Mitosis - Answer️️ -The process by which cells divide, creating two identical daughter
cells.
Prophase - Answer️️ -The first phase of mitosis in which chromosomes condense and
become visible.
Anaphase - Answer️️ -The t...
Apoptosis - Answer✔️✔️-Programmed cell death that eliminates unnecessary cells during
development and removes unhealthy/damaged cells.
Explain the relationship between normal cell division and apoptosis. - Answer✔️✔️-In
normal cells, when there is DNA damage that the cell cannot fix, it undergoes apoptosis.
This prevents the damaged DNA from being passed on to daughter cells during mitosis.
Explain the relationship between cancerous cells and apoptosis. - Answer✔️✔️-In
cancerous cells, when there is DNA damage that the cell cannot fix, it does not undergo
apoptosis. Instead, it continues to divide even though it isn't supposed to, and the cells
overgrow the area and clump together, making more cells with damaged DNA.
What is the difference between normal skin tissue and melanoma? - Answer✔️✔️-Normal
skin tissue is well organized with boundaries between each layer. The cells are uniform
in size and shape. The tissues of melanoma do not have clear boundaries. The
melanocytes are clumped together in nests and migrating into other areas.
If you fall and scrape you knee, will you have a hole in your knee for the rest of your
life? Explain. - Answer✔️✔️-No. Inflammatory chemicals enter the blood supply, which tell
the body that there is an injury. The blood supply brings the necessary components to
the injury to heal it, like white blood cells and clotting and plasma proteins. Epithelial
cells undergo mitosis to fill in the wound.
How is the mitosis that takes place in a wound different from cancerous tumor cells? -
Answer✔️✔️-If there is a wound, epithelial cells undergo mitosis to fill in the wound. This
is a normal and necessary use of mitosis. The tumor cells divide on their own, not in
response to growth or injury.
