Water is essential to life on Earth: its unique physi­cal and chemical properties act to protect living systems and are necessary to the struc­ture and function of cells. One unusual charac­teristics of water is that despite its low molecular weight, it is a liquid at most environmental temperatures. Other molecules having similar molecular weights, ammonia, methane, and hydrogen sulfide, are gases. Develop a logical explanation for water's existence as primarily a liquid in living systems. All BUT ONE response could apply. A) Water has the highest specific heat capacity of any liquid due to its polarity.

B) To change state, much heat energy must either be added or removed to change the nature of the hydrogen bonding.

C) The property of high specific heat capacity allows highly regulated internal body temperatures for all organisms.

D) Water has a high heat of fusion as well as a high heat of vaporization as a result of the hydrogen bonding among molecules.

The property of high specific heat capacity allows highly regulated internal body temperatures for all organisms. While this is a true statement, it does help to explain fwater's existence as primarily a liquid in living systems.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
