When tRNA matches with the on the mRNA it brings in the corresponding to begin forming the protein.

a) codon b) anticodon

Explanation:

The process of protein formation in a cell is called Translation.

Translation process begin when tRNA enters ribosome. tRNA consist of three nucleotides called anticodon that matches with the codon present in the mRNA. Anticodon in tRNA binds with a specific codon present in mRNA and so results in the addition of amino acids to produce protein chain.

Hence,  tRNA matches with the codon on the mRNA, it brings in the corresponsing anticodon to begin forming the protein.

it should be briana that has it to me

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
