The Ebola Virus A virus is an ultramicroscopic infectious organism that, having no independent metabolic activity, can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid, either RNA or DNA, surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the genetic code for replication, and the host cell provides the necessary energy and raw materials. There are more than viruses that are know to cause disease in humans.
The problem that effects one out of every ten kids in the United States of America is dyslexia. Although to some people this disorder may be very noticeable, it can really sneak up on you. Most of the time kids with dyslexia aren't recognized until they are about eight or nine.
The most important thing to remember is that is takes time to solve, and sometimes cannot be cured at all. Dyslexia develops during the first six months of gestation. Neurons are churned out in the brain's ventricular zone.
Attached to fibers, the neurons travel to the cerebral cortex, which contains the language centers. Here they hit a barrier, stop and take their place in layers above previously deposited neurons, which is normal.
In the brains of dyslexics, how-ever, there are breaches in the barrier and the neurons enter them, leaving clumps of nerve cells called ectopias, which appear to interface with the brain's ability to receive and transmit certain messages.
They are now finding that dyslexia can run in the family. If you or your other relatives have dyslexia that means that there is a chance that your own child could have it.
Unlike what most people think, dyslexia is not to be blamed on the parent for negligence in teaching reading and writing. Dyslexia is not any ones fault it simply occurs when the barrier in the language center of you brain cracks. In some experiments done by the University of Montreal, they are comparing good adult readers to dyslexic adult readers.
In most cases the adult dyslexics were at about the high school level. When the adult dyslexics were compared to third graders in matching sounds with letters, they scored below the eight and nine year olds that were tested.
It's not just a visual problem, actually they can see the letters fine, it is more of a comparing problem. Dyslexics usually cannot spell simple words by just hearing someone speak them to them.
Some of the most confusing words for them are cat and dog. Although over time the symptoms can be fine-tuned, they never go completely away.
As said before dyslexia is not a disease it cannot be cured with any pill or medicine. The only cure so far is many long and slow classes of multisensory sessions. These sessions go through each letter, sound, syllable, etc.
The fact that you child may have dyslexia doesn't mean that they will be unsuccessful. Some examples of people who have to live d with dyslexia are people like Whoopi Goldberg who is famous for her many roles in the movie industry, another person is Albert Einstein who is famous for the theory of relativity, and Winston Churchill the former Prime Minister of England.
As you can see these people were very successful and influential in their life. In conclusion I have found that children are a real threat to this disorder, especially in the United States of America. We may not have the highest illiteracy rate in the world but the children still need all the language and speech classes that they can fit in their schedule.
Children usually find the ability to read very boring and unimportant.Sylvatic transmission cycles of yellow fever continue to occur in endemic tropical regions.
If the outbreak in Brazil leads to urban spread, U.S. clinicians should adopt a high index of suspicion. Essay The problem that effects one out of every ten kids in the United States of America is dyslexia. Although to some people this disorder may be very noticeable, it can really sneak up on you.
