Consider a pulse of energy EL delivered by a laser during surgery. The energy is absorbed within a tissue volume of 1000 mm3, which is 80% water. Assume the heat capacity of the tissue (with and without water) is 4.35 kJ/(kg K). Describe what happens to the tissue when the pulse energy, EL, is applied at the different values of 0.1 mJ, 0.5 mJ, and 3.0 mJ.

Part a - which gene to compare? in this exercise, you will use the cytochrome c oxidase i (coi) gene to investigate relationships among salmon species. (this gene encodes a protein that functions in the mitochondrial electron transport chain.) you will compare the coi gene sequences from your salmon test samples to the standard sequences for each salmon species. in order for the coi gene to be useful for distinguishing among the different salmon species, which three statements must be true?
