Answer:
A
Explanation:
monosaccharide is derived from mono, meaning "one", and saccharide, meaning "sugar". The common monosaccharides are glucose, fructose, and galactose. Each simple sugar has a cyclic structure and is composed of carbon, hydrogen and oxygen in ratios of 1:2:1 respectively. Although each sugar mainly exists as a cyclic compound, it is important to note that they are all in equilibrium to a small extent with their linear forms.
While galactose and glucose are composed of six-membered rings, fructose has only five carbon atoms bonded to each other in ring form.
We quantified the number of neurons, senile plaques, and neurofibrillary tangles in a high-order association cortex to evaluate the link between dementia, neuronal loss, and neuropathological findings in Alzheimer's disease (AD). Using statistically unbiased, stereological counting techniques, we examined the superior temporal sulcus in 34 AD patients and 17 non-demented control volunteers. In non-demented control patients, the quantity of superior temporal sulcus neurons remained constant from the sixth to the ninth decade. More than half of the neurons in AD were gone. Both neuronal loss and neurofibrillary tangles grew in tandem with the length and severity of the illness, although neuronal loss outweighed neurofibrillary tangle accumulation by a factor of many.
<h3>What is Neurofibrillary ?</h3>
Inside the brain's cells are twisted fibers that are intractable, called neurofibrillary tangles. Most of the tau protein, which is a component of the microtubule structure, makes up these tangles. From one area of the nerve cell to another, the microtubule facilitates the movement of nutrients and other vital molecules.
These tangles interfere with the transport mechanism of the cell, impairing synaptic transmission between neurons. New research reveals that aberrant tau and beta-amyloid proteins, along with a number of other factors, may play a complex role in the development of the brain abnormalities associated with Alzheimer's disease.
A decrease in concentration and function of acetylcholine (ACh), a neurotransmitter crucial for processing memory and learning, is observed in Alzheimer's disease patients.

*A slab push is a term given to tectonic plates that cause pressure from a down-dip motion. An example of this type of plate structure is where the Nazca plate and the South American plate meet near Peru
Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.
