Selective Breeding

22 BILLION

The grow rates of chicken through selective breeding more than doubled in the past years because of how many chickens the people in the world eat every year.

Every year there are 22 billion chicken eaten by the people in the world, that is why every compony and every farmer started selective breeding, breeding for particular genetic traits. And genetic modified breeding (GM) where the human directly manipulates the genetic of an animal or plant.
The selective breeding is good in a way, because the human is not taking away or putting DNA from or to an animal to get just on solution, but is slowly aiming and pushing in the direction they want to go, like not haveng fedders or growing faster. And in this way the DNA from a animal doesn't change so fast and you don't get something completly new and unknown but something known with a new special trait.}

All this, selective breeding and GM just happened because of the econmy. Everybody wants to grow more chicken, faster and better. But because that is not in the chickens nature the human had to help it through this selective breeding or GM. Especially the big componies do that, but they are not doing it in a fair way. The chicken are with way too many on a way to small space and grow too fast for their normal conditions just becuase the human wants them to and wants to make more money of the chicken and that only works if the chicken grow faster and are heavier by the time they are slaughtered. So this became a competion and race between the big componies and the little farmers to make more money.
But since the big componies have more space and more money to produce those kind of chicken the little farmers can't go with this speed anymore and don't make any money of their business.

I think the only way to stop this, manipulating the chickens DNA and nature is to stop the fast and amazing high consume of them. But since everybody likes to eat chicken and likes to have it cheep, this is hard to make it happen. An other way to stop this fast growing and welfare of the chicken is to not allow the componies to grow that many chickens on such a small space. But the same here, everybody likes it cheep and good so they contribute to the econmy through their high consume of this product.
If we would stop this massgrowing of chicken we would also help the little farmers who can't keep up with the speed of the big componies right now.

I think Mendel wouldn't like what the humans did with his discoveries from the 1800 because we are overusing it and pushing it too hard and even harder just to make more money and get everything for a lower price.

A world without mosquitos

1. Yellow Fever, Dengue Fever and Japanese enecephalitis

2. There are 3,500 named species of mosquito

3. They have been on earth for more than 100 million years.

4. If the caribous wouln't be there, the mosquitoes couln'd drink any blood, and the caribous wouldn't eat the grass, transport nutrien or feed the wolves the whole ecosystem would be out of order and there wouldn't be ant ecosystem in this area.

Definition of Biology

Bilogy is the science of the life and it's basics. It includes many specialies.

Personla Touch



Life History: Males may live up to 20 years and females to 30 years. Males reach sexual maturity at 3-7 years but do not hold territories on breeding rookeries until 9-13 years. Females start breeding at 3-7 years and spend the next two decades either pregnant or lactating. Females are bred in June, but the fertilized egg does not implant until October. Single pups are born the following June, with birthdates at southern rookeries earlier than births at northern rookeries. Twins are rare. Pups suckle from 1 to 3 years, with most apparently weaning after their first winter

Purpose of my Biology Blog

I have a Biology Blog, to upload assignments we had to to at school or at home. With this Blog I can publish my work, so everybody can see it, also I can create my own Blog however I want to.



Project Reflection

1. We were talking about the body in general in class, and that lead to this project. We started to focus on our inner body and its single systems it has in it. 
     
2. The purpose of this project was, that the class splits up in several groups and each group works together to get a final product, our website, and get experts in our topic.
   
3. To decide who is doing what, for the final product, was decided before the actual project started, we were handed out a piece of paper where we could read on what each topic or each member has to do if he chose that topic. So we chose what we wanted to do and then we were put together in groups of about 4-5 with all different persons who were focusing on his own role to bring together the website with his teammades.
   
4. My role was Creative Media 1. I was responsible for the research about how our system, nervous system, works, and after I did this, I had to produce a mini-project to represent what our system is doing.
5. I'm proud of my mini-project, because this shows everything I have learned during this project. I would like to refine my project describtion more, bring more detailed information into it. I will ry in the next project to give the audience a more detailed view into the project, so they understand it the same way like I did without reading all the information I had to read to get the final product. I think it is relevant because this shows me what is going on inside of my body, and what is making me move and feel. I will take away a lot of things, I learned a lot about disection this year and also about our body, and what is inside of us, our blood and about deseases.

TED Talks: Viral Pandemics Nathan Wolfe

Nathan Wolfe is a doctor and is talking about when HIV was covered and about the bad things about HIV in his speech.
He starts wit, h the very begining of HIV virus which was incovert in 1929 in Africa in the blood of monkeys.
The HIV virus was tranfared from the monkeys to human bush hunters who cut these monkey up and came in contact with the monkeys blood.
He also talks about other virusus which soread from animals to humans like yellow fever, ebola and some other.
He thinks that some reasons why we should be conceren about bushmeat ( monkeys) are that there is a high chance that humans become viruses from animal blood and that when the bush hunters dont sop hunting these animals they will die out.
Also he talked about monotoring what means tracking viruses.
The main objective of Nathan Wolfe's speech is provention. We need to see, catch and track the viruses that are dangerous for humans before it goes global.

Tests on pics

http://www.focus.de/panorama/welt/tierversuch-das-ist-barbarei_aid_470827.html

In Austria professors made experiments with pic. They wanted to know how long pics can survive under the snow.
They made some of the pics made pass out, conected them to machines and took informations from these to see how long these pics would suvive without oxigen until they die.
Other pics where sticked into the snow with their head above the snow and the people waited until they died because they freezed.

All these expierminets were made to take away some new causes of diing under the snow for humans and to invent new things that could help the human to survive when hes caught under the snow.

After 2 and a half days the pfoffesors had to stop their expirmients becuase they couldnt work anymore under these conditions. When they can keep going on with their projects is unknown yet.

eva vertes ted talk

Eva Vertes is a young girl who loves medical books and she wants to be a active part of the medical world.
With 14 years she started working in a lap at a university and started reading about alzheimer.
After that she heard about cancer stamcells and she wasnt able to put these to things together at first. Her opinion is that cancer is one of the most fear disease of our time and she is fascinated by cancer tumors who actually starts at a stamcell. The more she read about cancer the more she got a different look at cancer. She says that cancer is a direct result of injury. Like when you smoke, lounge cancer is caused or when you break your arm, bone cancer is caused. So she thinks that cancer is a repair response of our body that our body can not really contole yet. But something else she is thinking of, she thinks if we eliminate cancer we come back to the point where a part of our body was demaged, that the body was trying to fix. So shouldn't we rather try to manupulate the cancer than eliminate it?!
She is wondering why she has never heard about heart or any muscle cancer. So there must be anything that is in our muscles that protects them. They are recisted to cancer or any other form of diseases. So if there is anything in our muscles that protects them maybe we could use this as a solution to "fight" against or even with cancer in the future.

So the aim is, to use cancer as a theraphie against the other diseases.

Letter, Liver Disease

Dear policy-maker

I'm John Smith, 83 years old and I have a liver disease and need a liver transplant.
I know I'm not the only person who needs a liver transplant but let me tell you why I diserve this transplant.
First of all there is a very high chance that my transplant is successful because I am becides my liver disease in good health and I want to live for many more years.
I hace six children and 16 grandkids with who i want to spend a long time with.
When I was younger I was a nurse in WW2 and helped our soldiers, maybe relatives of you. I think one important reason why I have a liver disease is my hepatitis C which I got from our soldiers.
I hope I convinced you that I'm the right person for this liver transplant.

Thank you.
