Hey if you can please help me with my homework. homework 6 is attached. let me know if you have any questions. thank you QUESTION 1Match the molecular component of the membrane with its role. One answer will be used twice. - A. B. C. D. Makes up the bulk of the lipid bilayer due to its amphipathic nature. - A. B. C. D. Only found on the outside of the plasma membrane, but not on any internal membranes. - A. B. C. D. Contributes to the lipid bilayer, but as a more minor component. It helps prevent the lipid bilayer from being too fluid. - A. B. C. D. This component enables the compartmentalization function of the membrane by separating one environment from another. - A. B. C. D. Needed for increasing membrane function to include signal transduction, adhesion, transport, and more.A.phospholipidB.oligosaccharides (in glycolipids or glycoproteins)C.cholesterolD.protein20 points QUESTION 2This question is about membrane structure and function. Carry out the matching using the best answer. Note that for the name of the function, alternative names are also given. Any of those could be used in conversation about how membranes work. Not all functions will be used. - A. B. C. D. E. F. G. The lipid bilayer creates a hydrophobic barrier between the outside world and the inside world of the cell. This could be said to provide this function of the membrane. - A. B. C. D. E. F. G. Some proteins are shaped like tubes or tunnels and span the entire thickness of the membrane to enable this function. - A. B. C. D. E. F. G. For some tissues to form, cells have to be able to form sheets together that hold together to create tissue barriers (like our skin). This function provided by the membranes of those cells is called this. - A. B. C. D. E. F. G. When one of our immune system cells encounters another one of our own cells, it should know not to attack. It should also know that it should attack if it encounters a foreign cell. This function of membranes is - A. B. C. D. E. F. G. A cell in the bone of a child encounters growth hormone and begins to divide. This is an example of this function.A.protectionB.shape (or structure)C.signal transduction (or recognize and respond, communicate, etc.)D.adhesion (or attachment, sticking, etc.)E.identification of self (or ID recognition)F.compartmentalization (which could also be called separation, isolation, etc.)G.transport (which could also be called selective permeability, letting some things in/out, etc.)15 points QUESTION 3Use this image that shows what is in higher concentration on each side of the membrane to answer these questions. That doesn't mean that these items are not also on the opposite side of the membrane... it is just that they are in higher concentration where shown. If you find this difficult to do, make sure to complete the transport activity provided in Module 3. That should help you learn this well, and this topic is essential for success in this class.For these first questions, just consider whether the concentration gradient is into or out of the cell. The concentration gradient on sodium ions (Na+) would be into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles. The concentration gradient on calcium ions (Ca2+) would be into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles. The concentration gradient on potassium ions (K+) would be into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles. The concentration gradient on carbon dioxide gas (CO2) would be into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles. The concentration gradient on chloride ions (Cl-) would be into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles. The concentration gradient on oxygen gas (O2) would be into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles. And the concentration gradient on lipid would be into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles while the concentration gradient on protein would be into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles.The concentration gradient is the driving force for into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles. (select diffusion or osmosis)For the next questions, you will need to select one of the following specific methods of transport:simple diffusionfacilitated diffusionosmosisactive transport using pumpsactive transport using vesicles (endocytosis and exocytosis)The drawing doesn't show any water, but if water were to cross this membrane it would cross by into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles.If sodium ions were to enter the cell, they would be crossing the membrane via into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles. If sodium ions were to exit the cell they would do so by into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles.If oxygen gas was to enter the cell, it would do so by into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles. If carbon dioxide gas was to exit the cell it would do so by into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles.If protein were to exit the cell, it would do so by into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles, while if lipid were to enter the cell it would do so by into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles.If potassium ions were to enter the cell they would do so by into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles. If potassium ions were to exit the cell they would do so by into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles.Finally, if calcium ions were to enter the cell they would do so by into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles. And if calcium ions were to exit the cell they would do so by into the cellout of the celldiffusionosmosissimple diffusionfacilitated diffusionactive transport using pumpsactive transport using vesicles.50 points QUESTION 4The fluidity of membranes lets them pinch and fuse. At any given time, a cell will have lots (hundreds or thousands) of little vesicles and some larger vesicles (called vacuoles) in them. Match the descriptions with the best term - A. B. C. D. E. Any time something large is brought into the cell, this term can be used to describe it. - A. B. C. D. E. When a cell transports really large, undissolved materials into it, that is typically called this. - A. B. C. D. E. When a cell secretes materials like hormones or sweat in vesicles, it uses this. - A. B. C. D. E. When a cell brings in large materials (like starch) that are dissolved so that they are not visible even in the electron microscope, that is considered this. - A. B. C. D. E. Any time any cell transports something too large to fit through a protein transporter, whether it brings that item into the cell or kicks that item out of the cell, it has to use this method.A.endocytosisB.pinocytosisC.phagocytosisD.exocytosisE.active transport using vesicles

Unit 2: Plate Tectonics and Continental DriftPart AScientists predict that Africa is going to smash into Europe as Australia migrates north to merge with Asia. Meanwhile the Atlantic Ocean will probably widen for a spell before it reverses course and later disappears. View this link https://science.nasa.gov/science-news/science-at-nasa/2000/ast06oct_1 (Links to an external site.) for information related to the above statement, then research additional information about present plate motion to predict future continental positions. Using the information that you find, discuss the landmass formation that will occur if they have predicted correctly. What significant change may occur if this would happen? What changes would occur if this were to happen quickly in today's world?Part B"Two hundred and fifty million years ago the land masses of Earth were clustered into one supercontinent dubbed Pangea. As Yogi Berra might say, it looks like "deja vu all over again" as the present-day continents slowly converge during the next 250 million years to form another mega-continent: Pangea Ultima". Use this link https://dinosaurpictures.org/ancient-earth#470 (Links to an external site.) to see what Earth looked like where you live today. In the top left corner submit the name of your city, state, and country and review what Earth looked like many years ago. Share with your classmates what Earth looked like from your location. In the upper right hand corner you can also research the different events that took place over thousands of years past. What did the continents look like during the Juriassic Period?
