1 answer:

4 0

Acorns of bur, pin and red oaks can be planted in fall or stratified seed can be sown in spring. When planting acorns, place the seeds one-half to one inch deep. Choose a planting site where the oak seedlings can receive good care for one to two years before they are transplanted to their permanent locations.

What is one of the biological uses of Nitrogen? PLZ HELP

Lisa [10]

Nitrogen is a fundamental element required during the growth and development of any organism.

Nitrogen is a fundamental chemical element required to synthesize different biomolecules such as nucleic acids (either DNA or RNA) and proteins.

Amino acids are the bounding blocks of proteins, whereas nucleotides are the building blocks of nucleic acids, and both contain nitrogen.

All organisms in their growth phase requires nitrogen in order to synthesize these biomolecules (i.e., nucleic acids and proteins).

In conclusion, Nitrogen is a fundamental element required during the growth and development of any organism.

OlgaM077 [116]

Answer:

With respect to the differences in the DNA sequence of six species, including the human one, it is true that the DNA sequences may vary but the aminoacid sequences are identical.

Explanation:

Options for this question:

<em>The DNA sequences may vary but the amino acid sequences are identical. </em>
The nitrogen bases in the nucleotides must also be different in each.
The process in producing additional DNA, replication, is identical in all six.
The process of producing DNA, or replication, varies due to the differences in the DNA codes.

The different species that exist have specific genomes for each of them, this is the <u>genetic information contained in the DNA varies from one species to another</u>, as can be seen in the scheme (see image). However, the genetic code is universal, and does not vary from one species to another.

The genetic code is found in the RNA molecule and is a sequence of nucleotides that, organized in triplets (codons), are responsible for the synthesis of specific amino acids. An RNA molecule contains the information necessary for protein synthesis.

The scheme shows the differences of five species with respect to the human, based on the respective DNA sequences. But what it does not show is a universally accepted truth, that the nucleotide sequence encoding an amino acid is the same for each of these species.
