Salt is better correct answer
Enzymes are catalysts that can be used more than once. If a substance needs to get broken down then it can use the corresponding enzyme to attach itself and break it down into simpler substances. After this is gone, the next substance might come up and attach itself to the enzyme like a lock-and-key model.
Therefore the answer is A) Enzymes accelerate chemical reactions without getting used up in the process.
Answer:
Nucleus: an organelle that is in most eukaryotic cells that contains genetic material for the organism
Ribosome: particles consisting of RNA and proteins that perform protein synthesis
Endoplasmic Reticulum: a network of membranous tubules within the cytoplasm that has ribosomes connected to them, involved in protein and lipid synthesis
Golgi Apparatus: a complex of vesicles and folded membranes within the cytoplasm, involved in secretion and intracellular transport

Answer:
In the genetic code, a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation into protein
Explanation:
Proteins are based on polypeptides, which are unique sequences of amino acids. Most codons in messenger RNA (from DNA) correspond to the addition of an amino acid to a growing polypeptide chain, which may ultimately become a protein. Stop codons signal the termination of this process by binding release factors, which cause the ribosomal subunits to disassociate, releasing the amino acid chain. While start codons need nearby sequences or initiation factors to start translation, a stop codon alone is sufficient to initiate termination.
Answer:
A sharp, ringing sound made by the collision of sonorous (especially metallic) bodies.
