Give a brief description of how the nitrogen cycle works

1 answer:

4 0

Well, at first, special bacteria convert the nitrogen gas (otherwise known as N2) to ammonia (otherwise known as (NH3) so the plants can use it. Then, Nitrification. Nitrification is the process of converting the ammonia to nitrite ions which the plants can take in as nutrients. Third, after all the living organisms use the nutrients, the decomposer bacteria come and convert the nitrogen rich waste compounds to simpler ones. Fourth, and finally, other bacteria converts the simple nitrogen compounds back to nitrogen gas, (otherwise known as N2), which is then released back into the atmosphere to begin the cycle once more.

Renewable resources can be used without worry about consequences to the environment.

Ugo [173]

The answer is option one "true." Renewable resources are things that can be used repeatedly and can be replaced, which means it doesn't affect the environment. Renewable resources are like: Oxygen, water, wood, and paper all are are renewable sources. Nonrenewable sources are things that cannot be replace naturally which is because the formation of these sources takes millions even billions of years nonrenewable sources include: oil, coal, and some gases.

Hope this helps!

Given the mRNA sequence below, what would tRNA anticodons be in response? A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A

Lesechka [4]

Answer:

U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U

Explanation:

The mRNA (messenger RNA) is produced via the process of TRANSCRIPTION, which is the first stage of gene expression in living cells. The mRNA sequence formed is further read in the ribosomes in a group of three nucleotides called CODONS. This reading is done by another type of RNA called transfer RNA (tRNA).

The tRNA uses a set of three nucleotide bases that are complementary to that of the mRNA codons called ANTICODON. The anticodons are complementary to the mRNA codon i.e. A on the mRNA sequence will be read and recognized by U on the tRNA anticodon.

Hence, given the mRNA sequence: A-U-G-C-C-U-A-C-G-G-G-G-G-C-C-A, the tRNA anticodons that will read this sequence will be: U-A-C-G-G-A-U-G-C--C-C-C-C-G-G-U

1) RNA polymerase finds the promoter sequence on DNA.
2)RNA polymerase reads the DNA and builds complementary sequence.
3) Intron séquences are spliced out and exons are joined together.
4) The ends of the mature transcript are protected before it leaves the nucleus.
5) The mRNA attachés to the ribosome.
6) transfer RNA arrives at the ribosome and the anticodon complements to the mRNA codon.
7)amino acids form peptide bonds as tRNA molecules match the mRNA.
