BIOLOGY Final Semester 1 Exam

Colleen conducts an experiment to see if eating an apple before a test improves scores. What is the independent variable?

• the (eating of) apple
• the test score before the apple
• test score after the apple
• test score without eating an apple

Ethan conducts an experiment to see if using a cell phone before sleeping has an impact on the amount of hours slept. What is the dependent variable?

• cell phone light
• hours slept
• type of cell phone
• location of sleep

if you wanted to make a reaction in your body speed up, you should add a(n)

• strong acid
• enzyme (catalyst)
• strong base
• glycerol 

which two things fit together like a lock and key

• enzyme and substrate
• glucose and fatty acid
• cell membrane and nucleus
• endocytosis and exocytosis

match the correct biological molecule and its monomer (only 1 is correctly paired)

• lipids - glycerol + 3 fatty acids
• nucleic acids - glucose
• proteins - monosaccharides
• carbohydrates - amino acids

match the biological molecule with its correct function

• nucleic acid - stores genetic code (DNA)
• carbohydrates - long term energy storage
• lipids - short term energy storage
• proteins- store genetic code (DNA)
