Estimate how much the brain would swell due to osmosis if the concentration of the cerebrospinal fluid fell to 280mm. in other words, find what the new volume of the brain would be once equilibrium was reestablished. assume that (i) the cerebrospinal fluid is constantly replenished, so its solute concentration won't change; (ii) only water is passing across the cell membranes into brain cells (not solutes); and (iii) the volume of the brain is mostly water.

Blood ph and cerebrospinal fluid ph are affected by carbon dioxide content. how does this enable the organism to sense a disturbance in gas levels? question 2 options: a.the brain alters the ph of the cerebrospinal fluid to force the animal to retain more or less carbon dioxide b.the brain directly measures and monitors carbon dioxide and causes breathing changes accordingly c.the medulla oblongata is able to control the concentration of bicarbonate ions in the blood d.the medulla oblongata, which is in contact with cerebrospinal fluid, monitors ph and uses this measure to control breathing e.the lungs sense changes in oxygen concentration, which causes the medulla oblongata to speed up or slow breathing

100 points, brainliest, and free points if you answer all correctly1.use the diagram to answer the question.what would happen if some of the red blood cells were placed in beaker b? water would move into the cells by osmosis, causing the cells to shrink.water would move out of the cells by osmosis, causing the cells to shrink.water would move into the cells by osmosis, causing the cells to swell.water would move out of the cells by osmosis, causing the cells to swell2.use the diagram to answer the question.what would happen if some of the red blood cells were placed in beaker a? water would move into the cells by osmosis, and the cells would swell.water would move out of the cells by diffusion, and the cells would shrink.water would move out of the cells by osmosis, and the cells would shrink.water would move into the cells by diffusion, and the cells would swell.3.what would occur if some of the red blood cells were placed in beaker c? recall that red blood cells normally float in plasma.the concentration of water inside and outside the cells would be equal, so no osmosis would occur.the concentration of water inside and outside the cells would be equal, so no diffusion would occur.the concentration of water inside the cells would be less than outside, so the cells would swell.the concentration of water inside the cells would be greater than outside, so the cells would shrink.4.what is a function of water in a cell? producing lipids and carbohydratesassisting in the production of proteins the cell move and growpreventing rapid temperature changes5.the cell membrane and water are both involved in directing the cell’s activities and functionsthe movement of materials into and out of the cellpreventing chemical reactions from taking placemaking and packaging proteins for the cell6.the cell membrane and water are both involved in directing the cell’s activities and functionsthe movement of materials into and out of the cellpreventing chemical reactions from taking placemaking and packaging proteins for the cell7.which are types of passive transport? osmosis and diffusiondiffusion and engulfingtransport proteins and osmosisengulfing and transport proteins
