In the pancreas, lipase converts fat to:

64% Answer Correctly

simple sugars

amino acids

glycerol and fatty acids

complex carbohydrates
Solution

The acids produced by the pancreas contain several enzymes that aid in digestion.  Lipase converts fat to glycerol and fatty acids. Pancreatic amylase breaks down complex carbohydrates into simple sugars. Trypsin converts polypeptides (the building blocks of protein) into amino acids.

61% Answer Correctly

diffusion

conduction

convection

radiation
Solution

Convection is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. Examples of heat transfer by convection include water coming to a boil on a stove, ice melting, and steam from a cup of coffee. 

5

Earth's history is divided into time periods, which of these is the longest time period? 

67% Answer Correctly

era

epoch

eon

age
Solution

The Earth is approximately 4.6 billion years old and its history is divided into time periods based on the events that took place and the forms of life that were dominant during those periods. The largest graduation of time is the eon and each eon is subdivided into eras, eras into periods, periods into epochs, and epochs into ages.
