Answer:
The labeled drawing is attached; I just grabbed an image off of the internet. You can do this by hand by just copying what's in your textbook or other reference materials. Let me define five main parts:
- <u>Retina.</u> This is a thin layer of tissue on the back of the eye that receives the signals of light and transfers them to the brain so you can understand them as color and sight.
- <u>Cornea.</u> This is the front part, a reflective layer that "refracts" light. What this means is that light doesn't go directly through it, but its path is almost deflected a little.
- <u>Sclera.</u> This is the part that looks white from the front. It's a protein covering to your eye, and it's very close to the cornea.
- <u>Iris.</u> This is the actually colored part of your eye. If you have hazel or blue eyes, the iris is that portion of the eye. It allows differing amounts of light in.
- <u>Pupil.</u> This is the black part of the eye. It's a hole that looks black because of all the light coming through and being absorbed.
Cancer cells are cells that basically bypass any sort of regulatory processes in the cell cycle (and mitosis - the splitting of the cell). This leads to uncontrollable cell growth/duplication which hence leads to more and more cancerous cells. Cancer itself is so hard to cure for a couple of different reasons. If the cells are in the form of a benign tumor, that is a tumor that does not spread from its original infected tissue, it should be "easy" to remove with surgery. However, if it metastasizes, or spreads into surrounding tissues through the lymph or blood systems, then it becomes even harder to remove because of its far reach and complex structure. Also, cancer cells can be simply described as normal body cells that have gone rogue. That being said, things such as antibiotics, that are designed to get rid of foreign bodies, cannot get rid of cancerous cells without getting rid of most of your regular body cells as well simply because they cannot tell the difference.
Hope this helps :)
