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_forwardplease explain how body will maintain homeostasis with osmoregulation, like in the picturearrow_forwardEndothermic 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.

- All 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_forwardYour feedback loop descriptions should include the following terms: thirst, ADH, hypothalamus, neuron, pituitary gland, nephron, kidney, urine, reabsorption, osmoreceptors.
