Biology 2601A/B Lecture Notes - Thermometer, Electrochemical Gradient, Membrane Fluidity
Document Summary
Humans have flexibility; we can produce shlter, clothing, etc, we can survive in different temperatures. Other organisms live in extreme environments (like penguins- don"t build shelter but they cuddle together) Tree on the right lives in an extremely hot and dry environment. Heat is always transferred from warm to cool. Eqwuation: energy balance equation for any organism (or object) When the equation equals 0 the object is not gaining or losing energy. Direct radiontion from the sun, indirect radiation bouncing off of shit, radiation from the sky, amount of infared radtiation is dependent on the temperature of the object- you also emit radiation. Convective potential; windier it is the faster its moving heat away from you. Conduction; the transfer of nrg through solids (sit on a warm rock) Metabolism: some have metabolic heat and some dont. Latent heat loss (l): water evaporation or condensation. Thermometer slide: showing us the scales we will be working with.
