6. What regulatory processes would your body use if you were trapped by a blizzard in an unheated, uninsulated cabin in the woods (or in a heat wave with no air conditioning)

Shivering and sweating.

Explanation:

A prolonged exposure to extreme cold environment would activate the brain's heat-gain center. Your brain's heat-gain center causes shivering in order to increase our muscle contraction which leads to warming of our body.  Increase sweating is the regulatory processes our body use if it experience very high temperature. In order to regulate internal temperature of body, our body remove water which takes up heat with itself to lower th internal temperature.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
