A. Consider a large, cubic cell that measures 100 micrometers on a side. What is its surface area/volume ratio? B. Assume that a cell requires a surface area/volume ratio of at least 1 to survive. Would dividing this cell into 125 cells that together had a volume of 1,000,000 micrometer 3 ensure survival? C. Why is having a high surface area to volume ratio so important for cell survival?

? H Identify the cell A Name one function of this cell.

II. CELL FEATURE OBSERVATION The following questions pertains to the features of cells. Provide the answers to each of the questions. Maximum of 5 sentences is allowed per question. 1. Cell features a. What limits a size of the cell and why? b. Describe the relationship of between cell shape and function. Give example of a cell influencing function. c. Why is cell differentiation important?

In a monolayer of cultured epithelial cells, the cells may or may not have formed tight junctions. What experimental test could be used to determine it the cells have functional tight junction structures? Place a small dye (1 k Da in molecular weight) into the culture media of cells cultured on a glass coverslip and use live imaging to monitor whether the dye can penetrate into the O cytoplasm of the cells, as would be expected if the cells have functional tight junctions. Inject a cell with a small dye (<1 kDa in molecular weight) and use live cell imaging to track whether the dye moves into neighboring cells, as would be expected if the cells have functional O tight junctions.

When the new cell matures, it will be approximately how manytimes greater in volume and how many times greater in surfacearea than its current size?

1 2. Type here to search T Required The diagram below represents a cell. Carbon dioxide (CO₂) and oxygen (O₂) molecules can move freely across the cell membrane by diffusion. Some molecules CO₂ CO₂ CO₂ O 0₂ 02 O2 CO2 0₂ Based on the number of CO₂ and O₂ molecules both inside and outside the cell, what would most likely happen after a period of time? The concentration of O₂ will increase inside the cell. The concentration of O₂ will remain the same outside the cell. The concentration of CO₂ will remain the same inside the cell. The concentration of CO₂ will decrease outside the cell. DELL E @ J 3:56 P 9/15/2022

how owuld you write a resopnce for this statment below? Any questions?   A normal CFTR protein is called an ion chain in which moves atoms and molecules in and out of the cell.  The CFTR ion chain is moving chloride ions in the same manner when pertaining to the lungs.  When these chloride ions are outside of the cell they then attract water which enables the cilia to move back and forth.  This process is very important because this is how the body discards of bacteria, mucus, and germs from the airways.  In instances where the CFTR gene has mutations, the chloride ions are not properly moved to the outside of the cell.  When this happens the mucus in the lung is then dehydrated due to the lack of attraction of water and not discarded as needed.  This then makes it hard for the person to breathe because the mucus is not being cleared from the airways.  In addition, the person is also susceptible to infection due to the lack of purging of germs and bacteria (Basics of the CFTR Protein,…

a. What type of cell is shown? (the large one at the center of the image) b. How do you know what type of cell this is? c. Identify the structure the arrow. d. What does the appearance of the structure at the arrow mean? (In other words, what does it tell us the cell can do?)

i. Why are carbon, nitrogen, oxygen, and hydrogen the most abundant elements in living matter and, therefore, considered macronutrients? ii. Explain the Fluid Mosaic membrane model of plasma membrane structure. iii. What is the difference between simple diffusion, facilitated diffusion, and active transport? :=
