Answer:
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.Explanation:
Water is a polar molecule
Brainliest answer please
Answer - The oxygen molecules move, by diffusion, out of the capillaries and into the body cells. While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries. Carbon dioxide is brought, through the blood, back to the heart and then to the lungs.
Explanation:
- Nitrogen molecules is split apart
- Gaseous nitrogen is released
- Nitrogen moves from soil to plant material
- Dead animals decompose
1 through 4 lists the movement of nitrogen from the atmosphere
The process starts with nitrogen being discharged in the atmosphere where its molecules are split apart. Most times electrical discharge from thunder and lightening helps to break and release free nitrogen in the atmosphere. The nitrogen can enter the soil through the activities of some bacteria in leguminous plants. Some enter through rain water that has reacted with free nitrogen in the atmosphere.
Plants use the nitrogen for some of their life functions. When animals eat the plant matter, they later die and decompose and denitrifying bacteria can help return the nitrogen in compounds back to the atmosphere.

The ear cavity (which is affected in infectious otitis) is connected by a duct (the Eustachian tube) to the nasopharynx located behind the nasal fossae.
Otitis is related to a bacterial or viral infection, which most often contaminating the middle ear as a result of rhino-sinusitis or rhino-pharyngitis by borrowing the Eustachian tube or vice versa (otitis media evolving towards a pharyngitis).
