The main difference between Maltose and Maltase is that the Maltose is a chemical compound, sugar that exists in wheat and Maltase is a enzyme. ... Maltase catalyzes the hydrolysis of maltose to the simple sugar glucose

The Greenhouse Effect

- The greenhouse effect is the warming of the earth's surface and the air above it caused by gases in the air that trap energy from the sun. The heat-trapping gases are known as greenhouse gases.

During the day, the sun's solar energy penetrates the earths atmosphere. The earths surface then gets warme up. At ight the earths surface cools down, releasing the heat back into the air. Some of the heat,however, gets trapped by the greenhouse gases in the atmosphere. That is what keeps our earth at an average temperature of 15 degrees Celsius.

However, the greenhouse effect is... (More)

Evaporation is used to separate a soluble solid, like salt, from a solvent. The solution is heated up until the liquid particles get enough energy to form a gas. The gas particles spread on into the room leaving the solid particles behind on the clock glass.

A titration is a method that is used to investigate reactions between substances. It can be used to investigate the neutralisation reaction between an acid and a base. Titrations use pipettes and burettes to measure volumes of liquids very accurately. A pipette is used to measure an exact volume of a base to be added to a conical flask. A burette is used to measure the volume of acid that is added in the base in the conical flask. An indicator is added to the conical flask. At the endpoint of the titration, the last drop of acid neutralises the... (More)
