Science Assessment ~ Topics ~ Human Body Systems ~ Misconception BFM013

The carbohydrates, fats, and proteins from the food people eat are used by the body unchanged; they are not broken down into smaller molecules (AAAS Project 2061, n.d.).

Items that test for misconception BFM013 in this project (MEGA) and key idea (To build body structures, multicell…)
Item ID Number	Item Description	How Often the Misconception was Chosen
EB057001	Some of the molecules from milk a nursing infant drinks are changed into new molecules that become part of its body structures.	19%
EB060002	A friend who wants to keep her fingernails from breaking can eat proteins with all the necessary building blocks (amino acids) because her body can carry out chemical reactions to change proteins in her food to keratin.	13%
EB058001	The egg yolk gets smaller as a 5-day old chick grows inside an egg into a 10-day chick because some of the molecules from the yolk are broken down and assembled into new molecules that become part of the chick’s body.	12%
