Concept explainers
To determine:
The rate at which the body temperature will return to normal if out of desperation an individual have dunk his head into the cooler to get relief from heat.
Introduction:
In living organisms the
The endotherms are the animals that maintain their internal body temperature by thermoregulation as sudden change in the body temperature could be fatal for an organism. Endotherms get heat from the internal metabolic activities if the outside temperature is low and cool down their bodies by process of sweating if the outside temperature is high.

- Which of the following is not true about acclimatization? Acclimatization allows animals to compensate for changes in their environment Acclimatization improves function in a new environment Acclimatization occurs when an animal tries to reestablish a homeostatic set point Acclimatization is passed on to offspring of acclimated individuals.arrow_forwardHow long can you go? You may have heard the exploits of free divers, who dive to tremendous depths without any aid of scuba equipment. The world record for assisted free diving is held by Pipin Ferreras, who dove 170 m (558 ft) with the aid of a sled. Free diving is not without its dangers. Pipin’s wife Audrey died during a world record attempt. Free diving is facilitated by the dive reflex, which allows mammals to hold their breath for long periods of time underwater. Immersing one’s face in cold water includes bradycardia and diverts blood away from the periphery. How would these modifications increase the ability to free dive?arrow_forwardCheck Your Understanding 1. How do homeostasis and metabolism work together to keep an organism alivo 2. List and explain four methods that an organism such as a cat uses to stav warm on cooler days. 3. Many exercise and weight-loss programs encourage speeding up an individual's metabolism. Explain how a person could lose weight by increasing their exercise routine. sformationsarrow_forward
- Think about what happens to your body when you run a marathon or participate in the Tour de France bicycle endurance race, then answer the following five questions: 1)Should you replace the water lost with sweating, yes or no? 2) How should you replace the water lost, all at once, continually during the race, or after the race? 3) Should you replace it quickly, or slowly? 4) Is there a need to replace electrolytes in the replacement water? What about glucose? 5) Is Gatorade the best choice to replace fluids, is it good for you, or detrimental to your health?arrow_forwardconstrict The regulation of body temperature is an example of a(n) mechanism because an above-normal body temperature stimulates mechanisms to decrease it, while a below- normal temperature causes changes to bring it up. dilate Вook positive feedback Print The thermostat is located in the part of the brain called the blood vessels erences hypothalamus When the core body temperature falls below normal, the negative feedback of the skin constrict and then receive nerve impulses to induce shivering to generate heat. sweat glands skeletal muscles When the body temperature is higher than normal, the blood vessels of the skin and the nervous system activates to cool the body by evaporation. cerebellum Resetarrow_forwardAll else being equal, a warm chameleon sitting on a sunny tree branch will experience a decrease in body temperature due to conduction if: It changes color, and its new hue is a lighter color, reducing the amount of energy the chameleon absorbs from the sun. The branch is cooler than the chameleon, and heat moves directly from the warmer animal to the cooler branch. It opens its mouth, allowing water to evaporate from its tongue and cheeks. OA cold breeze moves over the chameleon, transferring heat from the warmer chameleon to the cooler, moving air.arrow_forward
- Your feedback loop descriptions should include the following terms: thirst, ADH, hypothalamus, neuron, pituitary gland, nephron, kidney, urine, reabsorption, osmoreceptors. I have to Idea how to make a feed back loop about thisarrow_forwardCan you help me, please?1. What happens when our body deviates away from homeostasis?2. Which feedback loops mostly help in bringing things back to homeostasis?arrow_forwardYou said that "Exposure to an extremely salty environment, on the other hand, could potentially harm them by disrupting their internal environment and causing dehydration or an ion imbalance." I can't seem to find this anywhere do you have a research paper or source to show this? Thanks for your time and help I appreiate itarrow_forward
- Many marine fish swim into deep, cold water to pursue prey or avoid predators. How does cold temperature influence their ability to swim? What other affects will the cold water have on their body?arrow_forward*What's your normal body temperature? It may not be 98.6 °F, the often-quoted average that was determined in the nineteenth cen- tury. A more recent study has reported an average temperature of 98.2 °F. What is the difference between these averages, expressed in Celsius degrees?arrow_forwardHumans 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.arrow_forward
