Explain the difference between kinetic and potential energy
Kinetic energy is energy in action and potential energy is energy that is stored (but can become kinetic)
15
What subatomic particles are found in the nucleus?
protons and neutrons
15
What is the atomic number?
number of protons in nucleus
15
What is the mass number?
total number of protons and neutrons
15
What is the difference between molecules and compounds?
A molecule is two or more of the SAME TYPE of atom are bonded together, a compound is two or more of DIFFERENT TYPES of atoms bonded together
15
Explain the difference between ionic bonds and covalent bonds.
Covalent bonds share electrons to form a bond, ionic bonds gain/lose electrons between the other atom
15
Explain a dipole.
Has two different charges (h2o is an example because hydrogen is negative and oxygen is positive)
15
What type of reaction is forming a larger, more complex molecule?
synthesis, anabolic
15
What type of reaction is breaking down complex molecules to form simpler ones?
decomposition, catabolic
15
What type of reaction includes both synthesis and decomposition?
exchange (or displacement)
15
Describe the octet rule
Atoms desire 8 electrons in their valence shell and will gain/lose/share electrons with other atoms to become stable
15
A patient's blood is drawn then placed in a vile in a centrifuge. After it gets mixed around, the plasma, platelets, white blood cells, and red blood cells will settle out. What type of mixture is blood?
suspension
15
What type of mixture has particles that do not dissolve but do not settle out?
colloid
15
Where can the electrons of an atom be found?
in the electron shell/cloud
15
Describe the difference between anatomy and physiology
anatomy is the structure, physiology is the function
