How well did the results compare with your prediction? The thyroidectomized Tx rat is You correctly answered: a. The filtrate flows from the Bowman's capsule into the renal tubule called the proximal convoluted tubule then into the loop of Henle, and finally into the distal convoluted tubule: a. Most of the tubular filtrate is reabsorbed to prevent fluid loss and maintain homeostasis. Drag the first slide patient A to the fluorescent microscope. The nature of plasma membrane. Which of the following caused a change in membrane potential from -70 to -40 in the cell body? Increasing extracellular K+ causes the membrane potential to change to a less negative value because the K+ ions diffuse out across the membrane. The normal rat is You correctly answered: c.
Your answer: needed in order to remove any non specific binding that may have occurred. Explain the effect that the flow tube radius change had on flow rate. Which patient samples contained the Chlamydia-specific antigen? An introduction that defines a problem, stresses its importance, and offers a brief description of the proposed solution. After you click Submit Data, the slide will automatically be placed in the biohazardous waste disposal. The selective plasma membrane If you put the same amount of glucose in the right beaker as in the left, would you be able to observe any diffusion?.
Students gather data, analyze results, and check their understanding all on screen. Less negative What happens to diffusion of K+ leaving the cell if you increase extracellular K+? It diffused to the right beaker Why does this occur? Cell Transport Mechanisms and Permeability 2. Serological Testing Major changes to PhysioEx content since version 8. PhysioEx allows students to repeat labs as often as they like, perform experiments without harming live animals, and conduct experiments that are difficult to perform in a wet lab environment because of time, cost, or safety concerns. The increase in radius resulted in an increase flow rate, as predicted. You answered: 15 elementary bodies 17.
There is a difference in pressures at the ends of the vessels. Na+ and K+ both have a relative permeability of 0 voltage outside a resting neuron and a relative negative permeability inside a resting neuron. Which of the following has an epitope? With our help, your homework will never be the same! Which respiratory process is impaired the most by emphysema? What are the components of the renal corpuscle? By adding more extracellular K+ the intracellular K+ will decrease and cause the membrane potential to become less negative. The size of the molecule. What are two primary functions of the kidney? Experimental data can be recorded on screen and printed out as hard copies.
Which of the following statements is true? If all other variables are kept constant, how does blood pressure affect the rate of glomerular filtration select all that apply? After the student performs a step, instructions for the next step appear. You answered: 19 elementary bodies 19. When the radius of the afferent arteriole was increased, the pressure and the filtration rate both increased. What would most likely happen if you forgot to fix the samples to the slide? How well did the results compare with your prediction? This might result from a decrease in the radius of the efferent arteriole. How well did the results compare with your prediction? Activities 3 and 4 Examining the Effect of Surfactant and Investingating Intrapleural Pressuer were consolidated into a single activity, Activity 3: Effect of Surfactant and Intrapleural Pressure on Respiration. What happened to the left side of the bell jar when the valve was opened? Your answer: The resting membrane potential depends on the intracellular and extracellular. Submit this completed document by the assignment due date found in the Syllabus.
This is required to maintain homeostasis. Activity 5 Exploring Various Breathing Patterns was removed. The size of the molecule. Hint: Look at the relationship of the variables in the equation. NaCl , Urea , Glucose Which did not? Is it more beneficial to continue leasing the business space or to buy the building? Why do you think the plot was not linear? B Membrane of most cells contains K+ leak channels….
Which sample showed some residual nonspecific binding after the washing steps? 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. This is due to more room inside of the vessel for blood to travel. They will stain green in red host cells. Explain how the body establishes a pressure gradient for fluid flow. In the serology test just performed, the fluorescence is found on the You correctly answered: c.
Less negative What happens… Exercise 12: Serological Testing: Activity 1: Using Direct Fluorescent Antibody Technique to Test for Chlamydia Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. An increased efferent arteriole radius will decrease the rate of glomerular filtration. An increase in extracellular K+ 3. Predict Question 2: Do you think the addition of glucose carriers will affect the transport of sodium or potassium? Activities 7-9 Respiratory Response to Normal Metabolism, Respiratory Response to Increased Metabolism, and Respiratory Response to Decreased Metabolism were consolidated into a single activity, Activity 4: Respiratory Responses to Metabolic Acidosis and Metabolic Alkalosis. A decreased efferent arteriole radius will increase the rate of glomerular filtration.
