紅血球的紅血蛋白的實驗

我5知我答得岩5岩啦

紅血球的紅血蛋白使哺乳類動物的血液呈紅色

係咪血紅素牙- -"?

放係離心機入面 出左黎 上面係淡黃 果d好似係血張

咁果個實驗

咁part a 我5明點解你話"為什麼試菅A內的鹽水" 5係蒸餾水咩=.=?

當佢係蒸餾水啦 咁蒸餾水既水勢係高過d血既 都因為紅血球係冇細胞壁, 當d水係咁入水 就會引致佢爆 入面d血紅素就出哂黎 所以紅色

而c 因為佢個水勢係低過d 血 所以冇影響

b 濃d既鹽水水勢比稀既低 所以就較為冇色- - (滲透作用)

c 你用xx 睇下紅血球既多少就知

Theory:
1) when the salt concentration inside a cell is higher than solution it suspends, an equilibrium will be attained so that water molecule will distribute equally, the rate of water enter the cell is greater than the rate water go out from the cell, thus water enter the cell and result in cell swelling, then bursting of the cell.

2) if the salt concentration inside a cell equal to the solution it suspends, there is only exchange in water molecule equally, thus rate of water going into the cell is equal to the rate of going out. So no swelling or shrinking of cell.
3) if the salt concentration inside a cell less than the solution it suspends, the rate of water going out the cell is greater than the rate of going in . So there is shrinking of cell.

To answer your question:
a) (explain by theory 1) swelling of red cells (紅血球) in blood, it results in swelling of red cells then 紅血球爆裂, 釋出hemoglobin(紅血蛋白), 導致紅色
b)試管的液體B(稀鹽水)的液體的鹽份較液體A(蒸餾水)多,但比紅血球少,故有部分紅血球爆裂, 釋出的hemoglobin(血紅蛋白或血紅素) 較液體A少,故所呈的紅色比試管A淺
c)離心機處理後, 把血細胞上面的液體 放在顥微鏡上觀看,同等容量的液體, 液體A之紅血球數量會比液體B少很多(可能接近零), 因大部分紅血球已爆裂.
