With respect to the cases of early-onset Alzheimer’s disease are inherited, a type known as familiar Alzheimer’s disease (FAD), the statement is best supported by this information is that FAD is the result of a genetic change in one or more chromosomes.

Explanation:

Options for this question:

FAD is the result of a genetic change in one or more chromosomes.Natural selection will continue to reduce the incidence of FAD.FAD affects only the genes of middle-aged people.Deletion of one amino acid causes FAD.

Alzhaimer's disease is a type of dementia that is characterized by neuronal degeneration, causing disorientation, memory and manual skills loss , among others. The familiar variety (FAD) is hereditary and is associated as a cause of disease and early Alzhaimer, before 60-65 years.

So far, three types of mutated genes related to FAD have been established:

PSEN₁ or presenilin-1 gene , more frecuent.APP or amyloid precursor protein gene. PSEN₂ or gene for presenilin-2, very rare or uncommon.

In some cases, people affected by FAD have alteration in more than one gene at the same time.

For this reason, it can be stated that FAD is the result of a genetic change in one or more genes or chromosomes.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
