Sympathetic nervous system After playing a strenous tennis match, a player
experiences increased heart rate, rapid breathing, and
dilated pupils. Which branch of the nervous system is
responsible for these responses?
Autonomic nervous system
Central nervous system
Sympathetic nervous system
Parasympathetic nervous system

too weak?
Rectus femoris and vastus medialis
Pectoralis major and subclavius
Gastronemius and soleus

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
Fewer cones and a greater dusk/dawn
concentration of rods to
collect the minimal light An absence of cones since nocturnal mammals only need rods
for night vision.
to see black/white at night
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.

, Diffusion 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
Active transport
Osmosis
Cellular respiration
Lymphocytes As part of the human immune response, which of these
cells are responsible for producing antibodies?
Macrophages
Suppressor cells
Helper cells
Lymphocytes
Atlanto-occipital joint When a person nods their head yes/no, which joint allows for
that movement?
Coxal join
Atlanto-occipital joint
Temporomandibular joint
Glenohumeral joint
What structure within the area
labeled as B contains the sensory
receptors for dynamic equilibrium?
