What characteristics of water molecules contributes the most to the unique properties of
water? - ✔️✔️(Polar covalent bonds resulting in hydrogen bonding ???) (emergent
properties ???)
What are the steps of the scientific method? - ✔️✔️Step 1.) exploration and
observation Step 2.) hypothesis Step 3.) test or experiment Step 4.) evaluate results (
DO NOT use the word "prove." A hypothesis is either supported or rejected
What is the difference between polar and nonpolar covalent bonds? - ✔️✔️The number
of electrons being shared
What is taxonomy? - ✔️✔️Branch of biology that names and classifies species
How many domains of life are there? What are their names? - ✔️✔️Three; domain
bacteria, domain archaea, and domain eukarya
Which domain(s) are prokaryotic? - ✔️✔️Bacteria and archaea
Which domain is eukaryotic? - ✔️✔️Eukarya (and plantae, animelia, fungi)
What does eukaryotic mean? - ✔️✔️Has a nucleus (membrane enclosed)
What does prokaryotic mean? - ✔️✔️Has no nucleus or organelles
What are the additional eukaryotic kingdoms? - ✔️✔️Kingdom plantae, kingdom
animalia, kingdom fungi
Which eukaryote is not a kingdom, but a category instead? - ✔️✔️Protist
How do you write a scientific name? - ✔️✔️Capitalize the genus name and lowercase
species. Italicize if typing but underline if writing.

What is the maximum number of electrons each shell can have? - ✔️✔️
Which covalent bond shares electrons equally? - ✔️✔️Nonpolar
Which covalent bond DOES NOT share electrons equally? - ✔️✔️Polar
What is the mass number of an atom? - ✔️✔️The number of protons and neutrons in
the nucleus
What is the atomic number of an atom? - ✔️✔️The number of protons in an atom
What is a hydrogen bond? - ✔️✔️noncovalent attraction between a hydrogen atom and
an electronegative atom
What is electronegativity? - ✔️✔️Attraction of a particular atom for the electrons of a
covalent bonds (WHAT ELSE? EASIER?)
