1.Identify the end products of protein digestion that made up the contents of test tube B after the two hours. 2.State what the result would be if the same enzyme that was added to test tube B was added to a test tube containing starch. Support your answer.

c, liquids evaporate, creating a gas

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
