A. Avril Crayfish Lab Report November 9‚ 2012 Dr. Marvin Results: Figure 1. Firing Rate of Tonic Receptor in Response to Stretch. The correlation between Firing Rate and Stretch of the slow adapting crayfish receptor for four different sets of data is represented in this figure. The recordings are taken at stretches of 2‚ 4‚ 6‚ 8‚ and 10 mm of the crayfish tail. The best fit lines for the different sets of data are as follows: Ali and Emily- Linear best fit line‚ Dave and Laura- Exponential

The major goal of science is to ask & answer questions about the physical universe that we live in. 2. How is observation different from imagination? Observation gathers only what data is obviously true. Imagination can go anywhere—factual or not. 3. Write an equation in words & then in symbols for the following sentence: The price of coffee beans is equal to the weight

increases kinetic energy. Since Ek is the energy of motion‚ the particles would increase their velocity and the number and force of collisions. However‚ the particles would not increase their spacing since the phase potential energy remains constant during each of these three phases. The potential energy does not decrease at any segment of the graph for Tert-Butyl Alcohol. Based off the observations‚ the

not just copy and paste the definition. 1.Gravity- Gravity is a force of attraction between two objects 2. Inertia- the resistance any object has to start moving when it is in a stopped position or to change direction when in motion. 3. Potential Energy- energy which results from position 4. Kinetic Energy- Energy that a body possesses by virtue of being in motion 5. Friction-a force that holds back the movement of a sliding object. 6. Force of impact- force of the object

Enlist its advantages? 1+1 marks b). briefly mention the three determinants of resting membrane potential. 3 marks Ans: Q.1.a. SATTATORY CONDUCTION: 1 mark Propagation of action potential along a myelinated nerve fiber from one node of Ranvier to other in jumping manner is called as saltatory conduction. r Node to node conduction. Also called saltatory / jumping conduction. All ion channels

stimulation on a frog’s sciatic nerve by looking at its compound action potential‚ the conduction velocity‚ and by quantifying the total and absolute refractory period between the nerve at room and cold temperature. An oscilloscope‚ preamplifier‚ and stimulator were used to stimulate the frog’s nerve located in the nerve chamber. Threshold voltage was determined by stimulating the nerve at increasing voltages until a compound action potential resulted. Absolute threshold was determined similarly by increasing
