b) Plaques
c) Amyloid beta
d) Memory loss

Answer 1

Alzheimer's disease is characterized by neurofibrillary tangles formed by fragments of tau protein inside the neuron.

Step-by-step explanation:

Alzheimer's disease is characterized by neurofibrillary tangles. These tangles are formed by fragments of tau protein inside the neuron. The tau protein normally provides structure and support to the neuron, but in Alzheimer's disease, it becomes abnormal and forms twisted tangles. These tangles interfere with the normal functioning of the neuron and contribute to the progression of the disease.
