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.
When heat<span> is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The </span>motion<span> and spacing of the </span>particles<span> determines the state of matter of the substance. The end result of increased molecular </span>motion<span> is that the object expands and takes up more space.</span>
The answers, in order, are Commercial Fisherman, A technique for hunting, and if the sun is part of it, than it is false, if not, it is true... (I would go with True myself though)
I hope this helps!
<span>The most common type is simple columnar epithelial cells. These cells help the stomach resist degradation by the lumen during digestion. In addition, these cells secrete substances like mucous, HCl, and pepsinogen. All these secretions are necessary for proper digestion to take place.</span>
