Answer:

A DNA mutation causes sickle-cell anemia.

Explanation:

Sickle cell anemia is caused by a single code letter change in the DNA. This in turn alters one of the amino acids in the hemoglobin protein. Valine sits in the position where glutamic acid should be. The valine makes the hemoglobin molecules stick together, forming long fibers that distort the shape of the red blood cells, and this brings on an attack.

Triss [41]

The significant abiotic by-product of photosynthesis is oxygen. The main product of the process is glucose, which the plant uses as food. The general equation for photosynthesis is:

6CO2 (carbon dioxide) + 6H2O (water) = C6H12O6 (glucose) + 6O2 (oxygen)

It can be seen that plants are important to sustain life because they reduce the earth's carbon dioxide, and replace it with oxygen.
