why do some people not remember dreams

People who tend to remember their dreams also respond more strongly than others to hearing their name when they re awake, new research suggests.

To find out, researchers used electroencephalography to record the electrical activity in the brains of 36 people while the participants listened to background tunes, and occasionally heard their own first name.

When asleep, both groups

If there were no political party, then each and every candidate would be independent. Current strength of the Lok Sabha is 543. Imagine a situation when none of the 543 members can be brought to think alike on a particular issue. This would lead to a total chaos. An independent candidate would always be more interested in the specific needs of his constituency and would seldom think about the larger interest of the nation. ...

 why do you have to shock a pool

why do you have to shock a pool

Shocking a swimming pool, also known as super chlorination, is a very important process in pool management which every pool owner should understand and know how to do it, when to do it, which chemicals to use, and the best time of the day it should be performed. Most people don't think about shocking (super-chlorinating) until they have a cloudy swimming pool water or pool algae. But problems can be avoided if you do it regularly. Before I changed my non-saltwater (chlorine-based) pool to saltwater two years ago, I used to super-chlorinate regularly, but there is no single factor that determines how frequently it should be done. Basically, a chlorine-based pool needs more maintenance than a saltwater pool. Unless there is algae outbreak or contaminants such as oil and soil, a saltwater

 why do red blood cells lack a nucleus

why do red blood cells lack a nucleus

As explained in the previous answer, the RBC loses its nucleus only at maturity. The nucleus contains the DNA and which can in turn produce protein. No nucleus means - no protein/ mRNA synthesis. Also, obviously, the cell loses its capability to divide. Hemoglobin too is a protein. Knowing that it would lose its nucleus, hemoglobin is synthesized in the precursor stages of RBC. A mature RBC can not synthesize new Hb. Hence, the RBC keeps ready its store of enzymes and structural proteins (not only Hb, all proteins it would need for normal functioning) since it can not form new stuff once it has lost its nuclues. ...

 why was the battle of vimy ridge important to canada

why was the battle of vimy ridge important to canada

The assault on Vimy Ridge, the northern part of the wider battle of Arras, began at 5:30 am on Easter Monday, April 9, 1917. It was the first occasion on which all four divisions of the Canadian Corps attacked as a composite formation. The Canadian achievement in capturing Vimy Ridge owed its success to a range of technical and tactical innovations, very powerful artillery preparation, sound and meticulous planning and thorough preparation. At Vimy, the Canadian Corps and the British XVII Corps on their immediate southern flank had captured more ground, more prisoners and more guns than any previous British Expeditionary Force offensive. Vimy Ridge was a particularly important tactical feature. Its capture by the Canadians was essential to the advances by the British Third Army to the
