<em>B. How do water striders skim across the surfaces of ponds and lakes? Their hydrophobic legs are uniquely suited to this process, but the insects</em>
<em>C. How do our bodies break down the food we consume every day? While digestion would be impossible without enzymes and other proteins, these molecules</em>
<em>D. How does our DNA maintain a double helical structure? While the shape of this nucleic acid is the result of many complex properties, its structures</em>
Option B is correct because it gives a concrete, casually observable example from the natural world and thereby accomplishes the goal. It explains the connection between surface tension and electronegativity.
Option B gives an example from the natural world - the water strider.
The water striders are a good example of insects that use the high surface tension of water and long, hydrophobic legs. This enables them to walk on water. Their legs are coated with a hydrophobic substance. The hydrophobic substance makes the legs to repel water molecules i.e it makes water unable to stick to their legs. This makes them to easily skim on water surfaces.

Answer:
Dear ___,
It's been around 8 months or so since the coronavirus became a present issue. I thought I was just getting an extra week of spring break but it turned into a quarantine. At the start, it was difficult because when you went to the grocery stores they were always out of toilet paper and hand sanitizer. Canned food was always missing from the shelves. Oh yeah, we also had no school now. Well, in-person school at least. We now learn online and have google meets or zoom calls. It's very frustrating with my bad internet. Its pretty weird having to wear a mask everywhere now I don't really like it. The corona has really affected my life because sports are being affected everywhere. I hope that we find a cure soon.
