to a gene
Does the cell cycle become uncontrolled in cancer?
Yes
How does cancerous growth occur?
Well cancerous cell growth divides more rapidly, and skips parts in the process. Its cells go through interphase faster than normal cells. They can multiply faster than any cell. The processes are the following:ProphaseMetaphaseAnaphaseTelophaseInterphaseInterphase is the longest Process out of all the processes. :)I hope this helped you out!! Im a 10th grader so im sure theres more informatation to be learned! :D
