Which sequence represents structures organized from most complex to least complex?  

• (1) chloroplast → guard cell → leaf → oak tree 
•  (2) guard cell → chloroplast → leaf → oak tree 
• (3) oak tree → guard cell → leaf → chloroplast 
• (4) oak tree → leaf → guard cell → chloroplast

Autotrophs differ from heterotrophs in that only autotrophs     

• (1) require carbon dioxide for cellular respiration 
• (2) release oxygen as a product of cellular respiration 
• (3) synthesize nutrients using carbon dioxide and water 
• (4) break down sugars to assemble other molecules

In humans, the maintenance of a stable internal temperature is a direct result of  

•  (1) detection of and reaction to stimuli in the environment 
• (2) digestion of starches and absorption of protein from the internal environment 
•   (3) diffusion of water and excretion of glucose to the external environment 
• (4) transport of ATP and locomotion through the environment

The student observed the unicellular organism shown in the image, predicted that the contractile vacuole, which eliminates excess water, would contract fewer times in one minute in a solution that had a higher concentration of salt than that found in typical pond water. This prediction is most likely: 

• correct, because water would be moving out of the cell into the salt solution
• correct, because a high concentration of salt in the environment will force water into the cell, causing the contractile vacuole to pump
• incorrect, because salt would be entering the cell, and the contractile vacuole would have to pump it out 
•  incorrect, because the concentration of salt in the environment should not affect a cell 

. An amoeba, a one-celled organism, can move, ingest, and transport materials within the cell, because it has:  

• systems
• tissues
• organelles
• organs

An individual walks out of his air-conditioned (75°F) home into the hot outside environment (85°F). His ability to adjust to this changing environment involves a mechanism similar to:  

• glucose production in the pancreas 
• using ATP for the diffusion of water
• the digestion of carbohydrates by enzymes 
• the regulation of water loss by guard cells in plant leaves

The shape of a protein molecule directly determines its:  

• circulation throughout the body
•  roles in building water molecules 
•  functions inside and outside of cells 
• movements through the cytoplasm

In an experiment testing the effects of various brands of fertilizer on sunflower growth, the type of fertilizer would be

• the independent variable
• the dependent variable
• a controlled variable (aka- a constant)

In an experiment testing the effects of various brands of fertilizer on sunflower growth, the growth of the sunflower plant would be

• the independent variable
• the dependent variable
• a controlled variable (aka- a constant)
