How does our body lower our blood sugar level?
我们的身体如何降低血糖水平？
Release insulin so our cell can take in glucose from the blood.

Why are the heads of the phospholipids facing outside the cell, but the tails are facing inside?
为什么磷脂的头部朝向细胞外部，而尾部朝向内部
Head= hydrophilic=love water
Tail=hydrophobic=hate water
“头部 = 亲水 = 喜水
尾部 = 疏水 = 恶水（怕水）”

If the solute to water ratio of a radish is 5:2 and the solute to water ratio of the surrounding water is 3:2, where would the water flow?
如果萝卜的溶质与水比例是5:2，而周围水的溶质与水比例是3:2，那么
Water always go to an area of high solute to water ratio so the water will go into the raddish.
水总是流向溶质比例更高的地方，所以它会进入萝卜里。
On a real note, how much do you think Mr. Zheng appreciate you all?
说句实在的，你们觉得郑老师有多欣赏你们？
