Question
If this animal added a thick fur coat and became more cold acclimated with a Lower critical temperature of 10 degree x with no change in BMR it would have a heating cost of ______ MRU/degree, please just type in a number for your answer, not the units. Please answer using a decimal value (e.g. 0.2). 2.5000 Same graph as previous question but the LCT change and BMR change numbers are generated by the computer If this animal became more cold acclimated with a Lower Critical Temperature reduced by 6 degree x by means of adding brown fat and fur, raising it's BMR by 7MRU, it would have a heating cost of _________ MRU/degree You are welcome to use a calculator for this problem. Use two decimal places in your answer, unless it is a whole numberExplanation / Answer
1) The basal metabolic rate of the organism is 25 MRU. The body temperature of this organism is 30. Therefore, when that organism becomes more cold acclimatised with a lower critical temperature of 10 degrees with no change in BMR, the heating cost is,
= 25/(30-10)
= 25/20
= 1.25
