Organism Physiology Paper The Physiological Evolution of the Crocodile Mother Nature diversity in regards to the animal kingdom is amazing. Throughout the Centuries‚ there have been changes to the globe and therefore to the habitat of the humans‚ animals‚ plants and all of the infinite organisms that live in our planet. However‚ even though there have been changes‚ the living organisms also have adapted to their new environment by changing their genetic composition and acquiring new characteristics

Activity 1: Electrical Stimulation 1. Do you see any kind of response on the oscilloscope screen? NO 2. What was the threshold voltage‚ or the voltage at which you first saw an action potential? 3.0 V 3. How does this tracing compare to the one that was generated at the threshold voltage? The tracing travel in the same fashion but the tracing were different with an increase threshold voltage 4. What reason can you give for the change? Increase voltage 5. Record this maximal voltage here:

Sample Physiology MCQs 1. Compound action potentials can be graded responses. True 2. The sciatic nerve contains axons of both afferent and efferent neurones. True 3. The absolute refractory period of an action potential is the period after an initial stimulus when it is impossible to evoke another action potential with a second stimulus. True 4. The refractory periods of individual axons are important as they dictate the maximal action potential firing rate of a neuron. True 5. Compound action

rod. 5. Describe the types of stimuli that generated an action potential. The different stimuli that generate an action potential are electrical‚ chemical‚ mechanical‚ and thermal. 6. If you were to spend a lot of time studying nerve physiology in the laboratory‚ what type of stimulus would you use and why? I would use chemical stimulation. I would want to see what different chemicals would cause an action potential versus chemicals that would not cause an action potential. And‚ whether

Fischer Lab Time/Date: 7:00 PM/Wednesday Activity 1 Metabolism and Thyroid Hormone Part 1 1 Which rat had the fastest basal metabolic rate (BMR)? The normal rat had the faster basal metabolic rate‚ because it was not missing its pituitary gland or its thyroid gland. 2 Why did the metabolic rates differ between the normal rat and the surgically altered rats? How well did the results compare with your prediction

Activity 1 Pre-Lab Quiz K+ inside a cell = 150 mM; K+ outside a cell = 5 mM Na+ inside a cell = 5 mM; Na+ outside a cell = 150 mM Stop & Think question What is the polarity of the resting membrane potential (voltage)? Negative What does it mean that the voltage just inside the membrane is negative? B Membrane of most cells contains K+ leak channels…..b What will happen to the resting membrane potential if the extracellular K+ concentration is increase? Less negative What happens
