100
Name the three types of chemical bonds.
What are ionic bonds and IONIC BONDS, HYDROGEN BONDS and COVALENT BONDS?
100
Liquid water cohesiveness and ice floating is a result of.
What is HYDROGEN BONDING?
100
Because Lipids don't have polymers, this makes them;
A. Different or B. The Same (as other molecules.)
What is A. Different?
100
Define Hypothesis.
What is IF THEN BECAUSE? (a testable explanation for a set of observations based on the available data and guided inductive reasoning)
200
All atoms of an element have the same number of these.
What are PROTONS?
200
This is a weak type of chemical bond. It occurs when a partially positive hydrogen atom (participating in a polar covalent bond) is attracted to a partially negative atom (participating in a polar covalent bond)
What is a HYDROGEN BOND?
200
Water temperature is moderated by...
What is the breaking and forming of hydrogen bonds?
200
The two types of nucleic acids are..
What is DNA and RNA?
200
The three domains are...
What is DOMAIN BACTERIA, DOMAIN ARCHAEA, DOMAIN EUKARYA?
300
The center of an nucleus of an atom is made of these.
What are PROTONS and NEUTRONS?
300
Describe an ion.
What is an atom that has loss or gained an electron and still has charge?
300
True or False: Water has life supporting properties.
What is True?
300
Define Nucleic Acid.
What is a polymer consisting of many nucleotide monomers; servers as a blueprint for proteins and, through the actions of proteins, for all cellular structures and activities.
300
Define BIOLOGY
What is THE STUDY OF LIFE?
400
Describe and isotope.
An atom with different numbers of neutrons? (but always has the same number of protons)
400
Equal sharing between atoms creates...
What are NONpolar COVALENT BONDS?
400
True or False: A bathtub full of lukewarm water may hold more heat than a teakettle full of boiling water.
What is True?
400

What is a functional biological molecule consisting of one or more polypeptides folded into a specific three-dimensional structure?
400
You test your hypothesis in this step of the scientific method.
What is and EXPERIMENT?
500
The definition of an atom.
What is the smallest unit of matter that still retains the properties of an element?
500
Unequal sharing between atoms creates polar covalent bonds. An example of a polar covalent bond is this

500
Describe why ice floats in water.
Why are water molecules in ice are farther apart than in liquid water?

Define a Lipid.
What is an organic compound consisting mainly of carbon and hydrogen atoms linked by non-polar convalent bonds? (It's mostly hydrophohbic.) (Lipids include fats, phospholipids, and steroids and are insoluble in water.)

List the steps of the scientific method in chronological order.
What is; Data, Hypothesis, Experiment, Record and Study Data, Analysis, Conclusion? (And In. That. Order.)
