Adaptations to cold conditions in Mammals Planning In this investigation I will depict adaptations/features, which mammals in cold places have, to reduce heat that they lose. Bigger animals have greater volume to carry out cellular respiration to produce heat. Cellular respiration is food (glucose) + Oxygen --> Carbon Dioxide + Water +Energy (heat). More cells = Big volume, the greater the volume, the more amount of heat loss is reduced. Smaller animals have larger surface area for them to lose heat to acclimatize to their hot climate. Large mammals have small surface area to volume ratio whereas smaller mammals have a large surface area to volume ratio. This table shows my observation is accurate. Cube size Surface area(cm2) Volume(cm3) Ratio(surface area/volume) 1 6 1 6 2 24 8 3 3 54 27 2 4 96 64 1.5 5 150 125 1.2 6 216 216 1 7 294 343 0.9 8 384 572 0.75 9 486...
