- You are designing an experiment to determine if you can make desert kangaroo rats active at noon. At noon the ground and air are warmer than the internal temperature of the rats. You decide to provide the kangaroo rats with enough water to ensure they can maintain body temperature homeostasis. Based on a simplified model, you determine that at noon, kangaroo rats: - Gain 8 watts of heat from radiation and 1 watt of heat from metabolism - Lose 1 watt of heat by re-radiation - Gain 6 watts of heat from the surrounding desert ground and air via conduction and convection The kangaroo rat is not in energy balance. Since kangaroo rats lose 1 watt through latent heat (i.e. evaporative cooling) with each 2 ml of water consumed, how much water would you need to provide the kangaroo rat so that it can reach homeostasis? 4 8. 12 24 28 O 32arrow_forwardFill in the blanks using the words provided, each word will only be used onceCellular respiration, energy, ATP, Glucose, Oxygen, Chemical, stored, heat.

- Study the diagram above. (You might also want to do a little research.) Write (this is an essay style assignment) a WELL THOUGHT OUT response comparing and contrasting the energy conversion (combustion) process that occurs in an automobile with the energy conversion process (cellular respiration) that takes place in your cells. Please make sure that you are using your own words, and not copying and pasting words from other sources. PROVIDE YOUR RESOURCES for any borrowed information. Your writing MUST include the following thought process: How can the two processes (combustion and cellular respiration) end up with the same products, but start out with different reactants?arrow_forwardDirections: Complete the paragraph below to explain why your body gets warm during a workout When you workout, your cells need !for muscle contraction.

- Endothermic animals can maintain consistent temperature conditions by generating, main- taining, and regulating their body heat. Which of the following describes the most likely mechanism by which endothermic ani- mals generate their body heat? A Chloroplasts that normally produce glucose molecules instead produce heat energy when required. B с D Catabolic reactions that provide usable chemical energy also produce heat. Enzymes that reduce the activation energy apply energy difference toward heat production. Lysosomes that normally digest nutrients and other intracellular material can be used to initiate apoptosis and thereby generate heat.arrow_forwardFor questions 10-14; indicate whether the sentence or statement is true or false. If false, rewrite the statement to make it correct. 10. Cellular respiration releases energy by breaking down glucose in the presence of carbon dioxide. 11. The products of glycolysis are 2 ATP, 2 NADH, and 2 pyruvic acid molecules. 12. If you swim aerobically for 30 minutes, your body has probably started to break down stored molecules, such as fats, for energy. 13. The first few seconds of intense exercise use up the cell's stores of fat. 14. During the course of a long race, a person's muscle cells will use both cellular respiration and lactic acid fermentation to produce ATP.arrow_forwardAnswer all questions.
