Explanation:
A revision is when a given sentence or any given passage is rewritten in a better form. This can involve changes in the words, or voice or tense, or even the structure of the whole sentence.
In the given sentence, the proper noun is used after the pronoun. Instead of using the pronoun to start the sentence, if we use the proper noun "Anna" to start the sentence, then the sentence is made easier to understand and also who is being talked about. Also, changing the structure of the sentence by rearranging certain words will make the sentence better in form and construction.
Thus, the revised sentence will be option C.
Answer:
a synonym is a word or phrase that means exactly or nearly the same as another word or phrase
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.
