Can plants survive in salt water?

While most plants cannot survive in salt water, there are
plants that can.

One example of a type of plant that can
survive in salt water is something called a marine seagrass.  I have attached a link
here to a page that talks in depth about this kind of
plant.

Another example of a plant that grows in salt water
is the mangrove.  Mangroves grow along the coasts of many tropical places, including the
island where I grew up.  Their roots go down into the floor of the ocean right along
shore.  The "wettropics.gov" site I have linked to gives more information about these
plants.

In general, though, plants cannot live in salt
water because they do not have genes that allow them to tolerate salt.  Mangroves and
marine seagrasses do have such genes.

What is the theme, language, and style/structure of "Oh, Oh, You Will Be Sorry" by Edna St Vincent Millay?What is the theme (insights about life in...

I am allowed to answer only one of your questions: the
parts must each be listed as separate questions.

Edna St.
Vincent Millay was a feminist and activist for women's rights during the beginning of
the twentieth century. This can easily be seen in her
poem.

In terms of the theme, the poem "Oh, Oh, You Will Be
Sorry" is about the cultural and intellectual repression of women. The speaker has
obviously tried to have an rational, "educated" conversation with her husband, and he
has discredited her ability to handle a discussion of consequence by saying, "What a big
book for such a little head!"

The title would indicate that
her husband has misspoken, and the wife (the narrator) is highly offended; she promises
that she will never again try to engage him in any kind of "scholarly" debate. She will
not read in front of him, but will behave herself like men expect their women to act
during this time period: she will offer him a kiss, or a look at look at her newest hat.
She will love him and be "sweet and soft," but their relationship will not be the same
from this moment on.

This wife informs her husband that one
day he will knock and enter her room, but she will be gone, and he can just whistle for
her, for she will have no time for
him.

The theme here is about a woman being a man's equal in
terms of "brain function." This was not a popular concept during this era. On one hand,
women were a force to be reckoned with in terms of helping the poor, and supporting the
church and morals within society and the home. At the same time, they were also trying
to earn the right to vote, and it was a long, hard battle. Millay is not only expressing
her belief that men and women were equals, but offering words of warning to men who were
unable to see this or accept it.

In today's society, these
messages will be lost in that opportunities are available to women today that could not
have been imagined a hundred years ago. While it is said that women generally only earn
seventy percent of what men make for the same job, women are no longer relegated to
inferior jobs because of gender, and can seek education and employment just as men
do.

In "Winter Dreams", what feelings does Dexter associate with each season?

It is clear from the title of this excellent short story
by Fitzgerald that the seasons, or at least winter, will have a serious role in the
action. It is in the opening paragraphs that we are given a description of how the
seasons impact Dexter and which seasons are more important to him. Note how the changing
of seasons changes Dexter:

readability="10">

Dexter knew that there was something dismal
about this Northern spring, just as he knew there was something gorgeous about the fall.
Fall made him clinch his hands and tremble and repeat idiotic sentences to himself, and
make brisk abrupt gestures of command to imaginary audiences and armies. October filled
him with hope with November raised to a sort of ecstatic
triumph...

It is clear then
that fall, with the hope of the approaching winter, makes Dexter feel more than he is -
it makes him feel that he is an important man of value and commanding respect and
loyalty from "imaginary audiences." It is no wonder then that because of this affinity
he has with winter that he chooses to attach his "dreams" to this season - cold and
elusive as they will turn out to be.

Describe the device invented by Faber. How will Montag use it?

I assume that you are referring to the device that Faber
gives Montag to put in his ear.

The device (referred to as
"the bullet") is about the size and shape of a .22 caliber bullet.  It fits in the ear
and people will not necessarily know it's there.  It is a two-way communications
device.  Faber presumably has some sort of device in his house that communicates with
the bullet.  It lets him speak to Montag and it lets him hear whatever is going on
around Montag.

Montag is going to use the device to help
subvert the society he lives in.  Faber will, for example, tell him what to say to
people.  He will also talk to Montag to help him understand and resist things that
Beatty says to him (that are meant to force Montag to conform).  So Faber will kind of
talk Montag through his days, helping him to try to make people doubt the society they
live in.

Compare suspense techniques in Edgar Poe's 'Tell-Tale Heart', and Alfred Hitchcocks film 'Psycho'. How would you explain similar techniques

I think that both texts make use of the ordinary and the
possible building to the bizarre and unusual in terms of suspense techniques. Each text
has a lead up to the murder in ordinary domestic circumstances that are capitalized on
by the killers. Each text takes a basic area of vulnerability the reader could
experience and then extends that fear to a terrifying
conclusion.

 The narrator in The Tell Tale
Heart tells us he is mad when reflecting on the events of the story, but we
can believe that his behaviour towards his victim would have appeared normal in the lead
up to the crime. He tells us that he liked the old man, but his calm observation of the
old man with the ‘vulture eye’ becomes a sinister possibility that could have involved
many of the readership of the time. Being observed whilst asleep is a latent fear that
many readers could have.

 Similarly, Norman Bates appears
calm and gentle, if a little diffident. His entry into the motel room and his stabbing
of Marion is a credible, if unpleasant, scene.  As with Poe’s story, the shock of the
shower scene is its credibility given the characters involved. The violation of privacy
that Marion experiences is another latent fear – the stabbing just compounds the
terror.

Ismail & Rashad have $3.85 each person has only one type of coin. Rashad had 7 more.how many coins,and which kind could each person have?Have to...

As each of them has coins of only one type let it be worth
x dollars. Let the total number of coins be N.

Now the
total value of the coins is $3.85 or N*x= 3.85

Rashad has 7
coins more than Ismail. So if Rashad has n coins Ismail has n-7. The sum of n and n-7 is
N

So now we get 2n-7=N

Also
(2n-7)*x = 3.85

Now in the expression lets substitute
different values for n and x. We can only take those solutions as valid that yield a
whole number for n.

If x= .01 , 2n-7 = 385 => n=
(385 - 7)/2 = 189.

So the Rashad has 196
coins and Ismail has 189 coins of 0.01
each.

If x=0.05 , 2n-7 = 77 => n= (77
- 7)/2 = 35.

So Rashad has 42 coins and
Ismail has 35 coins of 0.05 each.

If x= 0.35
, 2n-7 = 11 => n= (11 - 7)/2 = 2.

So
Rashad has 9 coins and Ismail has 2 coins of 0.35
each.

If x= 0.07 , 2n-7 = 55 => n=
(55 - 7)/2 = 24.

So Rashad has 31 coins and
Ismail has 24 coins of 0.07 each.

What is the difference between average cost and marginal cost?

Average cost of a commodity is simply the total cost of
production of n units divided by the number of units, i.e. 'n'. In other words, it is
the cost of production of one unit.

Marginal cost of a
commodity is the cost of production of an incremental
unit. 

Average cost is also defined as the sum of average
fixed cost and average variable cost.

If fixed cost is
represented as FC, variable cost as VC, total cost as TC and the number of quantities
produced as Q,

then average cost, AC = TC/Q =
(FC+VC)/Q

whereas, Marginal cost, MC = change in VC/change
in Q (or incremental cost)

For example, if 4 phones are
produced at a cost of $100 and 5 phones are produced at
$130,

then average cost = $100/4 =
$25

and marginal cost = $130-$100 =
$30.

Hope this helps.
