Generally, hepatitis is not contagious by air. The only way to be infected is to be in contact with the objects that the contagious person used.
Spanish:
Generalmente, la hepatitis no se contagia por vía aérea. La única forma de infectarse es estar en contacto con los objetos que usó la persona contagiosa.
Explanation:
English:
It is known as a fecal-oral way of infection. The hepatitis is spread by blood, sperm, or other liquids from the body of the infected person. The intimate relation without protection is one of the ways.
Also, the drug addicts can be easily infected, if the needle is shared.
Spanish:
Se conoce como una forma de infección fecal-oral. La hepatitis se transmite por sangre, esperma u otros líquidos del cuerpo de la persona infectada. La relación íntima sin protección es una de las formas.
Además, los drogadictos pueden infectarse fácilmente si se comparte la aguja.
What do we know about heredity and sickle cell disease?
Sickle cell disease is the most common inherited blood disorder in the United States. Approximately 100,000 Americans have the disease.
In the United States, sickle cell disease is most prevalent among African Americans. About one in 12 African Americans and about one in 100 Hispanic Americans carry the sickle cell trait, which means they are carriers of the disease.
Sickle cell disease is caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. Hemoglobin transports oxygen from the lungs to other parts of the body. Red blood cells with normal hemoglobin (hemoglobin-A) are smooth and round and glide through blood vessels.
In people with sickle cell disease, abnormal hemoglobin molecules - hemoglobin S - stick to one another and form long, rod-like structures. These structures cause red blood cells to become stiff, assuming a sickle shape. Their shape causes these red blood cells to pile up, causing blockages and damaging vital organs and tissue.
Sickle cells are destroyed rapidly in the bodies of people with the disease, causing anemia. This anemia is what gives the disease its commonly known name - sickle cell anemia.
The sickle cells also block the flow of blood through vessels, resulting in lung tissue damage that causes acute chest syndrome, pain episodes, stroke and priapism (painful, prolonged erection). It also causes damage to the spleen, kidneys and liver. The damage to the spleen makes patients - especially young children - easily overwhelmed by bacterial infections.
A baby born with sickle cell disease inherits a gene for the disorder from both parents. When both parents have the genetic defect, there's a 25 percent chance that each child will be born with sickle cell disease.
If a child inherits only one copy of the defective gene (from either parent), there is a 50 percent chance that the child will carry the sickle cell trait. People who only carry the sickle cell trait typically don't get the disease, but can pass the defective gene on to their children.
Sickle Cell Disease
An inherited disease in which the red blood cells have an abnormal crescent shape, block small blood vessels, and do not last as long as normal red blood cells. Sickle cell anemia is caused by a mutation (change) in a gene.
Answer:
Desert
Explanation:
A biome can be defined as a portion of the biosphere with distinct flora and fauna with respect to abiotic factors such as temperature, rainfall, topography, etc. They play important roles in the sustenance of life on earth.
The major types of biomes that exist in the world include:
- Desert biomes
- Tundra biomes
- Aquatic biomes
- Forest biomes
- Grassland biomes
<em>The </em><em>desert biomes</em><em> are characterized by very little or no rainfalls with high temperature, low atmospheric moisture and low vegetation cover. Because of the high temperature and sun intensity, animals within deserts are mostly active at night in order to prevent desiccation.</em>
<em>Plants within the desert have also adopted some adaptive attributes in order to cope with the harsh conditions. These adaptations include having extensive roots that take in water quickly when available, possession of modified leaves to prevent excessive water loss due to evapotranspiration, etc.</em>
The biome being described in the question is desert.
