False Clear my choice MacBook Air 20 F3 D00 000 F4 F5 VOne way to characterise biological tissue is to send a small electrical current through the tissue and measure the opposition to flow of that current through the tissue. In humans, the resistivity of fat is considerably greater than for muscle, which in turn is considerably greater than for blood and other body fluids. This can be used to analyse body composition, in particular, to estimate body fat percentage. (a) Using a simple model of fat versus non-fat tissue, draw a circuit diagram to represent the possible flows of current through the tissue.

Feedback inhibition, C. Kickback inhibition, D. Signal loopDraw a negative feedback loop for maintaining homeostasis for thermoregulation where your body temperature is above the set point. In your drawing, include the stimulus, sensor, integrator, effector, and the arrows between the components to indicate how they all relate (be sure to indicate what each of these components are in your body, for example, what is your integrator). Further, answer the following two questions. First, what might be different between the response of an endothermic and an ectothermic animal in maintaining homeostasis? Second, describe what a negative feedback loop is and how it pertains to homeostasis.Which of the following sentences is NOT correct? A.

- If daytime body temperature of some ectotherms were measured, the values would be fairly constant. Provide an explanation for such observations, giving some possible mechanisms that might be involvedwhich of the following statements are true about homeostasis? Select all that apply. a. The selective permeability of the cell membrane allows for thermoregulation. b. Homeostasis is an organism‘s way of maintaining constant and balanced internal processes. c. Ectotherms rely on environmental heat to maintain homeostasis. d. Homeostasis works by a system of positive feedback.Body temperature is homeostatically regulated around a set point. Given your knowledge of negative feedback and homeostatic control systems, predict whether narrowing or widening of the blood vessels of the skin will occur when a person exercises strenuously. (Hints: Muscle contraction generates heat. Narrowing of the vessels supplying an organ decreases blood flow through the organ, whereas vessel widening increases blood flow through the organ. The more warm blood flowing through the skin, the greater is the loss
