We go out to sunbathe on a warm summer day. if we soak up 80 british thermal units per hour [btu/h] of energy, how much will the temperature of 65 comma 000-gram person increase in 2 hours [h] in units of degrees celsius [°c]? we assume that since our bodies are mostly water they have the same specific heat as water (4.18 joules per gram degree celsius [j/(g degrees upper c)]).

The chemical effect of the endocrine system is longer lasting than the chemical effect of the nervous system. select the best answer from the choices provided t f

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
