    1)

    A python can survive by eating a large meal once or twice a year.

    When it does eat,

    microvilli in its small intestine lengthen fourfold

    and its stomach pH drops from 7 to 1.

    Explain the benefits of these changes.

    蟒蛇可以靠每年只吃一次或兩次大餐,就可以活存下來。

    當它大吃一頓的時候,

    其小腸內的絨毛會延長四倍,

    胃內的 pH值 會由 7 降至 1。

    解釋這些變化的好處。

    當小腸內的絨毛延長四倍,

    小腸(細胞)表面和食物接觸的面積,也會增加數倍,

    有助於食物的消化吸收。

    胃內的 pH值 由 7 中性,降至 1 酸性,

    即分泌胃酸有助於食物的分解。

    2)

    a)

    Which item was highest in fat ?
