    How was paper went of BIOLOGY 5090/22

    The main thing that moves water up a stem is a transpirational pull. Transpiration pull is produced when the sun evaporates the water from mesophyll, causing a water to move from xylem into other mesophyll cells. This creates a suction force which pulls water up the plant.

    The total volume for each Drink was 1.5 dm^3. You take 1.5 dm^3 of A. You lose 90% of it. You take 1.5 dm^3 of B. You lose 80% of it. You take 1.5 dm^3 of C. You lose 65-70% of it. Clearly Drink C loses less water so why would you avoid it. I dont care about what the doctors say. When the graph...

    There is no relation to water content. You're taking the same , 1.5 dm^3 of the liquids. If you saw the graph, which i dont think you did, C retains the most water, like you take in 1.5 and only around 0.8 was urinated out while for A almost all of it was urinated out.

    2 and 4 occur through the cell membrane but the the cell membrane does not control them. In 1, active transport across the cell surface membrane actually uses energy to get the ions etc.

    20- Your body is cooling down. You need a response to heat it. Shivering is actually contraction of muscles which produces heat. Thus IT IS reversing the effect. 30- Most of the amino acid are actually used by the body for making protoplasm, enzymes etc. So the amount of protein is more than the...
