What very famous molecule do ALL living things have in
common? - ANSWER-
DNA
What do biologists mean when they use the term
"HOMEOSTASIS"? - ANSWER-HOMEOSTASIS is maintaining a
constant regulated INTERNAL environment of all living things
What is the "standard" definition for EVOLUTION? -
ANSWER-Evolution is
GENETIC CHANGE in a ECOLOGICAL population
through time
What is a BIOGEOCHEMICAL CYCLE? How do they link
organisms together? -
ANSWER-A biogeochemical cycle is a predictable pattern in
which matter is
constantly being shuffled in the atmosphere
(RECYCLING)
,As these cycles
occur,
atoms Move in and out of organisms and link
them together
What is an ELEMENT? How is one specific element different
from any other element? - ANSWER-An element is a
UNIQUE type of atom with a specific number of protons
AND
a UNIQUE set of physical characteristics
Carefully DRAW the PLANETARY MODEL of a CARBON atom.
BE SURE TO LABEL all the important parts and indicate if any
of these parts
has a +/- charge - ANSWER-Planetary model of
carbon atom
(NOT the same as this picture, refer back
to quiz 3)
What are the 3 I's? - ANSWER--
Interact
-
Interconnected
-
Interdependent
,DNA's 2 uses are: - ANSWER-1. Recipes for
proteins
2. Genetic material = transfers recipes to
offspring
Characteristics of living things: - ANSWER-1. All living things
exhibit a unique,
complex & hierarchical
organization
2. All living things must acquire specific materials (atoms,
molecules) and
energy to maintain
organization
3. All living things must exhibit patterns of
development, growth, and
reproduction
4. All living things exhibit evolutionary and heredity "links" to
other organisms
5. All living things respond to environment
6. All living things are linked to other life through
biogeochemical cycles and
patterns of energy flow - they are part of the
biosphere
, What's the Big 5? - ANSWER-1. Water
2. Carbohydrates
3. Lipids
4. Protein
5. Nucleotides
HOW MANY covalent bonds does
Carbon/oxygen/nitrogen/hydrogen usually
form? - ANSWER--Carbon: 4
covalent bonds
-Oxygen: 2 covalent bonds
-Nitrogen: 3 covalent bonds
-Hydrogen: 1 covalent bond
What is an ION?
Carefully list ONE ion we have discussed in class - ANSWER--
An ion is a atom that has a positive (+) or negative (-) charge
-Na+
-Cl-
A COVALENT BOND is generally considered relatively
____________ (weak or strong), and is created by _______
(sharing electrons or attraction of opposite charges) -
ANSWER--Strong
