The writer wants to introduce the topic of electronegativity with a concrete, casually observable example from the natural world. Which choice best accomplishes this goal

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:

A. NO CHANGE

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

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

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

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:

Electronegativity is a measure of the affinity between electrons and atoms.  

When an atom exhibits greater attraction for electrons, it is said to have very high electronegativity.

Electronegativity is an inherent quality that remains constant in all the atoms of an element. Fluorine is the chemical element with the highest electronegativity.  

In nature, the most important element which whose electronegative qualities (or whose ability to bind with other atoms) make it crucial for life is Oxygen.

When we inhale air, the Oxygen is used by our bodies to convert glucose to energy and Carbon Di-Oxide is released.

As the World Wildlife Foundation reports on its website, "Pirate fishing accounts for an estimated 20%
of the world's catch and as much as 50% in some fisheries. The costs of illegal fishing are significant,
with the value of pirate fish products estimated at between $10-$23.5 billion annually."

Read the excerpt from chapter 6 of The Travels of Marco Polo. This, then, I would have you know, is how they are made. They are built of the wood called spruce and of fir. They have one deck; and above this deck, in most ships, are at least sixty cabins, each of which can comfortably accommodate one merchant. They have one steering-oar and four masts. Often they add another two masts, which are hoisted and lowered at pleasure. The entire hull is of double thickness: that is to say, one plank is fastened over the top of another, and this double planking extends all the way round. It is caulked outside and in, and the fastening is done with iron nails. What is the author's purpose for writing this text? to entertain readers by describing travels on a ship to inform readers about how ships are built to persuade readers that they should build ships to educate readers about how they can build their own ships

Which excerpt is a counterclaim in "What to the Slave is the Fourth of July?” What is this but the acknowledgment that the slave is a moral, intellectual, and responsible being? The manhood of the slave is conceded. There are seventy-two crimes in the State of Virginia which, if committed by a black man (no matter how ignorant he be), subject him to the punishment of death; while only two of the same crimes will subject a white man to the like punishment. It is admitted in the fact that Southern statute books are covered with enactments forbidding, under severe fines and penalties, the teaching of the slave to read or to write. What, then, remains to be argued? Is it that slavery is not divine; that God did not establish it; that our doctors of divinity are mistaken?

Read the excerpt from “Tools of the Spymaster."

The numbers that Major Tallmadge assigned to members of the Culper Ring were from a secret writing system he invented. He substituted digits for words that would be used in messages. "Long Island," for example, was 728, "arms" was 7, and "city" was 88. There was a number for each month, such as 341 for "January." He made four copies of his codes. He kept one and gave the others to Woodhull, Townsend, and General Washington. For words that did not have a number code, Tallmadge gave his agents a cipher. In a cipher, each letter in a message is replaced by another letter or a number.

Which statement is best supported by text evidence from the excerpt?

All members of the Culper Ring received a copy of Tallmadge’s code.
A cipher was a common instrument used during the American Revolution.
Words that did not have a number code could not be used in secret messages.
General Washington could read messages written in Tallmadge’s code.

Which words in this excerpt from Washington Irving's "The Legend of Sleepy Hollow" indicate that it is a work of gothic literature? It [the tree] was connected with the tragical story of the unfortunate André, who had been taken prisoner hard by; and was universally known by the name of Major André's tree. The common people regarded it with a mixture of respect and superstition, partly out of sympathy for the fate of its ill-starred namesake, and partly from the tales of strange sights and doleful lamentations told concerning it. As Ichabod approached this fearful tree, he began to whistle; he thought his whistle was answered–it was but a blast sweeping sharply through the dry branches.

Which two details best reveal the woman's character?
The Story of an Hour
by Kate Chopin (adapted excerpt)
She could see in the open square before her house the tops of trees that were all aquiver with the new spring life. The delicious breath of rain
was in the air. In the street below a peddler was crying his wares, the notes of a distant song which some one was singing reached her faintly,
and countless sparrows were twittering in the eaves.
She sat with her head thrown back upon the cushion of the chair, quite motionless, except when a sob came up into her throat and shook her,
as a child who has cried itself to sleep continues to sob in its dreams.
She was young, with a fair, calm face, whose lines bespoke repression and even a certain strength, but now there was a dull stare in her eyes,
whose gaze was fixed away off yonder. It was not a glance of reflection, but rather indicated a suspension of intelligent thought.
There was something coming to her and she was waiting for it, fearfully. What was it? She did not know; it was too subtle and elusive to name;
but she felt it, creeping out of the sky, reaching toward her through the sounds, the scents, the color that filled the air.
She was beginning to recognize this thing that was approaching to possess her and she was stri
