Why does life on land present particular difficulties in maintaining temperature homeostasis compared to life in water?
To determine:
Why life on land present particular difficulties in maintaining temperature homeostasis compared to life in water.
Introduction:
Homeostasis is the property of an organism, to resist any change in “internal” as well as “external environment” to maintain the state of equilibrium. Homeostasis is important as all kind of life forms can work efficiently under a “particular set of conditions” known as “optimum conditions”. The parameters for optimum conditions include temperature,
Explanation of Solution
Temperature on land varies from
Homeostasis is the ability of an organism to maintain proper body temperature with reference to surroundings. Different variables are taken as parameters for deciding homeostasis of an organism. These variables include temperature, fluid, and salt concentration

- 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. What is the difference between these averages, expressed in Celsius degrees?arrow_forwardEndothermy 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_forward
- Is Thermal Homeostasis of a Gold Fish similar to thermal homeostasis in human? If not, what is the difference?arrow_forwardfor aquatic animals such as sharks, how do the animals maintain their body temperature when they are in warmer or colder waters? do they have a method where they can decrease or increase their body temperatures slightly such as torpor in birds?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
- 1) It is _____for aquatic vertebrates to maintain a body temperature different from their surroundings because ______. A) easier; water is a much better insulator than air due to its greater density B) easier; it is possible for fish to absorb heat from the surrounding water by countercurrent exchange even when the water is colder than the fish C) harder; water is a better conductor of heat than air D) harder; terestrial vertebrates can use countercurrent exchange to absorb heat from air that is cooler than their bodies 2) Compared to terrestrial environments, marine environments have_____." A) greater differences in temperature between hot and cold seasons B) smaller differences in temperature between hot and cold seasons C) the same amount of seasonal variability in temperaturearrow_forwardAccording to the idea that there is a limited amount of energy available in the body, what are considered to be the major physiologic processes when an individual is in energy balance: reproduction, cellular maintenance, body temperature regulation, growth and locomotion. O growth, reproduction, protein synthesis and body temperature regulation. locomotion, growth, cellular maintenance and reproduction.

What do you think will happen if you increase/decrease the temperature of a goldfish’s water? 6.

- The range of regulated body temperatures in mammals is about 36 to 40°C , while in birds it is slightly higher, 38 to 42°C, close to the limit compatible with life. Why do you imagine birds maintain higher body temperatures thanmammals? Do you think eagles and hummingbirds maintain the same body temperatures? Explain.arrow_forwardDraw a negative feedback loop for maintaining homeostasis for thermoregulation where your body temperature is above the set point. In your drawing, include the stimulus, sensor, integrator, effector, and the arrows between the components to indicate how they all relate (be sure to indicate what each of these components are in your body, for example, what is your integrator). Further, answer the following two questions. First, what might be different between the response of an endothermic and an ectothermic animal in maintaining homeostasis? Second, describe what a negative feedback loop is and how it pertains to homeostasis.arrow_forwardHow do living organisms maintain homeostasis in a vast array of circumstances?arrow_forward
