It is CO2 cycle
hope this helps
The answer is C: because growth at 37°C would be ideal for revealing bacteria that are human pathogens. 37°C is equivalent to 98.6°F, the normal body temperature for humans. If bacteria are reproducing at this temperature in a petri dish, they are also most likely reproducing in the body.
Cultures are made so doctors can be sure a person is sick with a specific bacteria often in order to make sure they are taking the right medication to get better. Choice A doesn't make sense, because we wouldn't want to kill the bacteria we are trying to study. Bacteria that makes us sick is harmful bacteria and is what we are trying to isolate. Choice B doesn't make sense, because they are only being incubated at one temperature, not a range or variety. Choice D is harder to rule out, but again the doctor wants the bacteria to reproduce so they can be sure that's what is causing the infection, so it wouldn't make sense that we would put the bacteria in a temperature they would not reproduce.
Answer:
The first one is: The hydrogen bonds that form between water molecules account for some of the essential — and unique — properties of water. ... The attraction created by hydrogen bonds keeps water liquid over a wider range of temperature than is found for any other molecule its size.
The second one is: Before it overflows, the water forms a dome-like shape above the rim of the glass. This dome-like shape forms due to the water molecules’ cohesive properties, or their tendency to stick to one another. Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.
The third one is: Water molecules want to cling to each other. At the surface, however, there are fewer water molecules to cling to since there is air above (thus, no water molecules). This results in a stronger bond between those molecules that actually do come in contact with one another, and a layer of strongly bonded water
This is the fourth: Water molecules are very good at forming hydrogen bonds, weak associations between the partially positive and partially negative ends of the molecules. Hydrogen bonding explains both the effectiveness of evaporative cooling (why sweating cools you off) and the low density of ice (why ice floats).

Explanation:
Loess is a periglacial or aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay and a balance of roughly equal parts sand and silt.
Answer:
The Burgess Shale of British Columbia is famous for its exceptional preservation of mid-Cambrian organisms. Around 40 other sites have been discovered of a similar age, with soft tissues preserved in a similar, though not identical, fashion.
