6 Water is classified as an inorganic compound because it
1 does not contain carbon
2 does not contain nitrogen
3 contains hydrogen
4 contains oxygen
7 A student placed groups of 50 seeds in a variety of
temperatures ranging
from 0 to 50oC.
A difference in the rate of germination
observed in the groups at different temperatures
was most likely due to the effect
of temperature on
1 ammonia 3 enzymes
2 acids 4
cellulose
8 The series of diagrams below represents a process carried out
by a
unicellular organism.
This process is known as
1 autotrophic
nutrition 3 sporulation
2
replication
4 phagocytosis
9 Glucose molecules that are produced by green plants can be
1 converted into starch by dehydration
synthesis and stored in roots
2 converted into cellulose by hydrolysis and stored in leaves
3 used as catalysts for metabolic activity
4 used as a raw material for photosynthesis
10 Fungi, such as bread mold, use a method of digestion that
is
described as
1 chemical and intracellular
2 chemical and extracellular
3 mechanical and intracellular
4 mechanical and extracellular
11 In the diagram of the plasma membrane shown below, which structures
are indicated by letters A and B?
(1) A - proteins; B - lipids
(2) A - fats; B - carbohydrates
(3) A - cellulose; B - fats
(4) A - water; B - proteins
12 A chewing insect damages the vascular tissue of a plant stem. This
damage will most directly affect the
1 excretion of carbon dioxide by root cells
2 conduction of water and minerals between the roots and leaves
3 synthesis of auxins in the roots
4 diffusion of oxygen between root epidermal cells
