Answer:
Sickle cell anemia is an inherited condition in which there aren't enough healthy red blood cells to carry oxygen through an individual's body. The red blood cells of a healthy individual are flexible and round, and they move through blood vessels with no problem, transporting oxygen successfully. However, a person with sickle cell anemia has rigid, sticky red blood shaped like sickles or crescent moons. These cells often get stuck in small blood vessels, which can slow or block blood flow and oxygen delivery to different parts of the body.
The sickle cell anemia trait is found on a recessive allele of the hemoglobin gene, while the regular red blood cell trait is found on the dominant allele. This means that a person must have two copies of the recessive allele (one from their mother and the other from their father) to be born with this condition. People who have one dominant and one recessive allele or both dominant alleles will have healthy red blood cells.
Answer:
Atmosphere, plant, animals, fossil fuels.
Explanation:
Carbon Is the essential elements needed for life.
Carbon cycle is the movement of carbon from the atmosphere to the Earth.
Carbon move in the carbon cycle and start from the atmosphere.
In the atmosphere, carbon react with oxygen and it is inform of carbon dioxide. Plants use the carbondioxide along with water,and uses light energy from the sun to produce carbohydrates through a process of photosynthesis.
Animals get carbon from plants after consuming plants.
During respiration, carbon atoms are released to the atmosphere.
Some human activities like burning of fossil fuels releases carbon to the atmosphere.
It adds more carbon into the atmosphere
It’s an infectious agent that causes disease
