Calculate the oxygen consumption per hour for this rat using the following equation. Adrenal cortex, Anterior pituitary, Endocrine gland 1426 Words 4 Pages Session 1- PhysioEx Exercise 11—Kyle 1. Describe the three phases of a skeletal muscle twitch. The movement of sodium and potassium maintained by the Na+ -K+ pump You correctly answered: e. I think this is wrong because an hour or a day should not decide wither the foetus. When a muscle fatigues the contractile force declines due to previous contractile activity.
Howwell did the results compare with your prediction? The thyroidectomized Tx rat is You correctly answered: a. Glucagon is a hormone You correctly answered : b. The extracellular Na+ did not alter the membrane potential in the resting neuron because the Na+ channels were mostly closed. A change in Na+ or K+ conductance would affect the resting membrane potential because if the membrane is permeable to a particular ion, that ion will diffuse down its concentration gradient from a region of higher concentration to a region of lower concentration. Are there any safety concerns associated with this exercise? Predict Question 2: In order to produce sustained muscle contractions with.
You can ask any homework question and get expert homework help in as little as two hours. The field of exercise physiology has always interested me, but I was never sure about what career path I would choose. Which of the following statements is true? Why did the metabolic rates differ? Experiment Results Predict Question: Predict Question: To measure the amount of plasma glucose in a patient sample Your answer : b. Stimulus frequency refers to You correctly answered: b. This also helps the offices run smoothly and free from errors. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? Increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels because the membrane is permeable to K+ ions. During the first 2 weeks on the job, the accountant made the following errors in journalizing transactions.
Sodium chloride, urea, glucose, and albumin Simulated Facilitated Diffusion 1. Drag the first slide patient A to the fluorescent microscope. Increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels because the membrane is permeable to K+ ions. Which of the following lists the anatomical structures in the correct order as they are encountered by the blood and filtered fluid during the process of filtration. An action potential in a motor neuron triggers the release of which neurotransmitter? Based on this E-R diagram, answer the following questions: a. If the grid in the data control unit is not empty, click Clear Table to discard all previous data. Phase 2 of the cardiac action potential, when the calcium channels remain open and potassium channels are closed, is called the You correctly answered: a.
The temperature of the solutions and the difference in concentration of the ion or molecule between the sides of the membrane 2. Refer to the appendix of this manual if you need a tutorial on how to make graphs in Microsoft Excel®. None of the rats developed a goiter with this injection. If the membrane is composed of lipid portion. Compare the baseline metabolic rates for the thyroidectomized rat and the normal rat and explain your results. Calculate the oxygen consumption per hour for this rat using the following equation. After the student performs a step, instructions for the next step appear.
Your answer: If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. How well did the results compare with your prediction? Because of the different organs that were removed from the two other rats that would produce certain hormones 3. The sodium-potassium pump is classified as a n You correctly answered: a. Human physiology focuses on how the human body. These values indicate diabetes mellitus.
C The revenue for selling game tickets online for a season can be recognized right away as most season tickets are nonrefundable. How could you treat a thyroidectomized animal so that it functioned. The normal rat is You correctly answered: b. A normal resting tidal volume is expected to be around You correctly answered: d. They have a section called Meditation 101. The term motor unit refers to Your answer : a.
The nervous system is a lot more fast acting and more rapid action occurs when compaired to the endocrine and the slow path. The hypophysectomized Hypox rat is You correctly answered: c. Question 15 of 32 0. Calcium channels open, increase of calcium into cell. Which respiratory process is impaired the most by emphysema? Employment Levels Regardless of where we are, unemployment occurs and. A cholinergic drug that worked the same as acetylcholine would You correctly answered: c. You answered: 19 elementary bodies 19.
Question 6 of 32 3. What is the approximate concentration of K+ inside a typical cell intracellular concentration? Which of the following statements about metabolism is false? Wave summation is achieved by You correctly answered: a. Now that you have calculated the oxygen consumption per hour for this rat, you can calculate the metabolic rate per kilogram of body weight with the following equation note that you need to convert the weight data from grams to kilograms to use this equation. Count the number of elementary bodies you see through the microscope recall that elementary bodies stain green , enter the number of elementary bodies in the field below, and then click Submit Data to display your results in the grid. How did the baseline metabolic rates of the three rats differ? Potassium channels closed, L-type calcium channels stay open. A skeletal muscle twitch is You correctly answered: a. For short answer responses, type your answer next to the….
Exercise 7: Respiratory System Mechanics: Activity 2: Comparative Spirometry Lab Report Pre-lab Quiz Results You scored 100% by answering 5 out of 5 questions correctly. Furthermore, there is no ability to negotiate for renewal. Now that you have calculated the oxygen consumption per hour for this rat, you can calculate the per kilogram of body weight with the following equation note that you need to convert the weight data from grams to kilograms to use this equation. Explain why the latent period became longer as the load became heavier in the experiment. Question 21 of 32 3.
