There are essentially two main sources of metabolic heat: A. The sun and insulation B. Baseline metabolic rate and specific dynamic action of feeding C. The sun and baseline metabolic rate D. Dynamic action of feeding and insulation E. Insulation and baseline metabolic rate

Many factors must be considered when attempting to predict the energetic needs of organisms - a primary goal of ecology. Below are two factors that must be considered. Compare and contrast how and why each effects the basal/standard energetic needs of endothermic regulators (homeotherms) and ectothermic conformers (poikilotherms)ā feel free to draw and paste in a graph(s) but be sure to reference them and explain what they mean in text (40 points). Body size Environmental temperature Explain how and why the effect of body size on energetic demands may affect the ability of individuals of different sizes (small and large) to cope with a shifting thermal environment in the face of climate change.

Question 22 (1 point) For an accurate measure of basal metabolic rate, you must reduce or block specific dynamic action. What would specifically reduce or block it? place on diet of protein with no carbohydrates place in a chamber of 100% oxygen during the metabolic measurement remove all food a few hours before measurement measure heat production rather than oxygen consumption Question 23 (1 point) The "3/4 law" was suggested by Kleiber and others. What does the fraction "3/4" refer to? the y-intercept of the linear relationship between log mass and log total metabolic rate the exponent of mass in the formula: total metabolic rate = a M^b the ratio of oxygen consumed to carbon dioxide produced the slope of the relationship between mass and mass-specific metabolic rate on normal linear scales Question 24 (1 point) Summer is coming and as things warm up, animals must make adjustments to maintain the viscosity (fluidity) of their cell membranes. First they add cholesterol, then what? increase fluidity by adding saturated fatty acids decrease fluidity by adding saturated fatty acids increase fluidity by adding unsaturated fatty acids decrease fluidity by adding unsaturated fatty acids Question 25 (1 point) The difference between poikilotherms and ectotherms is .... Poikilotherms do not regulate their body temp and ectotherms do not generate enough heat to warm themselves Poikilotherms regulate their body temp and ectotherms do not generate enough heat to warm themselves Poikilotherms do not generate enough heat to warm themselves and ectotherms do not regulate their body temp Poikilotherms generate enough heat to warm themselves and ectotherms regulate their body temp

a. What is the assumption upon which the measurement of metabolism is based with indirect calorimetry? -Most cells of the body are metabolizing glucose. -Most cells of the body contain mitochondria. -Heat is produced from each chemical reaction. -Metabolism is primarily aerobic. b. A man works outdoors for several hours on a hot, humid day. His core temperature increases from 37 to 38 degrees centigrade most likely because of which of the following? -His exertion is increasing his internal heat production. -He is breaking down brown fat to fuel his metabolism needs. -The ambient humidity is preventing exocrine sweat production. -Sympathetic output is constricting cutaneous blood vessels.
