NATURE OF SCIENCE
This type of data describes characteristics using words rather than numbers.
qualitative data
Anything that has mass and takes up space is called this.
matter
These are the four major types of biological macromolecules.
carbohydrates, lipids, proteins, and nucleic acids
A student tests a new fertilizer on 20 plants. Another group of 20 plants receives no fertilizer and is used for comparison. The group receiving no fertilizer is called the
control group
These six elements make up most of the molecules found in living organisms.
carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur
The smaller building blocks that are joined together to form many larger biological molecules are called these.
monomers
his is the variable that a scientist purposely changes during an experiment.
independent variable
A molecule with an uneven distribution of electrical charge, such as water, is described by this term.
polar
The four major macromolecules include carbohydrates, lipids, proteins, and these molecules, which store genetic information.
nucleic acids
This variable is measured or observed to determine the effect of the independent variable.
dependent variable
This property of water causes water molecules to stick to other water molecules.
cohesion
A bear stores large amounts of energy in its body before winter. Which macromolecule is primarily responsible for long-term energy storage?
lipids
These are the conditions that are kept the same throughout an experiment.
constants
In a cup of salt water, identify the solute, solvent, and solution.
A scientist discovers an unknown molecule. It contains many amino acids folded into a specific shape. The molecule can speed up a chemical reaction. Identify the macromolecule
