Part I: Create four separate graphs based on the data obtained from Canvas:

1. Specific Gravity vs. Time (line graph: use data for all groups)
2. Urine Volume vs. Time (cumulative line graph: use data for all groups) Note: you will have to add the urine volumes together to obtain the cumulative volume (e.g. the cumulative volume at 60 minutes would be the sum of the individual volumes at 20 minutes + 40 minutes + 60 minutes)
3. Urine Production Rate vs. Time (line graph: use data for all groups)
4. % return (bar graph: only 500 ml and 1000 ml water loading groups)

On each graph include the data supplied by the other groups. (See Canvas)

Add a title to each graph

Label each group with a distinct symbol

Provide a legend for your graph

Make sure you label your axes with the correct units (i.e. “Time (minutes)”, “Urine volume (ml)” and “Urine Production Rate (ml/minute).” (Note: Specific gravity has no units)

Part II: Graph summary paragraphs for each of the four graphs.

In a separate section under the heading Summary, write a separate one paragraph summary for each of the graphs.

I uploaded the urinalysis data that u need to use it for graphs and I uploaded another file is how we collect these data to better understanding (you don’t need to solve it or anything)

SO, you need to make 4 graphs and each graph has it own summary

Run this simulation as an apprentice from beginning to end which is level 6. This means there are  6 questions. After, run the simulation as a Master which has 5 questions. It will only take around 11 minutes to complete. This simulation is great for developing your understanding of the vector directions of velocity and acceleration.

1) Describe the differences between the Apprentice Level and Master Level in the simulation. In your Initial Post describe how the placement of the dots and the vehicle’s direction of motion helps you to determine the direction of velocity and the direction of acceleration.

2) Reply to a classmate who doesn’t have a reply. Correct any errors or misconceptions they may have made in their initial post. If they didn’t make a mistake or have a misconception then let them know what they explained particularly well and explain why. Also, include a description of what a position vs time graph and a velocity vs time graph would look like for one of the 6 situations in the apprentice simulation. (Do not simply copy what a classmate wrote. It’s obvious when you do. Your posts are time-stamped so it’s easy to know who provided their reply first. Address these questions on your own so that you can learn these concepts.) (for this section#2: reply to classmate i have to send it later when the classmate submit their answers )

List and describe 5 things you can (and are willing to do) that will contribute to a reduction in anthropogenic climate change. Create a numbered list of your answers. Your answers should be specific to you and should be actionable, meaning you have indicated specifically how you will accomplish this or what it will look like in your life. Be thoughtful and honest in your response. Ideally, you are creating a list of things that you will actually implement!
