Introduction
anything that takes up space and has mass
matter
water is the universal -_____ because it can dissolve most substances
solvent
water is made up of what atoms
2 hydrogens and 1 oxygen
which macromolecule is hydrophobic
lipid
monomers of carbohydrates
simple sugars (monosaccharides)
atom
water is a ______ molecule because the electrons are not shared equally between the atoms
polar
things that do NOT dissolve in water are considered hydro_________
which macromolecule main function is quick energy
macromolecule that creates enzymes, hormones, does transport, creates channels and carriers, creates antibodies, and many more functions
proteins
determine the charges of each (must get all 3)
protons, neutrons, electrons
protons- positive
neutrons- neutral
electrons- negative
ice is ______ dense than water, therefore it will float on top of liquid water
less
why is ice floating on top of water important factor for life?
life can still exist underneath the ice, where water is still flowing
which macromolecule stores genetic information
nucleic acids
monomer of proteins
type of bond where electrons are SHARED between atoms
covalent
waters temperature does not fluctuate easiliy, why is this important?
prevents water temperatures from getting too ho
or
moderates earths climates because trapped heat is released at night when air is cooler
the bond between adjacent water molecules
hydrogen
macromolecule that forms the outer barrier of the cell
lipids (phospholipids)
macromolecule that is never used as an energy source
nucleic acids
type of bond where electrons are transferred from one atom to another
ionic
properties of water that allow water to move from the roots of a plant to the top leaves.
cohesion and adhesion
in the penny lab, why did the soap water not form as many drops as the tap water
soap breaks the hydrogen bonds
what is the structure of a phosopholipd
hydrophobic tails, hydrophilic heads
monomer of nucleic acids
nucleotides
