We have about 37 trillion cells in our body! The cell is the functional and structural unit of our body for a reason

We have about 37 trillion cells in our body! The cell is the functional and structural unit of our body for a reason – they do so many critical tasks to help keep us healthy and alive. Let’s dig a bit deeper into this wonderful world of cells.
Choose one organelle or cellular structure and give a descriiption – but do not identify it so your classmates can guess in their responses. Make sure you explain your chosen structure in enough detail (at least 2 sentences) so that others can figure out what you are pretending to be. Check back through the unit and make a guess on your classmates’ posts.
Find some current research involving stem cells and briefly describe how they are being used.
Would you use stem cell treatment if needed? Why or why not?
What are HeLa cells? Do some research and discuss:

Your task is to research a ‘Claim’. You will design an experiment with complete methods and hypothesis, collect data that can be analyzed with either Standard Error or Correlation Analysis, and draw sound conclusions from the results.

PROJECT OBJECTIVES AND DESCRIPTION
Your task is to research a ‘Claim’. You will design an experiment with complete methods and hypothesis, collect data that can be analyzed with either Standard Error or Correlation Analysis, and draw sound conclusions from the results. Your final product will be to create and record a video of your completed project presentation. This document describes in more detail each of the required project components and aligns with the ‘Investigating a Claim’ grading rubric.
Objectives & Directions: Identify a ‘Claim’ that you would like to investigate. If you look up the definition of the word claim, you will find that it is some kind of statement or assertion of truth that lacks supporting evidence. Our objective then is to start with a claim and conduct a short experiment to produce evidence that might support or refute that claim. This step will require some brainstorming and possibly online searching to first identify a claim to investigate, and also to determine whether the remaining assignment requirements can be accomplished (can I physically collect the data, can I accomplish this in the timeframe allowed, can standard error analysis or correlation analysis be performed, etc.). The sources of your claim might be word of mouth, social media, marketing/advertising, life-hacks, or anywhere you have learned of a claim you are interested in investigating.Or, you can develop a research question on your own. Due at the end of your regularly scheduled class time the week of March 11-15. Submit to the appropriate dropbox in D2L.

Describe the anatomy of the primary organ system

Organ System Assessment
Overview
For this assessment, submit an organized list of at least 10 bullet points, including the anatomical location of the particular organ system, the organs and structures in the system, the key cell and tissue types, and a diagram that represents the organ system’s location. You will also include a descriiption and a visual of the physiological functions of the particular organ system supported by appropriate citations.
Specifically, address the following critical elements:
Describe the anatomy of the primary organ system, ensuring that you:
Describe the organ system’s location by its anatomical position within the human body.
Describe the organs and structures contained in this organ system.
Identify key cell or tissue types contained in this organ system.
Provide a labeled diagram or image illustrating the organ system’s location relative to other organ systems.
Explain the physiology of the organ system, including:
A descriiption of the primary physiological functions of the organ system.
A labeled diagram or image illustrating one of the functions of the organ system.
Please look at the files I have attached. One is the rubric which will tell you what criteria to follow. The other attachment is an example of another organ assessment paper. Use it to give you an idea of how to write the assessment. I want you to write it just like that please. I also have access to turnitin.

For the second part of the assignment you will read the Methods and Results sect

For the second part of the assignment you will read the Methods and Results sections.
After reading both sections you will work backwards from the data in each figure or table. Your goal is to determine what experiment was performed. To do this, you will:
Diagram each experiment as a cartoon that shows the method used.
Annotate the figures with clarifying labels.
Write your own descriptive title for each cartoon and each figure in your own words.
Once again, the simplest way to submit this assignment may be to take pictures of your work with your mobile device or scan them into a PDF.
Key tips:
For each figure that you draw a cartoon for, depict what was physically done in each experiment. The point is to not show the results or restate the author’s description from the Results section.
Do not worry about your artistic ability. I am looking to see that you comprehend the key points of the experimental methods used in the paper, not to see how well you can draw.
Make sure that you describe your illustration and the original figure in YOUR OWN WORDS.
It’s okay if you don’t understand all of the methods. Do as much as you can and remember that this is to learn the process of taking a paper apart and analyzing it, not becoming an expert on this specific paper.
