When looking at the three most abundant species found in both locations, there are significantly fewer Polychaete Larvae and Unidentified Copepod found at Fort Wetherill. Acartia was higher in abundance at Fort Wetherill, but remained dominant in both locations. Fort Wetherill is at the mouth of the estuary and is a nutrient exporter. It should have been expected that there would be less species surviving. Estuaries transport dissolved nutrients to coastal zones leading to a high productivity in primary and secondary production.
The amount of magma taken from beneath the summit has been small compared with the total amount of magma that has been erupted although the production rate of new magma has mostly kept up with the eruption rate. The rates of magma distribution could mean a very long lasting eruption. 8. Why does a fissure eruption's characteristics change over time? (page 100, para 1 to page 102) Over time magma can melt through the wall rocks and enlarge the plumbing allowing for more flow and a centralized vent such as the one in Hawaii.
This is because there will still be a lot nutrients and soil left behind from the previous ecosystem. Therefore less ammonification and nitrification will be needed as the soil will already be suitable for more complex plant species. Natural succession can therefore be altered by both nature and human intervention, take stud land bay psammosere ecosystem for example that is deliberately cut back so that you can
If the temperature was less than the water bath in some places because only part of the pipet was immersed in the boiling water, the molar mass calculated would become lower. This is because the ideal gas law temperature value would be too low, therefore lowering the overall
The light was different between the two sites because the canopy in the forest significantly reduced the amount of light that was able to shine through. This difference in light could account for the trend observed in air temp, shallow soil temp, and deep soil temp. Since there was more sunlight present in the grassy area, with minimal coverage, the temperature was higher in all three measurements compared to the forest
When we start an exercise our bodies cannot deliver oxygen to the muscles fast enough therefore it heavily relying on the anaerobic processes for the initiating actions. The emphasis then goes on the aerobic system if the exercise is at low intensity. This system is a bit slower than the anaerobic systems because it relies on the circulatory system to transport oxygen to the working muscles before it creates ATP. The aerobic energy system works at moderate intensity as it works for longer duration of time; therefore the intensity is equal to the amount of time the activity lasts for. The aerobic system can only work when the energy demand is at the intensity for which the heart is able to provide the muscles with sufficient supply of
a small washer was inserted between the water supply line and the existing showerhead. These worked poorly because pressures were reduced and existing heads did not deliver the desired feeling without the proper pressures. As a result, low-flow technologies got an undeservedly bad rap from which they are still trying to recover. New low-flow showerheads deliver only 1 to 2.5 gallons per minute. Although the amount of water that moves through these fixtures has been reduced, the velocity of the water has been increased.
A) is neutralized by water B) is surrounded by water molecules C) reacts and forms a covalent bond to water D) aggregates with other molecules or ions to form a micelle in water Answer: B Page Ref: Section 3 11 9) Which would you expect to be most soluble in water? A) I B) II C) III D) IV Answer: A Page Ref: Section 3 10) Solutes diffuse more slowly in cytoplasm than in water because of A) the higher viscosity of water. B) the higher heat of vaporization of water. C) the presence of many crowded molecules in the cytoplasm. D) the absence of charged molecules inside cells.
The rate at which the temperature changes seems to decrease slower and slower. The decreasing rate is the highest when the plastic is just placed into a chiller system. The cooling rate slows down approximately after 17 seconds. 2. Imagine a curve running thought the data points.
Being in a foraging society had some advantages and disadvantages and being in an urbanized society also had some advantages and disadvantages. In a foraging society they heavily relied on weather since they had to find there own food and that was a bad disadvantage. If there was good weather then they could go out and search for food but if there was bad weather then it would be extremely difficult to search for and get food and in the Paleolithic age, they needed all the food they could get in order to survive. In an urbanized society, they relied on weather too but they often would have surplus so they did not rely on it as much. In a foraging society, they had to hunt and gather their own food which was a big disadvantage because that means they had to constantly be moving around because one area could not keep a society alive for a whole lifetime.
