A local manufacturing plant reports a spill that released pollutant A into the local watershed. Pollutant A is a toxic substance. Local officials must determine if the residents should be evacuated from the area. Initial groundwater samples show pollutant levels at 5 mg/kg of water. Which decision is supported by the empirical evidence provided by the dose-response curve? Evacuation is not needed; continue groundwater monitoring. Residents should be evacuated until levels decrease. The spill no longer needs to be monitored. Residents should only evacuate above LD50.
Answers
The best decision that is supported by the empirical evidence provided by the dose-response curve is that residents should be evacuated until levels decrease.
The dose–response relationship is also called the exposure–response relationship. It shows the extent to which response (reaction) of an organism can be (reach), as a part of exposure to a stimulus or stressor in a given amount of time (exposure time). Dose–response relationships can be shown with the aid of dose–response curvesFrom the dose–response curve, we can see that the death rate is increasing, has reach the maximum peak and as such it is better to evacuate the residence from that contaminated place.
Conclusively, we can say that the best decision that is supported by the empirical evidence provided by the dose-response curve is that residents should be evacuated until levels decrease.

when attempting to control someone or something, do people compromise their own freedom in the process?
Answers
Perception differs for a lot of people. I believe that attempting to control someone or something, will not make one compromise their own freedom in the process.
Why attempt to control someone if you are going to loose your right to do whatever you want or be free. One's aim to control is to be able to do what you want.Freedom is the right of an individual to be free and even though it can be compromised by the evil intensions of other people, it is not right to so it to yourself. Lossing your freedom over something is not worth it. Though some people do compromise their freedom for anything but not in all situations.So therefore, I believe that people do not compromise their freedom at all and Lost of freedom is not what a person desires.

consider the following problem: a box with an open top is to be constructed from a square piece of cardboard, 3 ft wide, by cutting out a square from each of the four corners and bending up the sides. find the largest volume that such a box can have. (a) draw several diagrams to illustrate the situation, some short boxes with large bases and some tall boxes with small bases. find the volumes of several such boxes. (b) draw a diagram illustrating the general situation. let x denote the length of the side of the square being cut out. let y denote the length of the base. (c) write an expression for the volume v in terms of both x and y.
Answers
The largest volume that the box can have is two cubic feet.
(a) Please see the attached graph created with MS Excel that show the variation of volume with the side length of the square cut out.(b) Please find attached the diagram created with MS Visio, illustrating the general situation. (c) The expression for the volume v in terms of both x and y is V = y²·x.Reasons:
Given parameters are;
The side length of the box = 3 ft.
x represents the side of the cut square, we have;
Height of the box = x
Width of the box, y = 3 - 2·x
length of the box, y = 3 - 2·x
The volume of the box, V = y²·x
Therefore; V = (3 - 2·x)²·x = 4·x³ - 12·x² + 9·x
At the largest volume, we have;
[tex]\dfrac{dV}{dx} = \dfrac{d}{dx} \left(4 \cdot x^3 - 12 \cdot x^2 + 9 \cdot x\right) = 12 \cdot x^2 - 24 \cdot x + 9 = 0[/tex]
Which gives;
4·x² - 8·x + 3 = 0
[tex]x = \dfrac{3}{2}[/tex], or [tex]x = \dfrac{1}{2}[/tex]
The value, [tex]x = \dfrac{3}{2}[/tex], gives the minimum volume of the box, given that [tex]\dfrac{3}{2}[/tex] is half the length of the cardboard, therefore;
y = 3 - 2·x
We get;
[tex]y = 3 - 2 \times \dfrac{3}{2} = 3 - 3 = 0[/tex]
Which gives;
[tex]V = 4 \cdot \left(\dfrac{1}{2} \right)^3 - 12 \cdot \left(\dfrac{1}{2} \right)^2 + 9 \cdot \left(\dfrac{1}{2} \right) = 2[/tex]
The largest volume that the box can have, [tex]V_{max}[/tex] is 2 ft.³
(a) The volume of boxes with their height, (side length of square being cut out) x are plotted on the attached graph.
(b) Please find attached the drawings representing the general situation.
(c) From the question analysis, we have;
The volume of the box in terms of x and y is V = y²·x
The volume of the box in terms of x only is V = 4·x³ - 12·x² + 9·x
The volume of the box in terms of y only is [tex]V = y^2 \times \left(\dfrac{3 - y}{2} \right)[/tex]

A diagram of chloroplast stroma and thylakoid lumen showing chemical energy, ferredoxin, ferredoxin-N A D p reductase, A D P synthase, and oxygen-evolving complex. Which corrections would change the diagram to accurately model the light-dependent reaction of photosynthesis? Check all that apply. CO2 should be changed to H2O. ADP and ATP need to be switched. e– should be changed to H . Chemical energy should be changed to light energy. PSII and PSI need to be switched.
Answers
Given the process of photosynthesis is used to produce ATP in the presence of light and water, the first, second, and fourth options are what need to be changed.
Photosynthesis is the process by which certain organisms transform light energy into chemical energy in the form of ATP. The first option states that CO2 should be changed to H2O, which is correct. This is due to the fact that photosynthesis oxidizes H2O in order to produce a molecule of oxygen.
Option 2 is also correct in that the diagram should show ATP instead of ADP, given that photosynthesis is used by organisms to produce ATP as the primary energy product. To carry out the function, the enzyme used is ATP synthase, which is what the diagram should reflect.
Finally, we should also choose option 4, which states that chemical energy should be switched with light energy. As previously states, photosynthesis uses light energy to produce chemical energy. Though chemical energy is produced, it is the final product and does not participate in the process, light energy does.
