B. marks transformation of ammonium (NH₄ plus) into nitrites (NO₂ minus) by bacteria.
C. marks synthesis of ammonium (NH₄ plus) by decomposers.
D. marks transformation of nitrogen (N₂) from the atmosphere to ammonium (NH₄ plus) by bacteria.
E. marks organisms that take part in transformation of nitrogen from the atmosphere (N₂) into ammonium (NH₄ plus) and are located in the root nodules.
Answer:
D. marks transformation of nitrogen (N₂) from the atmosphere to ammonium (NH₄ plus) by bacteria.
Explanation:
The nitrogen cycle is a biogeochemical cycle which involves transformation of atmoshperic nitrogen into many chemical forms including nitrite (NO2), nitrates (NO3) and ammonium (NH4).
The process of nitrogen cycle starts with the process of nitrogen fixation. In this process several nitrogen fixation bacteria such as cyno bacteria converts the atmospheric nitrogen into ammonium (NH4) in the soil. The resultant ammonium (NH4) can be directly used by plants or transform into nitrites or nitrates through nitrification process.
Hence, the correct option is D.
c. 15%
b. 20%
d. 5%
b. Changing one amino acid in the protein hemoglobin causes sickle-cell anemia.
c. Proteins are sensitive to changes in pH.
d. The shape and chemistry of an enzyme's active site determine its function.
A.) High temperatures cause proteins to denature.
The sequence of amino acids, or the primary structure, in a protein determines its shape and function. Changing one amino acid in hemoglobin results in sickle-cell anemia, showing that small alterations in the primary structure can have significant impacts on protein function.
The primary structure of a protein is important in determining its function. It refers to the sequence of amino acids that make up the protein chain. The option that illustrates this relationship is b. Changing one amino acid in the protein hemoglobin causes sickle-cell anemia.
This statement is valid because the amino acid sequence (primary structure) determines the shape the protein takes. In the case of hemoglobin, a single amino acid substitution causes a significant enough alteration in shape to result in the harmful condition of sickle-cell anemia, thus clearly showing the link between primary structure and protein function.
