An organism takes materials from its environment and processes them for its use. This statement best describes the life function known as:

1.   ?    transport
2.   ?    excretion
3.   ?    nutrition
4.   ?    regulation

Which organisms are represented in the cartoon below?

1.   ?    coelenterates
2.   ?    annelids
3.   ?    arthropods
4.   ?    chordates

Living things contain units of structure and function that arise from preexisting units. This statement best describes the

1.   ?    cell theory
2.   ?    lock-and-key model of enzyme activity
3.   ?    concept of natural selection
4.   ?    heterotroph hypothesis

Which structures could most likely be observed in cells in the lower power field of a compound microscope?

1.   ?    cell walls and chloroplasts
2.   ?    ribosomes and endoplasmic reticula
3.   ?    lysosomes and genes
4.   ?    nucleotides and mitochondria

What would most likely happen if the ribosomes in a cell were not functioning?

1.   ?    The cell would undergo uncontrolled mitotic cell division.
2.   ?    The synthesis of enzymes would stop.
3.   ?    The cell would produce antibodies.
4.   ?    The rate of transport of glucose in the cytoplasm would increase.

Most of the chemical reactions occurring in a living cell depend on the presence of an inorganic compound known as

1.   ?    glycerol
2.   ?    glycogen
3.   ?    maltose
4.   ?    water

What is a major distinction between living and nonliving matter?

1.   ?    Living matter is unable to diffuse materials.
2.   ?    Living matter is able to control chemical activities with organic catalysts.
3.   ?    Living matter is able to create energy.
4.   ?    Living matter is unable to use energy for metabolic activities.

Which organism is correctly paired with its main adaptation for gas exhange?

1.   ?    amoeba - nucleus
2.   ?    earthworm - nephridia
3.   ?    grasshopper - tracheal tubes
4.   ?    human - skin
