Question 1 of 5 Joaquin is doing an experiment with a ramp and a ball. He
wants to know how the slope of a ramp will affect the
speed of the ball when it reaches the end of the ramp.
Which step allows Joaquin to use his imagination in this experiment?
A. Identify the variables in the experiment.
B. Accurately record the results in a data table.
C. Decide which type of ball to use.
O D. Measure the angle between the ramp and the floor.

Very hard to understand

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
