Abstract: The experiment was conducted by using frog’s legs to understand how the muscle response to different levels of stimulations‚ and the levels of the twitch is also related to the number of motor units recruited. We used the program LabScribe to collect the data from the graph‚ and we also used the stimulator to stimulate the muscle through computer. We found out when the response reached the threshold and plateau. For the second experiment‚ we increased the Frequency from 0.5 Hz to 1Hz

Discovery of New Poison Dart Frog Biologists have discovered a new species of dart frog in the headwaters of the Rio Cano in Panama. This newly found frog has been named Andinobates geminisae after Geminis Vargas. Geminis Vargas is the wife of Marco Ponce who supported him toward the discovery of the new dart frog species. The new dart frog is very small about 12.7 millimeters in length and it is about the same size of a fingernail. Although the new dart frog is very small in size; it contains

El Valle‚ when she went to the main street there were golden frogs that basically represented their local street‚ and people even made souvenirs of them‚ but then she noticed that the population of the frogs had decreased. In the town of el Valle there were always golden frogs‚ she liked those frogs so much that she went on and established a research site so later she could study them. Lips decided she wanted to study the local frogs

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

California Red Legged Frog The California red-legged frog is the largest native frog in the western United States. The Records of the California red-legged frog are known from Riverside County to Mendocino County along the Coast Range of California. It has been on the endangered species list with a list of other endangered frogs. California red-legged frogs live in a Mediterranean climate‚ which brings about temporal and spatial changes in habitat quality which is why there species count was endangered

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

The story that will be analyzed in this essay paper is “The Notorious Jumping Frog of Calaveras County. The main analysis points in this paper will be focusing on the points of view in the story‚ also how would the story be different if someone else told it. The major themes that were in the story were dishonesty and cheating. In the beginning of the story‚ a man whose name is not said walks up to another man whose name is Simon and starts talking to him. Since the story uses the letter/word “I”

The Anatomical and Physical Features of Frogs Abstract: People have always wondered how frogs have the capability to live in both wet and dry environments. So why not dissect a frog to find out how. Frogs have both physical features like their skin that allows them to breath in water. They also have anatomical features like humans that allow them breath air just like us. Introduction As many people have learned throughout elementary and middle school amphibians are animals that have the

Results A left gastrocnemius muscle of a frog (L=3.2cm in situ) was used in experiment 1 and 2‚ while a right gastrocnemius muscle of a frog (L=3.4cm in situ) was used in experiment 3. The sciatic nerve of the frog was placed over the stimulatory electrodes covered with a piece of a Kimwipe moistened with Ringer’s solution. The relationship between muscle length‚ force production and velocity of contraction was studied. Force transduced calibration In order to get a more accurate data from force
