What is Alzheimer’s Disease and how is it caused from the chromosomes?​

Answers

Hey There!_____________________________________Answer:_____________________________________[tex]\Huge\textbf{Alzheimer's Disease}[/tex]

Alzheimer's disease is irreversible progressive degeneration of neurons of the brain (especially Cerebral cortex and hippocampus). It is a brain disorder which starts with loss of memory and conditions worsen upto where a person is not able to perform simple tasks. The disease progresses in three broad stages, and the symptoms are visible in mid 60's.

At first, the patient notices forget fullness. Symptoms of dimentia are evident.In the second phase, there is a severe loss of memory particularly for recent events. The victim also becomes disoriented as to time or space, losing his way even on familiar streets. Anxiety increases with sudden changes in mood. In the third phase, the patient becomes severely disoriented and may suffer from symptoms of psychosis like hallucinations (hearing voices or seeing faces when no one is there) and paranoid delusions (A fixed irrational idea not shared by others and not responding to reasoned arguments).

[tex]\Large\textbf{Causes:}[/tex]

Alzheimer's disease is thought to be caused by the abnormal build-up of proteins in and around brain cells. One of the proteins involved is called amyloid, deposits of which form plaques around brain cells. The other protein is called tau, deposits of which form tangles within brain cells.

These Proteins are abnormal protein which are caused by the gene mutation which are present on the chromosome. Cases of early-onset Alzheimer disease which are caused by gene mutations can be passed from parent to child. This results in what is known as early-onset familial Alzheimer disease (FAD).

There are three single-genes on different chromosomes which are mutated to cause early age Alzheimer's disease. The three single-gene mutations associated with early-onset Alzheimer's disease are:

Amyloid precursor protein (APP) on chromosome 21. Presenilin 1 (PSEN1) on chromosome 14. Presenilin 2 (PSEN2) on chromosome 1._____________________________________Best Regards,'Borz'

what volume will 1.25 liters of carbon dioxide occupy at 50 degrees C if the pressure changes from 0.865 atm to 0.820 atm? show your work!

Answers

Answer:

V₂ = 1.32  L

Explanation:

Given data:

Initial volume = 1.25 L

Initial pressure = 0.865 atm

Final volume = ?

Final pressure = 0.820 atm

Solution:

The given problem will be solved through the Boyle's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

0.865 atm × 1.25 L = 0.820 atm × V₂

V₂ = 1.08 atm. L/ 0.820 atm

V₂ = 1.32  L

How can properties of matter be used to classify matter? Give an example other than copper.

Answers

Matter can be classified according to physical and chemical properties. Scientists can observe physical properties without changing the composition of the substance, whereas chemical properties describe the tendency of a substance to undergo chemical changes (chemical reactions) that change its chemical composition.

PS, love your pfp :)

The given question is answered as follows:

Any substance that has mass and that takes space is called matter. Atom is the smallest unit of a matter that cannot be further broken down. Matter exists in four major states: solid, liquid, gas, and plasma.

The physical and chemical properties are used to classify matter.They can be classified as either element or compound, phases can be heterogeneous, hoogeneous Physical properties can be observed to determined shape, volume.Chemical properties are helpful in determining their tendency to undergo chemical changes.

Examples: sugar- compound, crystalized, soluble in water.

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
