Which process is most closely associated with the regulation of water loss from the leaves of trees?
a) digestion of water within the cytoplasm in the leaf cells of the trees
b) synthesis of protein by the chloroplasts in the leaf cells of the trees
c) movement of water through leaf openings controlled by the guard cells
d) absorption of nitrogen through leaf openings controlled by the guard cells

In the leaf of a plant, guard cells help to
a) destroy atmospheric pollutants when they enter the plant
b) regulate oxygen and carbon dioxide levels
c) transport excess glucose to the roots
d) block harmful ultraviolet rays that can disrupt chlorophyll production

The primary function of stomata is to
a) convert sunlight into usable energy
b) minimize water loss
c) facilitate gas exchange for photosynthesis
d) signal guard cells to open or close

Which statement best describes how these substances interact in photosynthesis?
a) glucose and oxygen combine to produce carbon dioxide and water
b) carbon dioxide and water combine to produce glucose and oxygen
c) oxygen and carbon dioxide combine to produce glucose and water
d) glucose and carbon dioxide combine to produce oxygen and water

Antibiotics are substances used to help fight an infection of Streptococcus, a bacterium that causes strep throat. Overuse of these antibiotics can
a) prevent future infections by these pathogens
b) cause a decrease in the production of enzymes
c) allow organic molecules to be synthesized
d) select for resistant organisms

The respiratory system includes a layer of cells in the air passages that clean the air before it gets to the lungs. This layer of cells is best classified as
a) organelle
b) a tissue
c) an organ
d) an organ system

A similarity between humans and many other multicellular animals is that they
a) occupy the same niche in most food webs
b) are composed of organ systems
c) have the same DNA sequences
d) carry out autotrophic nutrition

Which sequence best represents increasing complexity?
a) tissues → cells → organelles → organs
b) cells → organelles → organs → organism
c) organelles → cells → tissues → organs
d) organism → cells → tissues → organelles

One effect of uncontrolled diabetes is that the blood might develop an acidic pH. As a result, cells may not be able to regulate their internal pH. Within these cells, this could cause a disruption of the function of biological catalysts known as
a) enzymes
b) antibodies
c) antigens
d) toxins

A small lizard spends the morning hours lying in the sunlight until its body temperature rises. Later on in the day, the lizard rests in a shady area until its body temperature cools. This type of behavior is important to
a) maintain homeostasis
b) detect variations
c) attract mates
d) obtain nutrients

Medical professionals are concerned with the increase in the number of bacterial species that are resistant to antibiotics. Once resistance appears in a bacterial population, it spreads rapidly. This is most likely because
a) populations of resistant bacteria are small
b) exposure to antibiotics increases the rate of reproduction in bacteria
c) resistant bacteria are small when compared to non-resistant bacteria
d) resistant bacteria survive in greater numbers and pass the trait to their offspring

If the same antibiotic is used too many times, it can become less effective against a certain type of bacteria. This observation is best explained by the
a) presence of pathogens in antibiotics
b) production of antibiotics by white blood cells
c) replication of viruses that attack bacteria
d) survival and reproduction of unaffected bacteria
