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.

Why is it essential for organisms to maintain a relatively constant body temperature? Describe adaptations that help the organisms cope with changes in environmental temperature.
Consider the following scenario:
A group of five treasure hunters have been hired to retrieve some artefacts believed to be in an abandoned castle in an environment similar to the Arctic tundra (this is a quasi-fantasy land where disparate climates can co-exist in ways they can’t in reality, but everyone is human and has human physiology). Their expedition is happening in winter, and the group set out each carrying a pack of supplies including tents, sleeping gear, and food for either 3 well-fed days or up to 8 days with rationing (approximately 30kg each).
The treasure hunters travel on foot to get to the castle through lands where there are predators such as wolves and bears. They have two options in terms of speed of travel: slow (7 days to castle), and fast (4 days to castle).
1) As an advisor to the group, which speed would you say they should travel? Note – neither speed is wrong however your answer must justify your choice in terms of physiology.
Once the group get to the…

- According to your hypothesis about the relationship between temperature and the rate of cellular respiration (as temperature increases, rate of cellular respiration increases and vice versa), answer the following questions: What was the reason that you thought your independent variable would affect the dependent? That is, what cell structures do you think would be affected by the independent variable you chose? (Think of enzymes, membranes, organelles, etc.) What was the reason for the relationship you chose? That is, why did you think the independent variable would make the dependent increase or decrease? What would the results (and graph) look if they did NOT support your claim/hypothesis?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.

- Endothermy and Ectothermy are two strategies that organisms use to generate or maintain their internal body temperature. An ectotherm is an organism that derives very little of its body temperature internally, and relies on the environment for heat. An endotherm is an organism that maintains its own body at a metabolically favorable temperature by internal means. Question: How does temperature affect endotherms and ectotherms differently? Describe the evidence that will help you make a claim about the question: How does temperature affect endotherms and ectotherms differently?arrow_forwardIs Thermal Homeostasis of a Gold Fish similar to thermal homeostasis in human? If not, what is the difference?arrow_forwardYou are studying a large tropical reptile that has a high and relatively stable body temperature. How do you determine whether this animal is an endotherm or an ectotherm? (A) You know from its high and stable body temperature that it must be an endotherm. (B) You subject this reptile to various temperatures in the lab and find that its body temperature and metabolic rate change with the ambient temperature. You conclude that it is an ectotherm. (C) You note that its environment has a high and stable temperature. Because its body temperature matches the environmental temperature, you conclude that it is an ectotherm. (D) You measure the metabolic rate of the reptile, and because it is higher than that of a related species that lives in temperate forests, you conclude that this reptile is an endotherm and its relative is an ectotherm.arrow_forward
