Unit 5: Review february

The movement of molecules from side A to side B is an example of the process of

• active transport

• chromatography

• cellular respiration

• diffusion

molecules small enough to pass through the pores of cell membranes can passively leave the digestive system and enter the blood through what process?

• diffusion
• active transport
• photosynthesis
• cellular respiration

Which sequence represents structures organized from MOST complex to LEAST complex?

• (1) cells → organ systems → organelles → organisms

• (2) organelles → cells → tissues → organs

• (3) tissues → organs → cells → organ systems

• (4) organs → tissues → cells → organelles

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

An individual eats a hamburger. Which two systems must interact to transfer the nutrients in the hamburger to human muscle tissue?  

• circulatory and respiratory
• digestive and circulatory
• digestive and immune
•  respiratory and excretory

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar
• CO₂ + sugar + H₂O --> O₂ + light
• _O2 + light + H₂O --> CO₂ + Sugar
• CO₂ + O₂ + H₂O --> Light+ Sugar

Which organisms perform Photosynthesis?

• Only Autotrophs
• Only Heterotrophs
• Autotrophs and Heterotrophs

Which gas is removed from the atmosphere during photosynthesis?

• hydrogen
• oxygen
• nitrogen
• carbon dioxide
