Biology EOC Review Question set 1

The diagram shows a container divided into two compartments by a membrane permeable to water but not to starch. Two solutions containing different concentrations of dissolved starch were placed on each side of the membrane. Which of the following describes what will happen to the water level during the process of osmosis?  

• The water level of both sides of the membrane will decrease 
• The water level on the right side of the membrane will increase 
• The water level on the left side of the membrane will increase
• The water level on both sides of the membrane will stay the same 

An animal cell placed in a sugar solution is shown in the diagram. Which statement best describes how osmosis will affect this animal cell?  

• Water will move out of the cell and the cell will shrink
• Water will move into the cell and the cell will expand 
• Sugar will move out of the cell and the cell will expand 
• Sugar will move into the cell and the cell will expand

In order to make hydrochloric acid, which is required in human digestion, ATP is used to move hydrogen ions from the blood to the stomach lining. This is an example of ___.   

• Active Transport
• Passive Transport
• Osmotic Potential 
• Facilitated Diffusion

 A paramecium is shown.  This paramecium lives in an environment where water is constantly entering the organism.  The paramecium uses specialized vacuoles to pump some of the water back into the environment against a concentration gradient. Which of these processes is used to pump extra water out of the paramecium?   

• Osmosis
• Diffusion
• Active Transport
• Electron Transport

A cell requires energy to move materials from an area of low concentration, across the cell membrane, to an area of high concentration.  This process is called ___. 

• Osmosis
• Active transport 
• Passive transport 
• Facilitative diffusion

In active transport, carrier proteins ___.  

• Move substances across the cell membrane without the use of ATP.
• Move from low concentration to high concentration by diffusion
• Move small molecules through the cell membrane by osmosis 
• Move substances from a low concentration to high concentration through the use of energy.

What will most likely occur when a cell is placed into a saline solution that has a higher salt concentration than inside the cell?    

• Water molecules will move into the cell
• Salt molecules will move out of the cell 
• Salt molecules will move until the salt concentration is the same inside and outside the cell 
• Water molecules will move until the salt concentration is the same inside and outside of the cell.

 An ion must cross the cell membrane through active transport instead of passive transport when the ion is ___. 

• Negatively charged
• Carried across by a protein 
• Going against the concentration gradient 
• Too small to move independently

The diagram shows the semipermeable membrane of a cell and the concentration of solutions inside and outside the cell. Which of the following statements best describes how the molecules will move?   

• Water molecules will move out of the cell 
• Water molecules will move into the cell 
• Solute molecules and water molecules will move out of the cell 
• Solute molecules and water molecules will move into the cell 

The stages of the cell cycle are shown in random order below.  Starting with prophase, sequence the diagrams to show the stages of mitosis.
