This image is a model that shows 3 different sized cells. The yellow area of each square is the part of the cell where oxygen is able to easily get to through the cell membrane. Use specific information from this diagram to explain why even large organisms (like humans) are made out of many smaller cells.

If I do a car, airplane, ship or spaceship type analogy, I could say that the propulsion system is like the mitochondria since in both cases this is usually the only source of power for the vehicle. Although the relationship is kind of obvious, there may be a trick to it. You may have an electric car that has no engine. In this case, the battery or batteries would represent the mitochondrion or mitochondria.
The movement of molecules in and out of a cell is essential to its function. The cell membrane regulates this movement though processes such as diffusion, osmosis, active transport, etc. These activities on the next couple pages are designed to assess your understanding of these processes. Scenario #3 Semi-permeable membrane Охудen Carbon Dioxide Lungs I Blood stream After studying the image above, select the statement(s) that would explain what is likely to happen. Choose ALL that apply. O The carbon dioxide molecules will move into the lungs until equalibrium is reached. O All the carbon dioxide molecules will move into the lungs to be exhaled. O All the oxygen molecules will move from the lungs into the blood stream. O The semipermeable membrane will prevent the movement of either molecule. O The oxygen molecules will move into the blood stream until equalibrium is reached.

Which of the following statements is correct? a. Ribosomes are only found in bacteria and archaea. b. Some animal cells are prokaryotic c. Only eukaryotic cells have mitochondria d. The plasma membrane is the outermost boundary of all cells. e. Some cell membranes do not consists of lipids.
Organelles and Cystic Fibrosis A plasma membrane transport protein called CFTR moves chloride ions out of cells lining cavities and ducts of the lungs, liver, pancreas, intestines, and reproductive system. Water that follows the ions creates a thin film that allows mucus to slide easily through these structures. People with cystic fibrosis (CF) have too few copies of the CFTR protein in the plasma membranes of their cells. Not enough chloride ions leave the cells, and so not enough water leaves them either. The result is thick, dry mucus that clogs the airways to the lungs and other passages. Symptoms include difficulty breathing and chronic lung infections. In 2000, researchers tracked the cellular location of the CFTR protein as it was being produced in cells from people with CF (Figure 3.13). Figure 3.13 Cellular location of the CFTR protein. Graph compares the amounts of CFTR protein found in endoplasmic reticulum, vesicles traveling from ER to Golgi, and Golgi bodies in CF cells and normal cells. In which organelle is the amount of CFTR protein most similar in both types of cells?

You have genetically modified a cell to have a thicker membrane than normal (25nm). To keepyour cells alive, you need to understand how diffusion of nutrients works. What is the flux ofglucose through the cell membrane given that: -The concentration of glucose in the media is 10mM -The concentration of glucose inside the cell is 2mM -The diffusivity of glucose is 6x10-10m2/s
There are 4 basic tissues in the human body. For each of the following organs/structures describe the location and function of at least three basic tissues found in them. Heart and stomach You have received GHS 1 million as a scientist to develop a vaccine for corona virus. You have been able to develop the vaccine but now the challenge is how the vaccine will enter the cells of the body when you inject it. From your knowledge of the structure of the cell membrane give and explain 2 features you can exploit in order for the vaccine to go across the cell membrane into the cell.
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
Draw to scale the outline of two spherical cells, one a bacterium with a diameter of 1 μm, the other an animal cell with a diameter of 15 μm. Calculate the volume, surface area, and surface-to-volume ratio for each cell. how would the latter ratio change if you included the internal membranes of the cell in the calculation of surface area (assume internal membranes have 15 times the area of the plasma membrane)? (the volume of a sphere is given by 4πr3/3 and its surface by 4πr2, where r is its radius.) discuss the following hypothesis: “internal membranes allowed bigger cells to evolve.”
