Below are the options given:
<em>A. NO CHANGE</em>
<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.
Margaret’s message to John II in her letter of 28 October 1470 was how was she going in the country, that she had sold some 'dysshes, plateres, and sawceres' and that she send the money to him. She advised him to take into account how he spent the money. She encouraged him to be brave. She said that she thanked God for how God guided his way, but that he must take care. And she finished her letter with the following phrase:
'God make here a good wooman' (hoping that God helped her and made of her a good person)
