Which of the following statements about Alzheimer's disease is TRUE? Alzheimer's disease is not associated with the progressive neurodegenerative disorder, dementia Alzheimer's patients produce small amounts of a variant of the amyloid B-protein Tau proteins make up the amyloid plaques that form in the spaces between nerve cells Neurofibrillary tangles are formed from a collection of misfolded tau in the neurons of Alzheimer's patients

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 cause 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. The solutions in the arms of the 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. a. Initially, side A is (hypertonic / hypotonic / isotonic) to side B. Please circle or indicate your answer choice. b. After 2 days, side A will have (higher / lower / unchanged) volume compared to side B. Please circle or indicate your answer choice.

Amyloid plaques observed in Alzheimer's disease are located and contain in the extracellular space ; tau in the intracellular space ; microtubule associated protein in the extracellular space ; beta-amyloid in the intracellular space ; beta-amyloid
The cytoskeleton of a neuron is very important for neuron function. Alzheimer's disease is an example of a central nervous system disease related to cytoskeleton dysfunction. How are the proteins "tau" and "amyloid" related to Alzheimer's disease (AD)? Please elaborate on this question as much as possible.
