hierarchic organizational system - 🧠 ANSWER ✔✔kingdom, phylum, class,
order, family, genius, species
steps to an experiment - 🧠 ANSWER ✔✔1. observation
2. hypothesis
3. experiment
,4. conclusion
observation - 🧠 ANSWER ✔✔data is observed and recorded/ previous data
is studied
hypothesis - 🧠 ANSWER ✔✔a statement or explanation of certain events or
happenings
experiment - 🧠 ANSWER ✔✔repeatable procedure of gathering data to
support or refute the hypothesis
conclusion - 🧠 ANSWER ✔✔where the data and its significance are fully
explained
aqueous - 🧠 ANSWER ✔✔water based
water molecule consists of - 🧠 ANSWER ✔✔two hydrogen atoms covalently
bonded to one oxygen atom
most significant aspect of water is - 🧠 ANSWER ✔✔the polarity of its bonds
that allows for hydrogen bonding between molecules
specific heat - 🧠 ANSWER ✔✔the amount of heat necessary to raise the
temperature of 1 gram of that molecule 1 degree celsius
, water has high specific heat due to - 🧠 ANSWER ✔✔the extent of hydrogen
bonding between water molecules, which allows waters to resist shifts in
temperature (ability of oceans or large bodies of water to stabilize climates)
cohesion - 🧠 ANSWER ✔✔the ability of a molecule to stay bonded or
attracted to another molecule of the same substance (water running
together on a newly waxed car)
adhesion - 🧠 ANSWER ✔✔the ability of water to bond to or attract other
molecules or substances (when water is sprayed onto the wall, some of it
sticks to the wall)
when water freezes it forms - 🧠 ANSWER ✔✔lattice crystals; causing the
molecules to spread apart, resulting in the phenomenon of ice floating
polarity of water allows it to act as an - 🧠 ANSWER ✔✔versatile solvent
(used to dissolve a number of different solvents)
carbohydrates - 🧠 ANSWER ✔✔longs chains, or polymers of sugar
-used for storage, structure, and energy
-the backbone of important molecules such as DNA and RNA
