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.
The answer is the number 2. Why? Because the cytoplasm is a fluid that sustains the cell shape. The mitochondria is a organelle, ribosomes are protiens and vacuoles are carriers/storage bins.
In a relative frequency distribution, the relative frequencies add up to the relative frequencies add up to 1.
- The frequency of a specific occurrence in a statistical experiment is compared to the overall frequency to determine its relative frequency. the proportion of favourable events that actually occur to all conceivable events; frequently used to assess probability. the percentage of a random variable's range that falls within a certain interval when it takes a specific value.
- Because the heights of relative frequency histograms can be translated into probabilities, they are significant. These probability histograms offer a graphical representation of a probability distribution that may be used to assess the probability that specific outcomes will materialise within a given population.
