Which is a pathophysiologic change that is consistent with Alzheimer disease?

The correct answer is - occurrence of  amyloid plaques and neurofibrillary.

Explanation:

Neural thread protein known as tau protein responsible for the stabilization microtubules, in patient of Alzheimer these proteins are chemically modified and tangles or twists into paired helical filaments called neurofibrilary tangles.

In specific region of of brain have strokes which is focal cerebral infarct, Abnormal cholinergic system is associated with this seizure disorder. Amyloid plaques are misfolded proteins aggregates that are present in the space between nerve spaces associated with Alzheimer disease.

Thus, the correct answer is :  occurrence of  amyloid plaques and neurofibrillary

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
