Answer:
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
Explanation:
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.

Explanation:
Read the excerpt from A Black Hole is NOT a Hole.
Any and all events on the Sun remain invisible to you for as long as it is below the horizon. If the Sun suddenly turned purple, you wouldn’t see it happen.
In a similar way, once an object enters the extreme gravity zone of a black hole, the object disappears from view.
Which word signals that a comparison is being made?
extreme
object
gravity
similar
