Stella wants to test the hypothesis “If carbon dioxide levels increase, the growth rate of sunflowers will increase.” She places five young sunflower plants into similar containers and sets up pumps that release different amounts of carbon dioxide into each container. She plans to measure the daily height of the plants for two weeks and graph the data. Which additional considerations would produce the most reliable experimental results? She should also provide mist to each of the plants to keep the air moist and fertilize the plants. She should record her data in a bar graph for easy analysis.
She should increase her sample size to 50 plants and place them all in the same area. The plants receiving less CO2 should be given a little more water.
She should be sure to give all the flowers the same amount of water. She should make observations twice a day for four weeks for better results.
She should place one flower in a similar container, but not pump carbon dioxide into it. She should also give each plant the same amount of water.

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
