What is physiology correct answers the study of how organisms work e.g. structure and function What are the three design rules for plants and animals correct answers 1. they must obey physical and chemical laws (including scaling)- diffusion, thermodynamics, pH, temp 2. they must meet demands but be economical (with appropriate safety factors) 3. they are constrained by evolutionary history What is the first law of thermodynamics correct answers Energy cannot be created or destroyed ...

___________ and _________ are inversely proportional; _________ and _______ are directly proportional - frequency and wavelength ; frequency and energy 1st Law of Thermodynamics - delta-U = q + W heat transferred + work done by system on surroundings - W is positive if work is done on the system (by surrounding) - W is negative if work is done by the system A system doing work pushes back on surroundings, it ___________. When surroundings do work, pushes back on system, it _________ . - e...

an energy imbalance results in correct answer: weight gain or weight loss energy intake is more than energy expended correct answer: positive energy balance positive energy balance results in correct answer: weight gain periods of growth for positive energy balance correct answer: pregnancy, childhood, and adolescence energy expended is more than energy intake correct answer: negative energy balance negative energy balance results in correct answer: weight loss kilocalori...

Energy From Food - 4 kcal/g - Carbs 4 kcal/g - Protein 9 kcal/g - Fat 7 kcal/g - Alcohol 2 kcal/g - Sugar Alternatives Vitamins, Minerals, and Water are not 'energy-yielding.' How nutrients become energy? - bonds between nutrients are broken, so energy is released. What happens to Excess energy? - it is stored as fat, acutely and long-term Bomb Calorimeter - Direct measurement: food burns, then releases heat energy. It's not exact because everyone has a different metabolism (effici...

1. Question: A sample of oxygen gas has a volume of 3.52 L at 27°C and 800.0 torr. How many oxygen molecules does it contain? 2. Question: Consider a sample of gas in a container on a comfortable spring day. The Celsius temperature suddenly doubles, and you transfer the gas to a container with twice the volume of the first container. If the original pressure was 12 atm, what is a good estimate for the new pressure? 3. Question: Gas A and gas B are combined in a flask at initial pressures of 1...
