Answer:
Explanation:
Well this the basic question arises in every mind who starts to think about the sky.
The sun light is white in colour. When white light passes through the earth's atmosphere the gases and dust particles present in it make the white light scatter in all directions. The white light is then divided into VIBGYOR. among these seven colours red has the maximum wavelength and blue color has the least. So, blue is scattered most compared to red and the sky looks blue.
<span>'With advances in technology, doctors and surgeons are no longer the only types of scientists helping to treat cancer patients. Investigate the role of a physicist, mechanical engineer, biomedical engineer, optician, or computation mathematician in developing new technologies for cancer treatment. Create a job description that describes the education, training, and role of that scientist in cancer research. Also discuss the criteria and constraints that scientist faces.'
Broseph, I'm going to say this straight up.
Biology is not my strong suit. But I will try to answer your question.
The scientist would need a masters medical degree, </span><span>Ph.D. and/or M.D. The scientist would be testing the reaction of different chemicals and scenarios on cancer cells. The scientist faces the criteria of trying to slow down or stop the cancer cells from multiplying, and a constraint he/she would face is the fact that cancer cells from different DNA reacts differently than each other, so the problem is that a cure would need to work on all DNA types.

Answer:
In the entire solar system, the environment of planet earth is unique due to the presence of the atmosphere.
It is responsible for providing carbon dioxide and oxygen which are essential for the presence of life on earth.
Secondly, it helps in keeping the earth warm through the greenhouse effect.
It prevents the entry of harmful radiations of the sun into the atmosphere.
Answer:
cleavage of MIC at the cell surface by a protease
Explanation:
The immune system refers to a complex network of cells and proteins that function to eliminate potentially tumorigenic cells on a daily basis. However, cancer cells show mechanisms in order to escape immune responses. MHC class I chain-related proteins A and B (MICA and MICB) are expressed in normal and tumorigenic cells where they act as ligands of the NKG2D receptor. The expression level of these proteins (MICA and MICB) is finely regulated by the activity of metalloproteinases (i.e., by protease-mediated cleavage), but this mechanism is altered in cancer cells. Recently, drug therapies that stimulate NKG2D mediated tumor destruction by reducing the cleavage of MICA and MICB from the surface of cancer cells have been developed.
