How does a Natural Killer cell decide whether or not to kill a cell? And how does it kill a cell if it does decide to kill it?
Homework Answers
Natural killer cells is a part of innate immunity. Natural killer cells identifies that cells which doesn't have class MHC I molecule at surface. Natural killer cells has the ability to kill the tumour cells which losses MHC I molecules from surface. Natural killer cells destroy these cells. So, they decide to kill a cell if they don't have MHC I molecules at surface.
Natural killer cells has azurophilic granules at the surface which produces lymphotoxin that acts upon MHC I negative cells and destroy the target cells.

1.- How does an entrepreneur decide whether to supply a good? Will entrepreneurs continue to supply a good or service if consumers are unwilling to pay a price sufficient to cover the per-unit cost? 2. Incentives matter. Explain why businesses and entrepreneurs are more likely to voluntarily undertake the projects that consumers value highly relative to price and less likely to undertake the government-sponsored projects in which the per-unit cost of production is above the price consumers willingly pay.
