1. What is the difference between a solid and a liquid?
- Solids have a definite shape and volume while liquids have a definite volume but no fixed
shape.
1. Which part of the respiratory system is responsible for regulating breathing rate and depth?
- Diaphragm
1. What is the difference between a monosaccharide and a disaccharide?
- Monosaccharides are simple sugars that cannot be further broken down into simpler sugars
while disaccharides are composed of two simple sugars.
1. Which of the following is the process by which DNA is copied into RNA?
