I say A not sure tho but I did get a grade 5 in biology
Explanation:

heir function is to base pair with the codon on a strand of mRNA during translation. This action ensures that the correct amino acid will be added to the growing polypeptide chain. A tRNA molecule will enter the ribosome bound to an amino acid.
Answer:
C) an interneuron
Explanation:
A reflex arc is a neural pathway that controls a reflex action. In a simple spinal reflex, the pathway for an impulse is along a sensory neuron directly to a motor neuron through an interneuron because an interneuron enables communications (i.e a pathway for information passage) between a sensory neuron and motor neuron. They play vital roles in reflex actions, neuronal oscillations, neurogenesis in an adult mammalian vertebrate brain.
