As we grow older, aches and pains can become a chronic part of life. But experts say it doesn't have to—and solutions are on the way.
During mitosis, a cell divides and splits its entire contents (including its chromosomes) between two daughter cells.As you can imagine, the cell cycle is a tightly regulated process. There are checkpoints throughout the cell cycle to ensure that everything is in order at the end of each ...
Unlike TDMA, which divides the transmission time into discrete time slots, CDMA networks assign a unique code to each user and spread the signal across the entire frequency band. But similar to TDMA, CDMA allows multiple users with CDMA phones to transmit and receive data concurrently without int...
Which types of cells would you expect to respond the fastest to the first exposure to bacteria? If a bacterial cell divides in every 20 minutes, how many bacteria will be formed in 2 hours? What type of blood cell protects against infection and attacks parasites and bacteria? What is microb...

Because the eggs are fertilized by two separate sperm, fraternal pregnancies have two completely separate zygotes (which is why they're called dizygotic twins). Each zygote separately fertilizes, divides, grows, moves through the fallopian tube, and implants separately in the uterus as two embryos...
People with polysomy have an extra copy of a chromosome. The problem may arise during meiosis, the cell division that produces sperm and ova, when a pair of chromosomes fails to separate completely, resulting in cells with either more or fewer than the normal number of chromosomes. Translocation...
to be closed, so that the domain on which remains holomorphic is still open. A typical class of examples are the functions of the form that were already encountered in the Cauchy integral formula; if is holomorphic and , such a function would be holomorphic save for a singularity at ...
Then is a degree Galois extension of with Galois group isomorphic to (with an element corresponding to the field automorphism of that sends to ). The intermediate fields are of the form where divides ; they are also Galois extensions, with isomorphic to and isomorphic to the multiples of in ...
It is the most common type. Under favorable conditions, each bacterium divides into two identical bacteria. The bacterial cells first acquire nutrition grow at their maximum size and replicate their DNA. The new replicated DNA called an incipient nucleus, migrates towards opposite poles. A transvers...
