5 True/False Questions

1. nervous → 1. pumps blood, flushes urine out of the body, allows one to swing a bat; 2. major function is to contract

   True        False

2. areolar connective tissue → composes basement membranes; a soft packaging tissue with a jellylike matrix

   True        False

3. observations of egg in distilled water → the egg lost weight because the concentration of the egg, 14% is hypotonic to the 30% sucrose solution. Water moves by osmosis from an area of higher water concentration into an area of lower water concentration

   True        False

4. fibrocartilage → makes up the intevertebral discs

   True        False

5. dense connective tissue → 1. acts as a storage depot for fat; 2. insulates against heat loss

   True        False
