Indicate whether each of the following statements is likely to be true or false. Integrins are transmembrane components of “adhesion belts”.   Tight junctions seal the plasma membrane of adjacent epithelial cells together. This makes it possible for directional membrane transport across the epithelial sheet to occur. Gap junctions are important structures for coupling the electrical and metabolic activities of adjacent cells. Gap junctions are always open. Extracellular matrix plays an important role in tissue formation and regeneration.

A patient receiving  haloperidol as begun to show signs of tardive dyskinesia. What signs alerts the nurse to this condition?

A variable force F is applied to a block, and the relationship between the force and the block’s displacement is shown in the figure. x1 = m, x2 = m, x3= 30 m, F1= N, F2= 30 N, and F3= N. The positive directions of the force and displacement are the same (toward right). Calculate the work done by the force as the block moves from displacement x1 to x2. Express your answer in joules (J).
