The radioisotope 16-N will most likely be found in proteins in the ribosome, cell membrane and carbohydrate-metabolism related proteins.
This is because, proteins are synthesized from amino acids which individually require nitrogen for their own synthesis. Also, proteins make up more of the E. coli biomass than do the purine and pyrimidine nucleotides whose synthesis also require nitrogen.
Microorganisms such as the E. coli bacteria, have certain nutritional requirements for growth. These requirements include carbon source, nitrogen source and growth factors.
A nutrient medium provides these nutrients for microbial growth.
Nitrogen is required by microbial cells such as E. coli for use in the synthesis of proteins, amino acids, DNA, and RNA.
A radioisotope 16-N in a nutrient medium for growing E. coli cells will be used in the synthesis of these biomolecules.
However, because proteins are found more abundantly in E. coli cells, the radioisotope 16-N will mostly be found in cellular proteins such as ribosomes, cell membrane and carbohydrate-metabolism related proteins.

Answer:
Primary producers use energy from the sun to produce
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Answer:
Steps to cellular respiration:
1) In the first step of respiration, glycolysis occurs in which glucose molecule is converted into pyruvate molecule.
2) Krebs cycle is also called citric acidity cycle. In this cycle, hydrogen and electron are produced from the oxidation of pyruvate molecule and provides to electron transport chain.
3) Electrons carried by NADH + H and FADH2 are converted into oxygen through a series of electron carriers, and production of ATP occurs.
