In the diagram, the area labeled 2 is part of which
layer of the eye?
Fibrous tunic Fibrous tunic
Sensory tunic
Reticular tunic

heart rate, rapid breathing, and dilated pupils. Which branch of the
nervous system is responsible for these responses?
Sympathetic nervous system Autonomic nervous system
Central nervous system
Sympathetic nervous system
Parasympathetic nervous system
Amnesia in humans is the loss of memory. Which of these parts of the brain
has been affected when someone is suffering from amnesia cuased by head
trauma?
Cerebral Cortex Medulla oblongata
Spinal Cord
Cerebellum
Cerebral Cortex
If a person cannot stand on tiptoes, which muscles may be too weak?
Rectus femoris and vastus medialis
Gastronemius and soleus Pectoralis major and subclavius
Gastronemius and soleus
Biceps femoris and semimembranosus

Is where most of the cell's chemical Carries hereditary traits
reactions take place Produces protein
Is where most of the cell's chemical reactions take place
Controls what moves in and out of the cell
, Most vertebrates have cone cells in their eyes, which distinguish colors in
daylight. The rods are more sensitive to light, but do not distinguish colors. If a
mamal is nocturnal, it has likely evolved to have...
As many cones as there are rods to capture the colors at dusk/dawn
An absence of cones since nocturnal mammals only need rods to see
Fewer cones and a greater black/white at night
concentration of rods to collect the
minimal light for night vision.
Fewer cones and a greater concentration of rods to collect the minimal light
for night vision.
More cones than rods to enable them to see the muted colors at night.
Whithin a living cell, the oxygen from a mixture of oxygen and carbon
dioxide is used up. This creates a concentration gradient across the cell
membrane that draws in oxygen across the cell membrane from the
outside to the inside of the cell. This process is known by which of these
terms?
Diffusion
Diffusion
Active transport
Osmosis
Cellular respiration
As part of the human immune response, which of these cells are responsible for
producing antibodies?
Lymphocytes Macrophages
Suppressor cells
Helper cells
Lymphocytes
When a person nods their head yes/no, which joint allows for that
movement?
Atlanto-occipital joint Coxal join
Atlanto-occipital joint
Temporomandibular joint
Glenohumeral joint
What structure within the area labeled as B
contains the sensory receptors for dynamic
equilibrium?
Crista ampullaris Macula sacculi
Spiral organ
Crista ampullaris
Macula utriculi
, If a person has a lateral curvature of the spine, which anatomical structure is
affected?
Vertebral column Thoracic cage
Pelvic girdle
Vertebral column
Pectoral girdle
Charles Darwin's theory of evolution suggests that the reason for the
various differences between species is a result of..
Natural selection The use or disuse of body structures
Exposure to mutagenic agents
Natural selection
Acquired characteristics
Which of these structures carries sperm cells from the testes to the lower
part of the abdomen?
Vas deferens Urethra
Seminiferous tubules
Vas deferens
Epididymis
Buffer region The titration curve shows a weak acid strong base.
What does the region in Box B represent?
(the region of the curve where pH
changes little with each addition of Equivalence point
a compound such as NaOH is the
Excess acid region
buffer region, a buffer resists
changes in pH. The excess acid Buffer region
region is relevant to a titration of a Excess base region
weak base strong acid titration.)
The vertical columns on the periodic chart are known as...
Periods
Groups Ions

Metalloids
Anaerobic respiration occurs in muscle tissue when it cannot get sufficient
oxygen to function aerobically. Which of these conditions is most likely to
directly result from this?
Cramps Cramps
Swelling
Necrosis
Bleeding
