Amutation results in an organism that lacks the ability to make one amino acid .what is true of this organism ?
a. the organism's ability to rna has been changed
b. a gene has undergone a change in the organisms dna
c. ribosomes in the organism do not function properly
d. all the above

The correct answer is-

b. a gene has undergone a change in the organisms DNA.

DNA ( deoxyribonucleic acid) contains instructions for protein synthesis in the form of codons ( a sequence of three nucleotides), which code for particular amino acid. DNA is converted to mRNA ( through transcription), which is then converted to proteins ( through translation).

As per the question, a mutation in an organism has lacked the ability to make ( incorporate) one amino acid.

This means that there is a change in the codon ( that is change in the gene) in a manner such that now the mutated codon will not code for any amino acid.

Thus, option b) is the right answer.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.

explanation:

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes
