compound?
One that contains
Carbon and or
Hydrogen.
2. Name two activities
that would describe the
process of transport.
Walking, distributing
nutrients by means of
the circulatory system,
moving O2 throughout
the body.
3. Which process takes
simple materials and
chemically combines
them to make complex
materials?
Synthesis
4. What will happen if an
organism fails to
maintain homeostasis?
The organism may
become ill, or die.
5. Proteins are sources of
Amino acids
6. Undergoing an internal
and external balance is
known as
Homeostasis
7. Organisms are able to
survive because they
carry out
Metabolic activities
8. The cell organelle
involved with the
bonding of amino acids
is
Ribosome
9. Hemoglobin, insulin,
maltase, and albumin
are composed of chains
of amino acids. These
are examples of
Proteins
10. Glycogen and
glucose are included in
a group of organic
molecules called
Carbohydrates
11. Enzymes are proteins
that
Affect the rate of
chemical reactions.
12. All living things are
composed of the
elements
Carbon, hydrogen,
oxygen, and nitrogen.
13. The life process in
which a green plant
makes its own food is
called
Nutrition.
14. All organelles in a cell
work together to
perform
Metabolic processes.
15. Animal cells do not
contain
Chloroplasts
16. The level of body
organization from the
simplest to the most
complex is
Organelles-->Cells-->Tissues->Organs--> Organ Systems-> Organism
17. Certain hormones
can attach to the cell
membrane because of
specific
Receptor sites
18. Mitochondria are
found in cells that
require
Less energy
19. Any time we mention
the word Protein we look
for the following key words
in our answer
Amino acids, Ribosomes,
Enzymes, words ending in
“in” (trypsin, pepsin)
20. The following structure
found in the cell is
responsible for the
movement of materials
into and out of it.
Cell membrane
21. A small organ that
performs a special
function inside the cell is
called an
organelle
22. The following chemical
reaction is
called_______________.
Glucose+oxygen-->carbon dioxide+water+ATP
Cellular Respiration
23. Which structures carry
oxygenated blood?
Arteries (carry blood
away from the heart).
24. Cell receptors and
antibodies are similar
because
They are highly specific in
their actions.
25. How do guard cells of
a leaf help to maintain
homeostasis in a plant?
Guard cells allow
materials to pass into
and out of the leaf, ex.
Water and gases.
26. Pick two of the following
life processes and define
them and explain how
they interact.
Coordination, Excretion,
Digestion, Circulation,
Synthesis.
27. What best describes a
change that takes place
in the human body when
the heart rate increases as
a result of exercise?
More oxygen is delivered to
muscle cells.
