How do hydrogen bonds affect water?
The presence of hydrogen bonds also makes water molecules more ‘sticky’ or in scientific terms cohesive and adhesive. The small charges on the water molecules allows them to stick together which is why water has a ‘skin’ that small insects can walk on, and also explains why water can be sucked up a straw so easily.
Why is it important that hydrogen bonds are weak?
Weak bonds may be easily broken but they are very important because they help to determine and stabilize the shapes of biological molecules. For example, they are important in stabilizing the secondary structure (alpha helix and beta-pleated sheet) of proteins. Hydrogen bonds keep complementary strands of DNA together.
How do I protect my plants from hard freeze?
Wet soil holds heat better than dry soil, protecting roots and warming air near the soil. Bed sheets, drop cloths, blankets and plastic sheets make suitable covers for vulnerable plants.
