Biologists use ball-and-stick models to stuóy complex molecules by representing atoms with balls and bonds with sticks. DNA is
a biological molecule that contains millions of atoms. What is a limitation of using a ball-and-stick model for DNA?
Some kinds of atoms that are found in DNA must be left out of the models.
DNA has so many atoms that the size and cost of a model could be too great.
It is impossible to distinguish different kinds of atoms with models.
The chemical bonds between the atoms in DNA must be part of the models.

Astudent completed a lab report. which correctly describes the difference between the "question" and "hypothesis' sections of her report? "question states what she is asking, and "hypothesis" states the result of her experiment "question" states what she is asking, and "hypothesis" states what she thinks the answer to that question is in 'if. then because" format. "question" describes what she is trying to find out, and "hypothesis" states the procedures and methods of data collection. "question" describes what she is trying to find out, and "hypothesis" states any additional information or prior knowledge about the question
