O growth, reproduction, protein synthesis and body temperature regulation. locomotion, growth, cellular maintenance and reproduction. O body temperature regulation, cellular maintenance and locomotion. cellular maintenance, growth and reproduction.
- Which of the following best defines metabolism? adjustments made by an organism to external or internal changes sum of all chemical reactions in the body process by which new cells replace old cells process by which cells become specialized to carry out specific functionsYour body stores energy in the form of fat and other organic molecules. When your body needs extra energy, it breaks apart the molecules of fat to release that energy (sometimes called "burning fat"). That energy is used to power cellular reactions or is lost as heat. The total amount of energy used by your body or lost as heat equals the amount of energy the molecules of fat originally stored before breaking apart. This process is an example of the _________law of thermodynamics. A. first B. secondselect all of the processes from below which describe changes which are independent of the path by which the change occurs. the elevation increase experienced by a traveller travelling from Grand Isle, LA to Denver, Coloradothe work generated by the body of an athlete as it metabolizes the sucrose in a cube of sugarthe heat generated by the body of a student during a chemistry examthe work accomplished in burning a gallon of gasolinethe energy evolved when a cube of sugar is oxidized to CO2(g) and H2O(g)the latitude increase experienced by a traveller travelling from Baton Rouge, LA to Anchorage, Alaskathe number of rotations the earth undergoes over a specified period of time
- When cells break down food (glucose) molecules during cellular respiration, energy is released in the form of heat and stored temporarily as ATP. released entirely as body heat into the environment. released quickly. stored temporarily in ATP molecules.As the temperature surrounding an endotherm decreases from its normal body temperature down to the freezing point of water, what happens to the amount of energy consumed by this animal? The amount of energy consumed decreases There is no change in the amount of energy consumed The amount of energy consumed increasesHomeostasis is a natural phenomenon which is body’s tendency to maintain internal stable and favorable environment against any situation that would tend to disturb its normal condition and function. Such as, If the temperature rises, the body loses heat by sweating or panting, via the latent heat of evaporation. If it falls, this is counteracted by increased metabolic action, by shivering and in fur or feather coated animals, by thickening the coat. Like temperature our body can sense the change in osmolarity and to maintain a stable condition body needs to persist on a certain osmolarity. Secretion of certain hormones can be stimulated by any change in the osmolarity to help maintain a certain level of osmolarity - briefly discuss the mechanism of action and biochemical function of such a hormone.
- Humans and some other animals use evaporative cooling to help regulate body temperature. Which statement regarding evaporative cooling is true? Evaporative cooling is possible because of the high heat capacity of liquid water. Evaporative cooling has a cost: the organism must ingest water and ions that are lost during sweating. Body temperature decreases during evaporative cooling because the water molecules with the greatest kinetic energy leave. the surface of the skin.Endothermic animals can maintain consistent temperature conditions by generating, main- taining, and regulating their body heat. Under cold conditions, more body heat becomes lost to the environment. Endothermic ani- mals rely on different mechanisms that allow them to maintain their body heat. Which of the following mechanisms that occur in endothermic animals does not describe a mechanism by which they maintain their body heat under these types of conditions? A B с D Some endothermic animals hibernate during extreme environmental conditions, which decreases the rate of metabolic reaction and decreases heat loss. The tissues of the blood vessels of many endothermic animals can dilate and move closer to the skin, allowing for heat to move more readily into the environment. Shivering, which can occur involuntarily in most endothermic animals, produces rapid muscle contractions, which increase the rate of cellular respiration and thereby increase heat production. Layers of densely packed…A recent newspaper article described a new bottled water that is “super charged” with oxygen. Since the body’s demand for oxygen increases as physical exertion increases, a university athletic coach thought that giving her athletes this oxygenated water would result in better performances. To test this idea, the coach divided her runners up into two groups. During practice, one group was given the super charged, oxygenated water to drink. The other group was given regular water. Both groups completed the same workout and drank the same amount of water (either oxygenated or unoxygenated). At the end of practice, she had all the athletes run 400 meters as fast as they could. She compared the times of the runners who had consumed regular water to those who had consumed the oxygenated water during practice. The coach found that the average time of the oxygenated water drinkers was significantly faster than that of the runners who had consumed regular water during practice. Which of…
