What 3 categories do biological rhythms fall into? There are three types of biological rhythms: Circadian rhythms: biological cycles that occur about every twenty-four hours. Sleep follows a circadian rhythm. Infradian rhythms: biological cycles that take longer than twenty-four hours. Ultradian rhythms: biological cycles that occur more than once a day. What is an example […]
What are the behavioral adaptations of a giraffe?
What are the behavioral adaptations of a giraffe? A behavioral adaptation giraffes make when they drink water is to gulp it. Gulping is drinking a lot of liquid quickly without choking. Giraffes gulp as much as 10 gallons of water in a few minutes. They have also adapted the ability to go a long time […]
Which foods are high in enzymes?
Which foods are high in enzymes? Foods that contain natural digestive enzymes include pineapples, papayas, mangoes, honey, bananas, avocados, kefir, sauerkraut, kimchi, miso, kiwifruit and ginger. Adding any of these foods to your diet may help promote digestion and better gut health. Can digestive enzymes be harmful? Digestive enzyme supplements also could interact with antacids […]
Is it possible for a heat engine to operate without rejecting any waste heat to a low temperature reservoir explain?
Is it possible for a heat engine to operate without rejecting any waste heat to a low temperature reservoir explain? It is not possible for a engine to operate without rejecting any waste heat to a low temperature reservior. It violates the second law of thermodynamics, the operation of a heat engine a low temperature […]
What is the evidence that light is a wave?
What is the evidence that light is a wave? In 1801 a physicist in England, Thomas Young, performed an experiment that showed that light behaves as a wave. He passed a beam of light through two thin, parallel slits. The bright and dark bands demonstrated that the slits were causing light waves to interfere with […]
Which two factors are needed to calculate the velocity of an object?
Which two factors are needed to calculate the velocity of an object? The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is a physical vector quantity; both magnitude and direction are needed to define it. Speed, the […]
How do you increase surface area?
How do you increase surface area? The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder. How can you increase the surface area of water? Surface tension is the energy […]
What is the best form of power?
Does higher pressure mean more flow?
Does higher pressure mean more flow? Flow rate is the effect. Higher pressure causes increased flow rate. If the flow rate increases, it is caused by increased pressure. What is the relation between speed and flow rate? Flow rate and velocity are related by \(Q=A\overline{v}\\\) where A is the cross-sectional area of the flow and\(\overline{v}\\\) […]
Why does temperature increase with mass?
Why does temperature increase with mass? If density increases ,volume decreases and if density decreases , volume increases. So density*volume=mass remains same as before. Gravitational pressure increases the more mass there is, and that pressure creates energy that increases temperature. Why does it take longer to heat up a larger volume of water? Simple: you’re […]
