People who have Alzheimer's disease experience an increasing loss of brain function and cognition over time. Alzheimer's is characterized by a buildup of abnormal protein fragments that damage brain cells.

Which statement explains how BACE2 most likely works? BACE2 speeds up the reaction that breaks down the abnormal protein fragments.

Which excerpt from the awakening best highlights the elation edna feels when she thinks of robert? the morning was full of sunlight and hope. edna could see before her no denial—only the promise of excessive joy. she lay in bed awake, with bright eyes full of speculation. “he loves you, poor fool.” he would come to her in the afternoon or evening, sit and roll his cigarette, talk a little, and go away as he had done the night before. but how delicious it would be to have him there with her! robert did not come that day. she was keenly disappointed. he did not come the following day, nor the next. each morning she awoke with hope, and each night she was a prey to despondency. his horses were full of mettle, and even a little unmanageable. she liked the rapid gait at which they spun along, and the quick, sharp sound of the horses' hoofs on the hard road.
