Tour de france riders consume about 5,200 calories per day of the race. calculate a rider’s average power intake in watts over the 21 days of the tour. [power intake is the rate at which the rider consumes energy in the form of food. the actual energy used to propel the rider’s bike, kinetic energy, is less than the energy they eat. there is some energy loss due to inefficiencies in converting between food and usable energy, maintaining body heat, etc. but we ignore this here.](5 points)

Sensory adaptation of cutaneous temperature receptors some types of sensory receptors, like pain receptors, will continue to transduce pain until the stimulus is removed. other sensory receptors may respond with an initial burst in production of action potentials, but will “adapt” and over time action potentials will cease. sensory adaptation occurs, for example, with olfactory receptors for smell. procedure have the subject place one hand in an ice bath while simultaneously placing the other hand in a warm water bath (@40oc). the subject should keep their hands in the designated baths for two minutes. after two minutes, remove both hands and place both hands in a room temperature water bath. record your observations review questions 1. describe how each hand felt after taking them out of the designated water baths and placing them into the room temperature water bath. 2. define sensory adaptation and relate it to what happened to the temperature receptors in the subject’s hands. 3. list and describe sensory receptors that adapt, and sensory receptors that do not.

Will treating a viral infection with antibiotics affect the course of the infection? a) no; antibiotics work by inhibiting enzymes specific to bacteria. antibiotics have no effect on eukaryotic or virally encoded enzymes. b) no; antibiotics do not kill viruses because viruses do not have dna or rna. c) yes; antibiotics activate the immune system, and this decreases the severity of the infection. d) yes; antibiotics can prevent viral entry into the cell by binding to host-receptor proteins.
