Question

2. Alzheimer's Disease is a neurodegenerative disease that affects the brain and results in severe memory loss. The brains of patients with Alzheimer's Disease show abnormal accumulation of damaging proteins called amyloid plaques and tau tangles that impair normal brain function. The plaques and tangles lead to severe cell death and causes a decrease in brain function and brain size. Alzheimer's patients also have an increase in impaired lysosomes. What do you think is the potential link between impaired lysosomes and the progression of Alzheimer's disease? Please limit your answer to 2-4 sentences. (1 pts.) 3. The solutions in the arms of a U-tube are separated at the bottom of the tube by a selectively permeable membrane. The membrane is permeable to sodium chloride but not to glucose. Side A is filled with a solution of 0.4 M glucose and 0.5 M sodium chloride (NaCl), and side B is filled with a solution containing 0.8 M glucose and 0.4 M sodium chloride. Initially, the volume in both arms is the same. Side Side A Initial setup B U 0.4M glucose 0.5M NaCl Membrane 0.8 M glucose 0.4M NaCl a. Initially, side A is (hypertonic / hypotonic / isotonic) to side B. Please circle or indicate your answer choice (0.5 pts.) b. After 2 days, side A will have (higher / lower / unchanged) volume compared to side B. Please circle or indicate your answer choice. (1 pt.)
