Calculate the average change of dissolved oxygen per year in the lake over the course of the study. Show your work.
Answer:
the correct set up is (8.6 mg/L - 3.3 mg/L divided by 2014-1965) = 0.11 mg/L per year.
Explanation:
The formula to calculate the average change of dissolved oxygen per year in the lake is:
[tex]average \: change \: in \: dissolved \: oxygen = \frac{total \: change \: over \: the \: years}{total \: number \: of \: years} \\ [/tex]What is dissolved oxygen?Dissolved oxygen is the amount of oxygen gas that is present dissolved in a given volume ofwater as a solution.
Dissolved oxygen is especially important for aquatic animals as it provides the main source of oxygen required for respiration by these animals.
Due to human activities resulting in water pollution and heating of water bodies, the amount of dissolved oxygen in water bodies is on the decrease.
To calculate the average change of dissolved oxygen per year in a particular lake, the following formula can be used:
total change over the years/total number of yearsTherefore, the average change of dissolved oxygen per year in the lake gives a picture of how human activities affect aquatic life in the lake.

The volume of a gas-filled spherical balloon increases 6 cubic inches for each degree (Celsius) increase in temperature. If the temperature increases at a constant rate of 2 degrees per minute, then at what rate is the radius of the balloon changing at the instant when the volume is 36π cubic inches?
A. 1/π inches per minute
B. 1/2π inches per minute
C. 1/3π inches per minute
D. 1/6π inches per minute
E. 2/3π inches per minute
The rate at which the radius of the balloon is changing at the instant when the volume is 36π cubic inches is 1/3π inches per minute.
Change in volume of the sphere with temperature
The change in volume of the sphere with temperature is calculated as follows;
[tex]V = \frac{4}{3} \pi r^3\\\\[/tex]
Given;
[tex]\frac{dV}{dT} = 6 \ in^3/^0C\\\\\frac{dT}{dt} = 2 \ ^0C/\min[/tex]
Radius of the sphere when the volume of 36π cubic inches[tex]\frac{4}{3} \pi r^3 = 36 \pi\\\\r^3 = 27\\\\r^3 = 3^3\\\\r = 3 \ in[/tex]
Change in volume of the sphere with radius[tex]\frac{dV}{dr} = 4\pi r^2[/tex]
Rate at which the radius of the balloon is changing[tex]\frac{dV}{dT} \times \frac{dT}{dt} = \frac{dV}{dt} \\\\\frac{dV}{dt} = 6\ (in^3/^0C) \ \times 2\ (^0C/\min) = 12 \ \frac{in^3}{\min} \\\\\frac{1}{\frac{dV}{dr} } \times \frac{dV}{dt} = \frac{dr}{dt} \\\\\frac{dr}{dt} = \frac{1}{4\pi r^2} \times 12\\\\\frac{dr}{dt} = \frac{12}{4\pi r^2} \\\\Recall, \ r = 3 \ in\\\\\frac{dr}{dt} = \frac{12}{4\pi (3)^2} \\\\\frac{dr}{dt} = \frac{12}{36\pi }\\\\\frac{dr}{dt} = \frac{1}{3\pi} \ \frac{in}{\min}[/tex]
Thus, the rate at which the radius of the balloon is changing at the instant when the volume is 36π cubic inches is 1/3π inches per minute.

The analysis used in the graphs has taken into account “data gaps, random instrument errors, uncertainties in ocean surface temperatures, and adjustments for urbanization over the land” (IPCC 2001 Climate Change—The Scientific Basis Report). Why do you think it is important for the scientists to take these uncertainties into account?
The reason why it is important for the scientists to take these uncertainties into account is because:
The uncertainty of data is vital for science due to the fact that it pushes scientists to be more involved in further investigation and research.
It is vital to understand that scientific uncertainty is not that there is flaws in your work but it it means there is an an absence of certainty and as such finding it is important so that it will not lead to bigger issues such as climate disasters.
What is the good about uncertainty?The Measurement of uncertainty is vital to risk assessment and decision making.
A lot of firms do make decisions a lot and on daily basis using reports that has quantitative measurement data. If measurement of the results are not right, the decision taken may have risks increase and as such it is good to investigate uncertainty.

Why would safety be the number 1 priority in plant and soil science?
Answer:
If water and air deterioration have been described and studied for decades, soil contamination has become a priority only by late 1990s. Only in the last fifteen years, the importance of soil has been recognized as it represents the most important element for supporting life on Earth.2 Indeed, soil supports terrestrial ecosystems and human constructions, it regulates water cycle and carbon dynamics, decomposition takes place into the soil and the nutrients become available again. Soil provides food for human nutrition, and its quality represents a fundamental requirement for food safety, and therefore for animal and human health, even though not always this relationship is stressed enough
