Mendel's law of Dominance is demonstrated by these families.
Explanation:
Mendel's Law of Dominance states that the recessive gene will not be expressed in front of Dominant gene. He found that in a heterozygous gene the allele for Dominant trait will mask the trait expressed by recessive trait, also one trait will overshadow the other trait both the traits will not appear in offspring.
Aa X Aa (In first family both parents are heterozygous)
AA X aa ( In second family the father is dominant and mother is recessive and albino, but no child will be albino since all would be heterozygous for the trait.)
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.

The part of the stem that gives rise to this pattern is : B. xylem
xylem is responsible in transporting water and nutrients. It die after a year or so and will leave the concentric pattern as it die
