Biology Review - First Semester

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

Some microorganisms, such as yeast, produce energy in oxygen-free environments through the process of  

• Mitosis
• Photosynthesis 
• Aerobic respiration
• Anaerobic respiration

Proteins are made of monomers called ___________

• Nucleotides
• Monosaccharides
• Amino Acids
• Glycerol and fatty acids

DNA and RNA are examples of 

• Carbohydrates
• Lipids
• Proteins
• Nucleic Acids

Waxes, oils and fats are examples of

Genetic information is stored in which class of organic compounds?

• proteins
• lipids
• nucleic acids
• carbohydrates

How is chemosynthesis different from photosynthesis?

• Chemosynthesis does not require enzymes.

• Chemosynthesis can occur in environments without sunlight.

• Chemosynthesis does not require reactants from outside the cell.

• Chemosynthesis produces sugars that organisms use as an energy source.
