Exercise 2 Exploring Cell Size In this exercise, you will examine the effect changes in cell size have on the surface area to volume ratio (SAV) of a cell, and how this affects diffusion of molecules into the cell. You will be specifically examining the diffusion of water molecules through the cell as water is crucial to the majority of cellular activities. A water molecule will passively diffuse through the cytoplasm at an approximate rate of 200 um/s. A human skin cell has an average diameter of 30 pm. This means a water molecule can diffuse from the cell membrane to the center of the cell in approximately 0.075 seconds. Procedure Launch the virtual cell size exercise below. 2 Manipulate the dial to adjust the diameter of the cell. 1 150 pm Distance Traveled in 0.075 seconds 90 pm 210 μm 30 pm 270 pm Diameter (um) 30 0.075 Time to center of the cell(s) Procedure 1 Launch the virtual cell size exercise below. 2 Manipulate the dial to adjust the diameter of the cell. 150 pm Distance Traveled in 0.075 seconds 90 pm 210 pm 30 pm 270 pm Diameter (um) 30 Time to center of the cell (s) 0.075 3 Examine the effect changes in size have on how long it will take for a water molecule to passively diffuse to the center of the cell from the cell membrane. Complete Data Table 1 as you work through the exercise, using Equation 1 and Equation 2.

You will also go through the above steps to create a personal write-up for a different article in
the list above. This write-up will also be worth 20 pts that will be ineligible for dropped points.
Personal write-ups should be typed and should answer all pertinent information discussed
above. Write-ups should be at least 2 pages in length and can take a paragraph or question and
answer format, as long as all of the questions listed above are addressed. Writing tone should
be professional and scientific and the write-up should faithfully and thoroughly answer the
questions listed in this packet. Grading will be based on how well these criteria are met.
the questions are in the attached pdf and all QUESTIONS need to be answered on the personal write-up paper.
I’ve attached the paper that I want a write-up on as well

This is one research paper that is suggested to read before starting the project

This is one research paper that is suggested to read before starting the project: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3145266/#R7
This is an video example of the project made by a student in the past, you should stick to this example, thank you.
https://kapwi.ng/w/0zqbHp3UH6
Try to include charts, pictures, examples and a lot of biological reasoning to back up the arguments because this is a Biology class.
This class is about Evolutionary Biology so the project should focus on that, the guideline is below.
Grading of Final Project Presentation: What needs to be included in your presentation:
• Your audience is your biology major peers
• The presentation should be 9-10 min.
• You need to include
1) background information,
2) questions that are addressed,
3) how scientists went about testing,
4) what they found, and
5) the future directions for this research.
• Your presentation also must include the following contents:
o Genes: You need to research into the chromosome this gene resides on, type of mutation cause the trait, mode of inheritance, etc.
o Traits: What traits/disorders this mutation can cause and how do they impact the organisms?
o Evolution: Tell us an evolutionary story about this trait
o At least ONE Research Paper from primary sources to support the idea (and not just from the websites)

For each of the following cranial bones: Frontal Parietal Occipital Temporal -N

For each of the following cranial bones:
Frontal
Parietal
Occipital
Temporal
-Name the sutures that forms their borders (i.e. the medial border of the parietal bone is the sagittal suture).
-Name the major parts of each bone (i.e. the temporal bone has two main parts: petrous and squamous).
-List the functions of each bone (i.e. the temporal bone forms the temple, ear canal, and the TMJ, anchors neck muscles, and protects vessels that circulate blood in the brain).
-Describe how each bone articulates with other bones to form joints, the orbit, the cranial floor, and the zygomatic arch
