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.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

i believe the answer is c

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
