Answer:
Methemoglobinemia
Explanation:
Methemoglobinemia (also known as the blue baby syndrome), is a condition with multiple etiologies which is associated with the lack of oxygen in the blood. This syndrome affects the function of red blood cells by altering the amount of hemoglobin protein, which carries and distributes oxygen to the body. Methemoglobinemia may be acquired by exposure to drugs and/or toxins. In this regard, it has been shown that high levels of nitrates in the water may induce this syndrome in infants.
The correct answer is - phototrophs.
Some of the autotrophs are able to convert the electromagnetic energy from the sunlight into chemical energy in the form of reduced carbon (C). The autotrophs that are able to perform this are called phototrophs. The green plants and the algae are the most prominent members of the phototroph autotrophs.
In essence, the autotrophs are producers, meaning that they are able to produce their own food. The phototrophs are the part of the autotrophs that are able to use the sunlight to produce small amounts of ATP as well as the energy carrier NADHP. By producing the ATP and the NADHP the phototrophs manage to produce glucose, or rather sugars, which are actually their food.

<span>Cells control cell division in order to maintain normal cell function. If something happens to the control of the cell division, the healthy cells will divide uncontrollably. These new cells are cancer cells. </span>
The mutations in three genes are responsible for development of cancers:
1. Mutation in proto-oncogenes. Proto-oncogenes normally signal cells to grow and differentiate. Proto-oncogenes can become oncogenes due to mutations which result in the uncontrollable division of the cells.
2. Mutation in tumor suppressor genes. In normal cells, tumor suppressor genes suppress genes essential for cell cycle and that way they prevent uncontrollable cell division. However, after a mutation in these genes, suppression is lost and the cell may progress to cancer.
3. Mutation in stability genes. In normal cells, they have no role either in cell death or growth, but they control mutation rate. Mutation in stability genes results in situation where all genes, including proto-oncogenes and tumor suppression genes, are more frequently mutated.
