__Invertebrated - Assignment__ Invertebrates can be very useful in our lifes, and also can be bad for our lifes. We are mainly talking about insects or Arthropods. To see the good and bad part of invertebrates in our life we have to see it from the human point. Invertebrates are good for nature and for us as well sometimes.


 * The bee** is an invertebrate that gives us its natural products such as honey, real honey, jelly, etc. that is rich in proteins.
 * The Bogavante** is good gor the human's body.
 * The crisopa** is the predator of a animal called "Pulgon" wich is full of bacterias. Talking about society for the agriculture, because with bad crops, humans are unhealthy.
 * The Spider** is the predator of the fly, grasshopper, etc wich are bad for our health oftenly.
 * The fruit fly** is an invertebrate that helps a lot in science.

Talking about some bad invertebrates for us and for society...


 * The butterfly of the "Col"** is bad because it can cause several infections to the human body by the "Colifor" and/or "col"
 * The domestic fly** is a conductor of different germs.
 * The "Pulgon**" can transmit different deseases or infections.
 * The "Tabano"** causes hurt in our pets' skin

In our house, part of society...


 * The clothe fly** causes damage to our clothes, book or other thigs that are in our closet.
 * The silver fish** causes damage to book and other house material.

__Global Warming__

Global Warming is the increase of the average temperature over the year. We usually take a reference of this by green gouse effect, but Global Warming is a Green house effect in excess, the ultra-violet rays of the sun are going into the Earth in a proportion that is causing damage to the Earth. But how can the ultra-violet rays can enter into the Earth if we have the Ozone layer? Here is the answer the Ozone layer is been destroying by us and the actual hole it has is of 27 million of kilometers and it will last 50 years to "close" again. The main cause of global warming is Contamination. We contaminate the environment and now by Industry we are trying to fix it by doing products to contaminate less. But the real issue is that we, Society are contaminating and this contamination breaks a balance in the atmosphere, this makes a big hole in the ozone layer that allow the ultra-violet rays to come in. We are killing our protection layer! Now we know that all cause has an effect, and this is going to be the consequence, forest because of deforetation will be deserts we will have problems with respiration because of the less oxygen is going to be. Water will be very difficult to find and maybe we will have Cancer. So let's propouse some solutions. 1- Try to use less paper. 2- Recycle. 3- Use biodegradable products. 4- Let's make think our parents about global warming. 5- Educate an adult abpur Global Warming. 6- IF WE DON'T HAVE SOLUTIONS ENOUGH FOR GLOBAL WARMING SO JUST LET'S STOP CONTAMINATING!!

Find functional and technical diferences between SEM and TEM. Use images to support it.
 * __Biology__ **

What is SEM? SEM or the __Scanning__ Electron Microscope is a Microscope taht uses electrons to form an image while you are observing a sample. SEM uses electrons instead of light. The SEM allows you to have images of high resolution, that means that either if you have less amount of the sample you always are going to have good images to observe. SEM today is one of the most used microscopes in the world. How does SEM works? In light microscopes we have lens to boserve better the things, we use lens made of glass because the glass makes light bend and focus on a specific part. But this light microscopes are not so eficient to see tiny things as atoms, for this type of things we use electron microscopes. But we don't use lkight for elctron microscope we use magnets. Magnets will make the force of the elctrons bend, this magnets let us magnify the images and bring them into focus.



What is TEM?

The TEM or __Transmission__ Electron Microscope is the microscope that works with electrons instead of light. The TEM is microscope that works with a beam of elctrons that are transmitted to a a ultra fine sample, this electrons interact with the specimen or sample and when are passing throught the image forms in a high resolution. So we can say that this micrscope works with the interaction between electrons and the sample.

What are the functional and technical differences between SEM nad TEM?

In functional we can say that they are practically the same, because both of them work with electrons and their objective is to do the images of the tiniest objects in high resolution, but in technical we have differences. SEM works with elctrons and Magnets to do the image in high resolution, while TEM works with the transmission and interaction of electrons with the sample. In SEM the magnets act as glass in light microscopes in TEM is an quickly interaction.
