What does Lady Macbeth mean when she says: "to beguile the time, look like the time, bear welcome in your eye, your hand, your tongue: look like...

Lady Macbeth utters these words in Act 1, Scene 5. This is
the scene in which she counsels her husband, Macbeth, on how he should behave when they
welcome king Duncan and his crew. What she specifically wants Macbeth to do is to come
across as a pleasant and welcoming host when the King arrives because doing so will not
reveal Macbeth's true intention, which is to kill the King and take the
throne.

Now, let us take a look at the quote, so that we
can examine the words more closely:

 Your face, my thane, is as a book where
men
 May read strange matters. To beguile the time,
 Look like the
time; bear welcome in your eye,
 Your hand, your tongue: look like the
innocent flower,
 But be the serpent
under't.

By saying that
Macbeth's face is like "a book where men may read strange matters," Lady Macbeth implies
that the King and his company may be able to discern Macbeth's real thoughts. Therefore,
she advises him to "look like the time" if he is to "beguile the time." What this means
is -- Lady Macbeth suggests that her husband must demonstrate the ability to conduct
himself as others expect him to despite his "black and deep desires." He must appear
"like the innocent flower," ready to protect his King and be his loyal subject.

This scene is very significant because it marks the
beginning of Macbeth's unscrupulousness and tyranny. Once he kills the King, he becomes
eager to kill anyone who could potentially stand in his way.

What are some similes used by Scout in To Kill a Mockingbird and to what do they refer?Harper Lee's To Kill a Mockingbird

In describing the sick, addicted, and dying Mrs. Dubose,
to whom Jem has been given the assignment by Atticus of reading each afternoon, Scout
employs original similes, to say the least:

She was horrible.  Her face was the color of a
dirty pillowcase, and the corner of her mouth glistened with wet, which inched
like a glacier down the deep grooves enclosing her
chin.

 notices
that Mrs. Dubose's corrections of Jem have become fewer and fewer.  And, something has
happened, for only her head and shoulders are visible above her covers.  As her head
moves from side to side, Scout sees saliva collecting on her
lips:

Her
mouth seemed to have a private existence of its own.  It worked separate and apart from
the rest of her, out and in, like a clam hole at low
tide.

Occasionally it would say, "Pt,"
like some viscous substance coming to a
boil.

How does Aunt Alexandra react to her brother's defeat? What does it show you about her? (Chapter 22)

Atticus' defeat gives us all an opportunity to understand Alexandra as more than the strict aunt who is absorbed with her family's social standing and with Scout growing up to be a proper lady. She shows empathy, compassion, and respect for her brother; in fact, she calls him "brother," something she doesn't do often. She shows concern for Jem's worry and sorrow over the defeat, asking if he is alright. Later, at the tea party with her mission group, Alexandra, we learn seems to see through their hypocrisy every bit as much as the narrator, Scout.

Who discovered the first anti-biotic and what was it?

The first antibacterial substance that can be considered
as a limited-spectrum antibiotic was Salvarsan and it was
discovered in 1910, by the German physician and chemist Paul Ehrlich (1854-1915).
Salvarsan was a medicine meant to cure syphilis, which was very prevalent at that
time.

Salvarsan was followed, in 1928, by the epochal
discovery of Penicillin, by Alexander
Fleming, who noted that secretion of green mold "Penicillium notatum
(Penicillium chrysogenum) destroys bacteria colony from the
laboratory.

Another finding which is worth mentioning is
the discovery in 1935 of sulphonamides, by Gerhard Domagk, who is not an antibiotic,
being not bactericidal but only bacteriostatic.  It follows the discovery of a series of
antibiotics as streptomycin, tetracycline, etc.

Why does Piggy conclude that no one will know where they are?

Early in the first chapter of Lord of the
Flies, Ralph seems unconcerned about being rescued since he has so much faith
in his father, who is a commander in the British navy. "When he gets leave, he'll come
here and rescue us," Ralph tells Piggy. But Piggy is more
realistic.

"How does he know we're
here?"
Because, thought Ralph, because, because...
"They'd tell him
at the airport."
Piggy shook his head...
"Not them. Didn't you hear
what the pilot said? About the atom bomb. They're all dead...
"They're all
dead," said Piggy, "an' this is an island. Nobody don't know we're here. Your dad don't
know. Nobody don't know--
"We may stay here till we
die."

Piggy is under the
misapprehension that the atom bomb has killed many (if not all) of the British troops
and sailors. Despite this misunderstanding--and his bad grammar--he is aware that no one
could possibly know the boys have survived and are stranded on the island. He expects to
be there a long time.

What is Carlos' epiphany at the end of "The Doll Queen"?

Carlos Fuentes writes "The Doll Queen" in magical realism
as a symbolist short story of the grotesque literature genre. Magical realism is a Latin
American originated style movement that features a blurring between the boundaries of
reality and fantasy: what seems like a realistic story in a realistic setting and time,
with realistic characters will suddenly take on qualities attributed to magic, folk
lore, and/or legend. This blending of of realism and magicalism is seen in "The Doll
Queen" when Amilamia suddenly appears as a disfigured individual confined to a
wheelchair while her child-sized coffin is on display in the other
room.

The ultimate meaning of "The Doll Queen" is that
cutting one's self off from one's past, or more specifically for Carlos the hero, from
his primitive, intuitive, emotional, Indian past leaves one stunted and dwindled in
development, misshapen, and grotesque. It is the ancient side of self that can provide
one's name, and only Amilamia gives the narrator a name, a name that is rejected just as
she is rejected as the narrator runs away. Cutting one's self off from one's past cuts
one off from one's self as well.

What are the three omens in Chapter 6 of The Pigman? What does Lorraine think they mean?

The three omens that Lorraine thinks she sees at the zoo
are the lady selling peanuts, the peacock, and the kid sitting outside the vampire bat
exhibit. She thinks the omens are saying that bad things are going to happen as a result
of their involvement with the Pigman.

The first omen is a
woman selling peanuts. Lorraine goes up to her and asks for four bags. The lady is very
rude and antagonistic - Lorraine says, "You could tell she hated kids - just hated
them." To Lorraine, that is the first omen, and she wishes she and John had "left right
on the spot."

The second omen is when she is "attacked" by
a peacock. A large white peacock opens up its feathers and starts dancing in front of
her when she opens her first bag of peanuts. Frightened, Lorraine backs up against a
fence, and she is not reassured when the Pigman just grins and tells her, "Just offer it
a peanut...He likes you. Ha, ha."

The third omen occurs in
the nocturnal room of the Mammal Building. Lorraine "almost (goes) into shock" when she
gets a good look at the vampire bats, who are shown with accompanying pictures of a
couple of them "sucking the blood out of a horse's neck." The creepiest part about the
exhibit, for Lorraine, however, the part that she considers to be an omen, is a child
that is sitting in front of the bat cage. The little boy isn't looking at the bats; he
is "looking at you when you (come) to look at the bats," smirking.
The kid makes Lorraine feel uneasy, as if she is a bat in the cage and he is on the
outside looking at her (Chapter 6).
