What is Alzheimer’s Disease and how is it caused from the chromosomes?
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'3. How are frog eggs being used in research involving human cells?

You are looking for a rare plant, the Nirnroot. You know when you hear the song of the plant it is close. This plant is known for its hybrid properties, as it is both a antiseptic and is capable of healing any injury when you use the juice from its leaves. While you were not able to find any in the wild, an old farmer informed you to cross a Nirn Flower with a Dale Root to create the famous plant. Given that all Nirnroots are incompletely dominant, what is the genotype for a Nirnroot?Immersive Reader

what elements can be found in the structure of DNA if DNA is composed of nucleotides?
Answer:
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.

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

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!
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
