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.

Aspirin and other nonsteroidal anti-inflammatory drugs (NSAID) inhibit inflammation by inhibiting an enzyme in the prostaglandin
lisov135 [29]

Answer: The enzyme is found in different types of cells.

Explanation:

The result that can be concluded is that this enzyme is found in different types of cells. This is the reason that the medicines like aspirin and other non-steroidal anti inflammatory drugs inhibit the prostaglandin pathway and other pathways too.

These medication acts on the enzymes and it will act in the cells where this enzyme will be present. Hence, the enzyme is acting in different types of cells.

That question, this incomplete. The full question is:

3. Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks. One tree is left outside in normal conditions. The heights of the trees are measured once a week. What are the dependent variables, independent and the controlled variable of this experiment?

Answer:

  • Independent variable: different humidity levels
  • Dependent variable: the heights of the trees
  • controlled variable: the types of trees

Explanation:

An independent variable is one that exerts an influence within the experiment and can be measured, acting on other elements to promote the observation of a result. As the experiment seeks to observe the influence of humidity on the height of the tree, we can say that humidity is the independent variable.

Dependent variable is that which is influenced by the independent variable to generate a result that can be observed, can also be measured. As the experiment wishes to analyze how the height of the trees was affected by the level of humidity, we can say that the height of the trees is the dependent variable.

Controlled variable is that which is present in the experiment in a constant and equal way, cannot be measured. This variable is the type of trees.

What type of evidence would you look for in a natural setting to indicate that there is competition taking placle among the plan
alexdok [17]

In a study, competition among plants are normal. Hence, all plants required a few basic elements like the light, water, nitrogen, or phosphorus, depending upon the species and the location. Evidence that can conclude that competition do really happen in plants is that some plants release toxins into the soil, in their dropped leaves which wipe out the competition for soil nutrients (such as weeds). And when it come an area with many trees in close proximity such as a forest, height is also indicative of competition for light.
