1. 1. A true-breeding homozygous
      tall pea plant is crossed with a
      true-breeding homozygous
      short pea plant.
2. 2. Two of the offspring from
      the previous cross are bred.

producing adequate surfactant. Why might this be a problem?

Experiment: Investigating Intrapleural Pressure

1. Describe what happens to air flow when one lung is “collapsed”.

2. What clinical term is used to describe the condition of:

1. a collapsed lung?
   

2. air in the pleural cavity?

3. Why does air enter the pleural cavity when the valve is open?

lung to reinflate?
