why microscopes are useful in the study of cell biology

Microscopes being invented has opened up a whole new dimension in science. By using microscopes scientists were able to discover microorganisms and study the shape cells and see what small part of plants and animals look like. Today microscopes are used as a tool to diagnosis illness in hospitals and clinics all over the world

since their invention, microscopes have been moved beyond the visible light refracting lenses. Electrons, x-rays and infrared rays are used by far more expensive microscopes to detect even the smallest structures. scanning electrons microscopes are able to resolve viruses, which are far smaller then any cell.

 

 

How Lichens can be environmental indicators.

Lichens are great for environmental indicators because they sense air pollution as well as the concentration of sulfur dioxide in the atmosphere. Lichens are plant organisms that can be found in different exposed places such as tree barks and rocks they are also good at absorbing water and nutrients to grow there.

WAYS TO CLEAN THE AIR

1. try to cyclic or walk to nearby places

2.get ride of your car and use public transport .IE. bus, metro

3.start planting trees to help get ride of co2 editions

4.conserve energy

5.electrical generations is a source of air pollution so conserve electricity

6.conservative electricity by turning of lights in used rooms

7.use less energy by using cold water when ever possible

8.use fans instead of air con

9.reduce, reuse, then recycle

10.buy and use recycled products

11.when barbecuing, use an electric or chimney-type charcoal starter instead of lighter fluid.

12.Use a propane grill when barbecuing

13.drive less in big and fuel wasting cars

14.Maintain your car; it’ll last longer

15.Make sure your tires are properly inflated – you can save $130 a year in gasoline costs

16.

  • Trade your car in for a newer model – newer cars are more efficient and pollute less
  • Don’t “top off” your gas tank – by stopping at the click, you will reduce fumes that contribute to ground-level ozone pollution
  • Avoid idling – in general, turning off and starting an engine uses less gasoline than letting it idle for more than 30 seconds
  • Turn the car off while waiting in line at railroad crossings and drive-thru windows
  • Make sure your car’s air conditioner is working properly – leaky air conditioners in cars are the single greatest source of chlorofluorocarbons (CFCs), a greenhouse gas
  • Clean the condenser coils on your refrigerator every few months – you can reduce electricity consumption 6% or more
  • Use your fireplace less
  • Prevent fires
  • Insulate your home to use less energy
  • Use electric or manual lawn and garden equipment instead of gas-powered equipment

THE REEL ESSAY!!!

    In this essay i will discuss how hip hop still has a positive message.Many people think that hip hop is a bad influence to young people this days but they don’t know about emcees who still rap positively. One way hip hop does this is by criticising the REEL. The REEL is a concept made by Mk. acanty to explain why rappers rap hyper-violent hyper-masculine lyrics. To understand this we have to look in to how hip hop started. Hip hop started in New York in the 1970s when the sugar hill gang released the first hip hop song “rappers delight”. At this point hip hop was about police brutality, the government, the media, as well as discrimination against blacks. This started to get more and more popular and started to get catch the eyes of major record companies, who started to buy this small interdependent labels because they thought it was a money making opportunity. To get more buyers the lyrics began to change into hyper-violent hyper-masculine which, many white suburban consumers admit they enjoyed. At this point hip hop became genetic and rappers became afraid to rap about  social issues because record companies wouldn’t give them the deal.The REEL  is this box rappers feel they have to be in in order to be accepted by listeners. stuff like sealing drugs, killing people and having lots of girls. Rappers put into the minds of young listeners that doing all those stuff means your hard or living the good life. This is what the REEL really is.

Mos Def is one of the few emcees we have studied this year. After listening to one  of his songs ‘mathematics’ you can clearly hear that he is a very social conscience rapper. He raps ‘like i got 16 to 32 bars to rock it, but only 15% profit ever see my pockets’. What he means that he raps all of  his bars but record companies take advantage of his talents and only gives him a small portion of what he earns. This shows that record companies are stealing money from the emcees. He also uses words like ‘profits’ and ‘pockets’ emphasising the s sound. Here he uses semblance, which is used to make the s sound stand out. The s sound also sounds like the start to the word ‘snake’. Snakes are sly and so are the record companies by only giving 15% profit. This is a social conscience issue which is completely the opposite to the REEL. Doing this he indirectly criticises the REEL.

Jayson Mick Jenkins (born April 16, 1991), better known as Mick Jenkins, is an American hip hop recording artist signed to Cinematic Music Group. On December  23, 2013 Mick released a new song called Martyrs. After listening to this song the hook really stands out to the rest of his song. The hook is about getting lots of money and having sex with lots of girls. The last few lines of the hook says “I’m just with my n****s just hanging” What Mick Jenkins is trying to say is that all these stereotypes in hip hop influences young black teens that getting girls, killing and getting money makes you  hard or means your living the good life but it will just get you killed. That is what he means by hanging, which could also mean to be lynched (to be hanged from a tree). He portrays this  in the music video when him and his friends are hanging around with a rope around there neck. Here he is saying what he does in the first part of the hook it is as if he is mocking other rappers who saying this things. The irony here is that he criticises rappers for what they rap but then raps about it. By doing this he is mocking the other rappers. But he treys to use satire instead. Satire is when you use irony to make a point about something socially conscience. Being a socially conscience rapper as we know this is the opposite to the REEL which indirectly criticises the REEL.

Another emcee we have studied is Kendrick Lamar. Kendrick is an American rapper from Compton, California. Lamar embarked on his musical career as a teenager under the moniker K-Dot, releasing a mix-tape that garnered local attention and led to his signing with Carson-based indie record label Top Dawg Entertainment. We studied one of his songs called ‘the blacker the berry’. In his song he indirectly criticises the REEL by rapping about social issues rather then killing other black people. He does this by repenting the pre-hook here he says ‘the blacker the berry the sweeter the juicy’. Here he is making black feel better about them self’s. The pre-hook states that the blacker the person the better the person they are. Kendrick Lamar also relist this song at a significant time. He relisted the song after the death of a young black person, who was shoot by a white police officer. This was a time in america were it was dangerous to be black so by repeating that line a couple of times reassures black people to feel good about them self’s. This is why he uses repetition. This shows that Kendrick Lamar is a very social conscience rapper as he raps about police brutality. this is how Kendrick  Lamar indirectly criticises he REEL.

Overall I think that hip hop still has a positive message. All the rappers have one think in conman. They are all  socially conscience rappers that all criticise the REEL. They all have the same thought about something in this case how they feel about the REEL. This shows that they still want hip hop to carry on as it used to were rappers could rap about social issues and still get there deal from the record companies. This is because they are all social conscience rappers.

Is the merchant of venice anti-semitic?

       The merchant of venice is one of shakespeare’s many play’s. But unlike his many other play’s this one is very controversial. Many people would say that it is racist or anti-semeiotic (which is a form of racism against jews). This is because of the way the jews are treated in the play. Many would say that it is a tragic play and not one you should laugh at but shakespeare intended it to be a comedy. In this essay i would go into depth about why the merchant of venice is anti-Semitic.

Shakespeare might seem like a racist against jews especially in one of his power fullest character shylock. Shylock is a jewish money lender who lives in a Jewish ghetto in venice.that already is racist. This is because the christians at the time believed that lending money was a sin.This is also were the stereotype that jews being good with money comes from. Another racist aspect in venice was how the jews were only aloud to live in the the jewish ghetto, discriminating them to the rest of venice, and if they were to exit the ghetto they must were a red hat so others [christians] know that they are jewish. This is a reason why i believe that the merchant of venice is a racist play.

Shylock is one of main characters in the play, but this Jew is unlike the others in the play. Shakespeare portrayed Shylock by making him, blood thirsty for money. This is shown many times in the play, such as shylocks first line which was “Three thousand ducats, well”. This was part of the bond that shylock and Antonio were discuss. It shows that shylock is interested in the money and that he wants the money. The word “well”makes it seem like he real wants the deal and makes him greedy for it. As well as his opening line shylock loses his daughter and his ducats and cries out saying “my daughter! O my ducats! O my daughter! Fled with a christian ! O my christian ducats!” This shows that shylock loves his money more than his own daughter showing greed. By saying “o my christian ducats ” he is saying that not only his daughter is turning christian but his money as well. This shows the stereotype that jews love money.

Shylock being a jew also gets miss treated in the play. This is because jew were not liked in this time. Shylock gets miss treated many times in the play,for example”fair,sir you spat on me we Wednesday last,you spurned me such a day, another time you called me dog. And for these courtesies i’ll lend you thus much monies”.these are some of the many times shylock is miss treated in the play. He is refereeing  to all the times Antonio has disrespected him and on that if he should give him the money or not. Shylock says that he spat on him which is very disrespectful as well as calling him a dog just because he is jewish. The “hath not a jew eye” speech also shows that Antonio has laughed at his losses and mocked his gains as well as showing how equal both jews and christians. This shows the discrimination agents jews in the merchant of venice.

Shylock getting all this disrespect from Antonio and his friends builds anger for shylock and makes him what to kill Antonio. Shylock got his chance when Antonio came looking for him and asking him for money. This is when shylock and Antonio disgusted a bond or a contract. Shylock then said that if Antonio does not pay back him in time then he will take a pound of Antonio’s flesh. This shows the anger and rage of shylock and how badly he wants to kill him. This also links in with a stereotype that jews use christian flesh in worship or religious upbringing. that made many characters in the play angry and made shylock look like a beast. Shakespeare must of intended that to happen because of all the other stereotypes in the play.

Shakespeare shows victory in christians and not jews and also shows that  jews are worth less. He makes all the judges in the court christians because he does not what shylock to win and wants to make it un fare for him as much as posable. He also wants people to laugh at shylock making him look like a fool and not liked in many ways in  many ways. This is because shakespeare intended his play to be a comedy not a tragedy. This means that shylock is ment to be laughed at as if he was the fool or the clown of the play. I know this because at the time jews were hated by most of the christians in the time the play was wrote. It shows that Shakespeare does not like jews since he made a play discriminating jews.

But its not only the people of venice that don’t like jews it is all so the court and the law in venice. when Antonio was put in court by shylock the duke was alone with antonio before the trail started. The image we get is that the judge or duke is not impartial because he supports Antonio by saying he feels ‘sorry’ for him because he is being trailed by a ‘stony adversary’ (which means shylock is a villain or an enemy) who is ‘incapable of pity’. The first insult means that he can no give pity as if he was an animal. he also states that shylock is an ‘inhuman wretch’. This shows that the duke feels that shylock is not like a human but an animal, and is two-faced. The insults and help all implies that the duke is o Antonio’s side.

To conclude in believe that all though jews like shylock were hated and disrespected that Shakespeare him self might not be a racist him self. This is because even though he made shylock the victim he might have not felt the same way. I believe this because as a play writer he would want to make a play popular and liked by the people in his time and because many people hated jews at the time he might of thought that he will make a comedy discriminating jews so that the people like the play even though he might not feel the same way about jews. But i do think the play its self is racist because of all the factors against jews in the play. All the points just goes to show how much jews were unliked in venice.

                              THE END.

Paragraph three draft for the merchant of Venice essay!!!
