Lab 4: Skeletal Muscle Function Exercise 5: The Length-Tension Relationship Materials and Methods In this experiment I used a frog anesthetized with ms222. The frog’s skin is cut and removed from both the legs‚ the Achilles tendon is cut and the tendon and calf muscle are removed from the lower legs. The femur muscle is also cut. Attached to the legs are femur clamps which are connected to the transducer arm‚ stimulation electrodes are then positioned against the muscle. I plugged the output

Estimating Osmolarity of Plant Cells Criteria Assessed: DCP Introduction In this experiment you will be estimating the osmolarity of potato cells by finding their change in weight in solutions of known molarity. The object is to find the molarity where the mass does not change. No net change in weight indicates that there has been no net gain or loss of water. This is a means of indirectly finding the osmolarity of the cells themselves. Apparatus 1 large potato Petri dish 7 x 250 ml beakers

pH and Microbial Growth Introduction: Each organism has an optimum environment for growth‚ which includes pH level. Organisms that grow at near neutral pH levels are called neutrophiles. Those that grow best in acidic pH values are called acidophiles. Others‚ yet‚ grow best in alkaline pH values and are called alkaliphiles. In this lab‚ each group was assigned an organism‚ which was then used to inoculate 6 different pH levels. Materials and Methods: Followed lab procedure 29‚ “pH and
