All controlled experiments would have only one variable. If there were more than one variable the outcome of your experiment could be for multiple reasons and thus you would not be able to test whether your specific hypothesis was valid.

Control group doesn't change any way.
Answer:
A). True
Explanation:
tRNA, which means transfer RNA is one of the three types of RNA known in nature. The tRNA is found in the ribosome, where it plays a pivotal role in protein synthesis (translation). Transfer RNA is the RNA responsible for reading the nucleotides in the mRNA codon and carrying the amino acid that corresponds those codons to the ribosome.
The tRNA has a 3-dimensional structure that allows it to carry anticodon that reads codon and also carry amino acids on opposite ends. Hence, according to this question, tRNA is a type of RNA that delivers amino acids to the ribosome during protein synthesis.
Answer:
b. Red cars are more difficult to view in the evening and are therefore more prone to accidents in medium-light conditions
