-stange hyraglyphical type tracks that resembled tree branches coming of the other branches. In case the slide was contaminated I did a second take of the experiment and had the same response. When I took a sample from my wife, she didn't have them. They seem to form over minutes, maybe as it dries. It maybe crystaline in nature I don't know, does anyone know what I am describing here. What is this stuff, its made me concerned.

In mitosis, replication of chromosomes precedes each cell division.
In meiosis, two cell divisions take place without a replication of chromosomes between them. What is the significance of this difference?
thanks :)

How does the # of chromosomes in each newly formed cell compare to the # of chromosomes in the parent cell?

Also, are these newly formed cells diploid or haploid?
Thanks :)

I wanna ask a question..

In the blood ABO test....

as we know blood type AB is the universal recipient while blood type O is universal donor....and if we dindt donate the or recieve the suitable type of blood our blood will agglutinate and it would be fatal.

Ermmm...once there was a question in my reference book.

If blood of group AB is mix with the blood group O in a test tube,will it agglutinate since:-

a) If a person donate blood O to AB it would be fine
b) but if blood group AB is donated to blood group O than it would agglutinate..

this is very confusing can some1 help me on how to define whether it will agglutinate or not if its in the state of mixture in a test tube..

thx i need this in my exam tommorow

I was watching a documentary about martial arts and the physics behind them. They dealt with reflex speed and proved that a punch (Wushu martial arts) was 4x the speed of snake strike. They also said that the speed of the signal running from the brain to the fists was 225m/s. Other than Gatorade (electroltyes), can you take a drug to increase reflex speed?
