I think the correct answer from the choices listed above is option 3. Chemical reactions are important to living organisms because they allow the organism to use matter and energy from the environment for life processes. Hope this answers the question.

Answer: The correct answer for the fill in the blank is 3) They allow the organism to use matter and energy from the environment for life processes.

Chemical reactions form the basis of all life forms on earth. They are involved in all the essential metabolic processes, which are important for the survival of the living organism.

The chemical reactions use matter and energy from the environment in the form of food, which is then metabolized through a series of chemical reactions. This is essential for the survival of the living organism as it helps in the processes like growth, digestion, and respiration.

Thus, option 3) is the right answer.

Nucleotides are the building blocks of dna and rna. One nucleotide is also used in the high-energy molecule (pictured below) ___

Marysya12 [62]

Answer

Nucleotide that use in the formation of high energy molecule is known as Adenine.

Explanation

A single nucleotide is composed of three components, these are:

1. Pentose sugar

2. Phosphate group (phosphoric acid, and

3. Nitrogenous base.

Formation of high energy molecule

ATP stands for adenosine triphosphate is a type of mononucleotide. When adenine and nitrogenous base combine they give rise to another molecule known as adenosine.

Adenine + nitrogenous base → Adenosine

However when one phosphate group is attached to it it become adenosine monophosphate.

Adenosine + posphate → Adenosine monophosphate

Similary when another phosphate is attached it become adenosine diphosphate and the addition of third phosphate lead to the formation of adenosine triphosphate.

Conclusion

Thus is is cleared from the above discussion that Adenine is the main component of ATP (Energy rich molecule).

Complete question...

a) the same codons are assigned to the same amino acids in most living things.

b) the same codons are assigned to the same DNA sequences in most living things.

c) None of these are correct.

d) the same amino acids are assigned to the same DNA sequences in most living things.

The genetic code is ubiquitous- it is found everywhere in most living organisms. Thus a) the same codons are assigned to the same amino acids in most living things. 

Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.

Further Explanation:

The nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.

Basic makeup: C, H, O, P... life on Earth is Carbon based nucleotides contain 5-carbon sugars, and nitrogen; the bases may contain single to double bond rings

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Codons are three nucleotide bases, with each codon encoding an amino acid or signalling the beginning or end of protein synthesis.

RNA codons determine certain amino acids so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Cysteine and Uracil) Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.
