A tracer is used to find and keep track of molecules and organisms. It is used to follow a particle molecule goes into your body, or to study how a perticular organ functions. They are also used in agriculture.

Well a tracer is something that is useed to keep trakc of and find molecules of and organisms. It is used to follow a particle molicule which goes into the body and shows how particular organs function.

Tracers are used to find/keep track of molecules and organisms. It follows a particle molecule that goes into your body. It studies how the organs function. They can be used in like farming too. They are used in lots of things.

a tracer finds and keeps track of molecules and organisms. It is used to follow a paticle molecule that goes into your body, or study how a peticular organ functions.

it keeps track of molecules and organisims. they also use it to follow a particle molcule goes into your body and they study it

a tracer is used to find and keep track of moecules and organisism. it follows particle molecules the go in your body. or it is used to study how a perticular organ function.

A tracer can be used to feep track of certain molecules oan organisms. It is used to trace a certain molecule in your body and it shows how your organs function.

Well so a tracer would probably have to be used to find and keep track if molucules and organisms. It is used to follow a particle molecule goes into your body. YEah thats pretty much all i got for today!!!

A tracer is used to find or keep track of molecules that are in an organism. Scientists can use this to follow where a particular molecule goes in your body. They can also use this to study how a particular organ functions.

A tracer is used to track and keep track of molecules, sometimes organsims too. It is sometimes used to follow a molecule that goes into your body also to study a certain organ and how it functions. They are also sometimes used in the area of agriculture. Thats pretty much all I know so enjoy the info.

A tracer is used to help find and help keep track of the molecules and organisms. Also it is used to keep track of the particle molecule that goes into your body and to study how a particular organ functions and is used for tracking stuff.

When a radioisotope is used to find or keep track of molecules in an organism, it is called a tracer.
Scientists can use tracers to follow where a particular molecule goes in your body or to study how a particular organ functions.

It is a radioisotope that is used to find or keep track of molecules in an organism. They are used in our bodies and for crops. Some are Carbon 11, Iodine 131, and Sodium 24. These are used in our bodies and are good tracers.

A tracer is used to find or keep track of molecules in an organism. It is traced through a biological, chemical, or physical system in order to study the system. It is also used to follow a molecule that goes into your body.
