Which can be used to prevent initial entry of bacteria into the body

Inflammation.

Explanation:

The same reason you would die if your body temperature gets too high. Our bodies are meant to perform at an optimal temperature because the cells within our body perform cellular processes perfectly at that temperature. Same goes with bacteria. At high temperatures, proteins degrade and denature and fail to function. Your membrane transport proteins break apart: you can't get things in or out of your cells. You can no longer establish electron gradients for ATP synthesis: your body can no long provide itself with energy. Your ribosomes denature and fail to carry out protein synthesis: you cannot build new cells to replace the dying ones. You are dead.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
