Sickle cell anemia is an inherited form of anemia, a disease that is characterized by inadequate healthy red blood cells to transport an adequate level of oxygen throughout the body.

Normally, red blood cells are flexible and round, and move easily through the blood vessels. In sickle cell anemia, red blood cells become stiff and sticky, and they are sickle-shaped or crescent-shaped. These irregularly shaped cells can get stuck in small blood vessels, which can slow or block the flow of blood and oxygen to different parts of the body.

This disease occurs due to mutations in the HBB gene, located on the short arm of chromosome 11, which encodes the beta-globin protein. This beta-globin is a subunit of hemoglobin which is found in blood erythrocytes.

Hemoglobin allows red blood cells to carry oxygen from the lungs to the entire body. In sickle cell anemia, abnormal hemoglobin causes red blood cells to become stiff, stocky and deformed.

Xylem cells for instance are complex cells located within the vascular tissues of plants and help transport water and minerals to the rest of the plant from the roots. Xylem cells look long and tracheal which is to enable them carry out the aforementioned roles.

What is the purpose of the carbon cycle?
Leno4ka [110]

Answer:

The purpose of the carbon cycle is to utilize the carbon by the organisms such as plant which uses carbon in the form of carbondioxide for making food. This carbon is stored in the form of glucose. When this food is eaten by the animals, it is broken down into simpler substances and carbondioxode is released in the atmosphere again.

Some carbon is present in soil which is used by microorganisms such as bacteria. So carbon cycle is very important for the survival of life on earth.
