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.
Answer:
Transformation
Explanation:
The experiment of Griffith on S. pneumoniae leads to the conclusion that the bacteria can take the DNA from the surrounding environment by the process of "Transformation".
He selected the two strains of bacteria, the smooth pathogenic strains (S strains) and the rough non-pathogenic strain (R strains). When he injected the dead S bacteria and live R bacteria, he obtained the live S bacteria from the mice.
He was amazed at how the dead S strain bacteria became alive and concluded that the dead S strain bacteria were transformed into the live S strain bacteria and named the process transformation.
The transformation process refers to the uptake of the DNA material from the surrounding environment.
Thus, transformation is the correct answer.
