Trace the flow of blood as it leaves the Left Atrium to exit the left side of the heart and enters the systemic circuit. From the systemic circuit, this radioactive drop of blood returns back into the right side of the heart. From the right side of the heart, the radioactive drop of blood continues to leave the right side of the heart to enter the pulmonary circuit before returning back into the Left Atrium. Follow the flow of blood as it leaves the Left Atrium and the Left heart and returns back into the Left Atrium, after going through the arterial system and venous system of the cardiovascular system:

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.

Ihave made a synthetic cell by placing a solution that is 10% sodium chloride inside a semipermeable membrane through which water can pass but not sodium chloride. if i place this cell into a solution that is 20% sodium chloride what will happen to the size of the cell? will it increase, decrease, or stay the same in size?
