In order to enter cells and be useful to the body, starch must be
absorbed through the skin
broken down into fats and water
digested into simple sugars
converted to carbon dioxide and ATP

an antibody
an antibiotic
a hormone
a starch
Which statement most accurately describes human skeletal muscle tissue?

It is voluntary and lacks striations.
Which disorder is defined as an inflammation of the joints?
gout
polio
meningitis
arthritis

ducts of the pancreas
cells of the esophagus
villi of the small intestine
muscular folds of the gallbladder
Which process is illustrated in the diagrams below?
circulation
absorption
peristalsis
ingestion
Base your answer on the diagram of the human heart and on your knowledge of biology.
Which sequence represents normal blood flow between the two sides of the heart?
A - F - D - C - B
B - G - H - I - C

D - E - I - H - G
Which type of vessel normally contains valves that prevent the backward flow of materials?
artery
arteriole
capillary
vein
Cells of the immune system are able to respond to the presence of invading organisms because they recognize the
antigens present on the invaders
antibodies present in invading pathogens
DNA pattern in the nuclei of viruses
antibiotics released from microbes
An activity that occurs in the human body is shown. This activity helps to
provide protection against pathogens
produce antibiotics to control disease
eliminate harmful gene alterations
regulate production of ATP by the cell
Which sequence correctly indicates the branching pattern of the human respiratory system?

trachea - bronchioles - bronchi - alveoli
alveoli - trachea - bronchioles - bronchi
alveoli - bronchioles - trachea - bronchi
In humans, the organ that most directly regulates the concentration of water in the blood is the
heart
liver
pancreas
kidney
When leg muscles respond to a stimulus by moving the foot, the response depends most directly on the functioning of
bronchioles
nephrons
capillaries
neurons
Regulation of heart rate is most closely associated with the
cerebrum
cerebellum
somatic nervous system
autonomic nervous system
The diagram shows the interaction between blood sugar levels and pancreatic activity. This process is an example of
a feedback mechanism maintaining homeostasis
an immune system responding to prevent disease
the digestion of sugar by insulin
the hormonal regulation of gamete production
An organism that reproduces asexually will have offspring that have
the same genetic information as both of its parents
different genetic information from either of its parents
the same genes as its parent
different genes from its parent

estrogen and testosterone
estrogen and progesterone
progesterone and insulin
progesterone and testosterone
