What type of data describes descriptions rather than measurements
Qualitative
Describe an isotope
atoms of an element that differ in number of neutrons
triglycerides(oils/fats) being hydrolyzed
Saponification
A researcher observes several different species of living organisms and notes that they all exhibit cellular organization. From this, they conclude: 'All living organisms are composed of cells.' This is an example of
Inductive reasoning
Water exhibits high specific heat and high heat of vaporization primarily due to

The regular, repeating structures of a polypeptide—such as the α-helix and β-pleated sheet—are maintained by hydrogen bonding along the backbone. This represents which level of protein structure?
Secondary
Describe a law AND a theory
law: correlation between measured variables(think math expressions)
theory: offers an explanation of natural phenomena(explains the why)
Based on the rules of electron configuration, what is the maximum total electron capacity of the second energy shell (n = 2)?

Margarine is made by hydrogenating vegetable oils so that they take on the consistency of butter. Which of the following is the chemical basis for this change from a liquid to a solid?
Fats are changed from unsaturated to saturated, allowing them to solidify
