In this assignment, you will prepare a presentation about paralysis and its relation to the central nervous system. Your report will answer questions such as, “What diseases cause paralysis?” “How does the disease damage the central nervous system?” and “What treatments can help reverse paralysis?” The presentation should be seven slides in length. The slides should include the following things:
Title
Introduction – an overview of the presentation
Causes – an overview of one to two causes of paralysis
Causes and the Nervous System – describes how the nervous system is affected, using scientific terms
Treatments – an overview of one to two treatments for paralysis
Effectiveness of treatments – describes how the treatments affect the parts of the nervous system to reverse paralysis
Conclusion
Remember to make a list (bulleted, numbered, etc) on each slide. The slides should feature the highlights of the main idea. The bullet points should be short phrases (at most, one sentence) that highlight some key points.

1. Introduction: Paralysis is when your body looses its ability to move properly. In this presentation I will teach you about paralysis and the properties that make such an interesting disease.

2. What diseases cause paralysis?: Paralysis is usually caused by damage in the nervous system or spinal cord. Another thing that can cause paralysis are stroke, poliomyelitis, cerebral palsy, Parkinson's disease, and many more. These diseases are very harmful to the human body.

3. How does the disease damage the central nervous system?: Paralysis happens when communication between the brain and spinal cord is blocked. Usually by blood clots. When this happens a stroke can occur. But if it damages your spinal cord you could loose all feeling on the lower side of your body.

4. What treatments can help reverse paralysis?: So far there are no treatments that can fully reverse paralysis, but there are rehabilitation treatments. such as Physical therapy and Occupational therapy.

5. What do these treatments do?: Physical Therapy use massages, heat and exercise as a way to stimulate nerves and muscles. Sometimes this can help them get feeling back. Occupational Therapy helps people learn to do every day things again.

6. Conclusion: While I was reading about how paralysis works it occurred to me that so many people suffer not being able to move. I have you have learned a lot from my presentation.

Explanation: hope this helps

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

i think the answer is b.
