BIOLOGY 2e GOOD SUMMARY FOR
EXAM REVISION
organization of life
molecular, cellular, tissue, organ, organ system, organism,
population, community, ecosystem, biosphere
scientific method
The process that starts with an observation that starts a
question, which then becomes a testable hypothesis. A
test is done with the hypothesis using recorded data, and
if the hypothesis is rejected, then either the hypothesis
gets changed or the procedures need to be redone.
properties of life
reproduction, growth and development, homeostasis,
energy processing, response to stimuli, regulation, and
order
properties of water
adhesion and cohesion which create surface tension and
capillary action
adhesion
the property of water sticking to surfaces
cohesion
the property of water sticking to more water
surface tension
comes from the hydrogen bonds of the polar water
molecule
capillary action
allows water to be dragged or pulled along
, acidic substance
a substance with a pH below 7, like vinegar
basic substance
a substance with a pH over 7, like baking soda
neutral pH
a substance with a pH of 7, like water
biomolecules
carbohydrates, lipids, proteins, nucleic acids; all made
from carbon
macromolecules
a large molecule created from dehydration synthesis
dehydration synthesis
the process of joining molecules by removing water
hydrolysis
the process of breaking down molecules by adding water
carbohydrates
a molecule that always has the chemical ratio of C₁H₂O₁
that are made of monosaccharides like glucose
lipids
a nonpolar molecule that are made of glycerol and fatty
acids
monosaccharides
a simple sugar molecule, like glucose
disaccharides
a sugar made of two monosaccharides, like sucrose
polysaccharides
a sugar made of multiple monosaccharides, like glycogen
glycerol
a molecule with 3 carbons that forms a fatty acid chain,
with the term Triglyceride
phospholipids
