Which of the following conclusions can be drawn from the data shown in the figure?
The figure shows two pie charts. The first pie chart represents distribution of nitrogen entering the Chesapeake Bay by its sources. According to the pie chart, each source accounts for the following percentage of the entering nitrogen: Agriculture fertilizer and manure account for 32 percent, Atmospheric deposition agriculture for 6 percent, Atmospheric deposition mobile, utilities, and industries for 26 percent, Atmospheric deposition natural for 1 percent, Municipal and industrial wastewater for 19 percent, Urban and suburban fertilizer runoff for 10 percent, and Septic systems for 4 percent. The second pie chart represents distribution of phosphorus entering the Chesapeake Bay by its sources. The sources account for the following percentage of the phosphorus: Agriculture fertilizer and manure for 45 percent, Natural sources for 3 percent, Municipal and industrial wastewater for 21 percent, and Urban suburban fertilizer runoff and transported sediments for 31 percent.
Which of the following conclusions can be drawn from the data shown in the figure?
Agriculture accounts for 77% of the nitrogen and phosphorus entering Chesapeake Bay.
Automobiles do not contribute to nutrient pollution in Chesapeake Bay.
Full protection of Chesapeake Bay will require consideration of activities within the bay's airshed and not just the bay's watershed.
Repairing broken septic systems will probably result in a large decrease in phosphorus pollution entering Chesapeake Bay.
Wastewater treatment plants do not contribute significantly to nutrient pollution in Chesapeake Bay.
Answer:
Full protection of Chesapeake Bay will require consideration of activities within the bay's airshed and not just the bay's watershed
Explanation:
Let's consider the options:
A) Agriculture accounts for 77% of the nitrogen and phosphorus entering Chesapeake Bay. Agriculture accounts for 45% of phosphorus and 32% of nitrogen, so cannot account for more than 45% of the pollution from these sources.
B) Automobiles do not contribute to nutrient pollution in Chesapeake Bay. 26% of nitrogen comes from atmospheric sources. Automobiles are a large contributor to atmospheric nitrogen pollutants, so it cannot be concluded that automobiles are not a contributor.
C) Full protection of Chesapeake Bay will require consideration of activities within the bay's airshed and not just the bay's watershed. Since atmospheric sources are tied with fertilizer and manure as the largest contributor of nitrogen pollution, it seems clear that addressing these sources will be required.
D) Repairing broken septic systems will probably result in a large decrease in phosphorus pollution entering Chesapeake Bay. The contribution of septic systems is 4% of the total nitrogen pollution, so eliminating that source will not have a major impact.
E) Wastewater treatment plants do not contribute significantly to nutrient pollution in Chesapeake Bay. Wastewater treatment accounts for about 20% of the pollution, so we'd have to say that is a significant source.

Why is it important for scientists and others tp be skeptical of extraordinary claims?
Answer:
“Extraordinary” evidence is only required when it must be balanced against a very large number of contrary observations. The crux of the matter is that in order to properly characterize a claim as “extraordinary,” there must exist weighty evidence of the exact antithesis.
Explanation:
An extraordinary claim is one that is already contradicted by extraordinary evidence. Under this definition, our maxim basically says that the only way to counter evidence is with more evidence. I think that this is self-evidently true, and quite useful. For an example application, take astrology.

Who invented the steam engine? what purpose does it serve? How has it impacted society today?
Answer:
James watt made it
Explanation:
In 1698, British inventor Thomas Savery patented a steam-powered pump, which he described as an "engine to raise water by fire." Savery's very basic engine relied on steam to create a vacuum and pull water upwards through a pipe — a theory that had been around for several centuries but never successfully applied.
The steam engine was not created by a single person but instead developed through time with the help of several innovators. James Watt was one of the important protagonists in the steam engine's development, though.
James Watt significantly improved the design and effectiveness of steam engines in the late 18th century, which paved the way for their widespread usage.
The steam engine's function is to transform the steam's energy into mechanical work. It generates circular motion using the expanding force of steam created when water is heated, which may be used for a variety of purposes. Originally, the main use of steam engines was to remove water from mines.
The steam engine had a significant and far-reaching effect on civilization. These are some significant effects it has had on modern society:
Industrial Revolution: Steam engines' invention and widespread usage were crucial in starting the Industrial Revolution.
Transportation: Steam engines, which propelled steam locomotives and steamships, changed transportation.
Economic Growth: The steam engine's function in boosting transportation and powering industry helped to significantly increase the economy's growth and prosperity.

Identify the rectangular solid that represents the cell with the smallest amount of plasma membrane per volume of cytoplasm
Answer:
Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm
Note: The question is incomplete. The attachment below gives the complete question
Explanation:
The outermost surface of a cell is bounded by the plasma membrane which functions to maintain the integrity of the cell as well as control the movement of particles in and out of the cell.
The ratio of the surface area of a cell to the volume of the cell indicates how big the cell is. When the surface area to volume ratio is small, the cell is very big, but if the surface area to volume ratio is big, the cell is small.
From the attachment below, the surface area (plasma membrane) per volume of plasma of the rectangular solids are as follows:
Solid 1: 10/2 = 5 cm⁻¹
Solid 2: 12.18/2 = 6.09 cm⁻¹
Solid 3: 19.0/2 = 9.5 cm⁻¹
Solid 4: 34.24/2 = 17.12 cm⁻¹
Solid 5: 65.79/2 = 32.895 cm⁻¹
Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm

Then make a claim about the origin of cell compartmentalization based upon the evidence presented, stating two to three reasons for the claim. Provide evidence and specific examples that support each reason for the claim. Provide a conclusion to the short essay.
Answer:
Explanation:
Both organelles, the mitochondria and chloroplasts (in photosynthetic organisms), are compartments that are believed to be of endosymbiotic origin.A compartment is a separate space within a larger whole. In relationship to the endomembrane system and the nucleus.organelles that aren’t part of the endomembrane system, such as mitochondria and chloroplasts.Cellular compartmentalization allows cells to optimize the efficiency of the processes that occur within organelles. But despite the advantages of compartmentalization, it’s not a universal feature of life. In fact, compartmentalization of cellular functions into membrane-bound organelles is limited to only one of life’s three major groups, or domains. That domain is the one that we belong to, the Eukarya. In addition to animals, eukarya includes plants, fungi, and other organisms with eukaryotic cells: cells that are relatively large, complex, and compartmentalized. And to see why that is, we need to look at how life has diverged over time.

In research, scientists must always consider the evidence. So the correct option is B.
What is scientific evidence?Science investigates the laws and characterization of the observable and unobservable phenomena of the universe. Anything that is put forth as a fact or hypothesis must have testable measures so that it can be proved.
The tests performed in the case of scientific analysis give some results. If these results prove the hypothesis that was being tested, it's called a piece of positive evidence. If the results disprove the hypothesis being tested, it's called a piece of negative evidence.
Scientific evidence is of extreme importance in the case of the scientific method. No scientific theory can be accepted without sufficient evidence supporting it. The evidence is also required for disproving any kind of objections that may arise against the scientific theory.
Therefore the correct option is B.
