Purpose: The purpose of this lab is to test what substances are necessary for muscle contraction. Hypothesis: Based off the frog muscle immersed separately in Solution A of ATP and distilled water solution‚ Solution B of ATP with KCl in distilled water and MgCl2 in distilled water and solution C of KCl and MgCl2 in distilled water‚ I hypothesize that solution B of ATP with KCl in distilled water and MgCl2 in distilled water will cause the muscle to contract. Introduction: This lab consisted of discovering

This will lead to: a. a right shift in supply curve b. a left shift in supply curve c. a movement in supply curve d. a movement in demand curve 2. Assume that A’s supply is constant‚ A and B are substitute goods. The decrease in B’s price will lead to: a. a rightward shift in A’s demand curve b. a rightward shift in B’s demand curve c. a leftward shift in B’s demand curve d. None 3. The Engel

Review Sheet Results (1) 1. List the hematocrits for the healthy male (sample 1) and female (sample 2) living in Boston (at sea level) and indicate whether they are normal or whether they indicate anemia or polycythemia. 1. The hematocrit value for the healthy male: 48 2. The hematocrit value for the healthy female: 44 Both values are normal because they are between the normal ranges: for males between 42-52% and for females between 42-47%. 2. Describe the difference between the hematocrits

oxygen increases so does the number of fish observed. However‚ when the dissolved oxygen reaches 14 ppm the number of fish decreases to 10. So‚ 6ppm and 14ppm‚ 8ppm and 16ppm‚ and finally 10ppm and 18ppm‚ have a similar number of fish observed. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. If the amount of dissolved oxygen is increased‚ then the number of fish observed will increase. 3
