Q.1. Many aquatic invertebrates, like fishing spiders and water striders, can walk on surface of water. How are they able to do this and why can't we?

2. The shape of a protein is frequently very important to how it works. For example, on the surface of some human immune system cells is a type of protein called an HLA? HLAs help the immune system recognize foreign invaders (cells and particles from outside the body) by binding to them using a tiny pair of molecular 'jaws'. What do you think would happen if a person had a mutation that prevented the jaw part of their HLA molecules from becoming the correct shape?
