deficit in language comprehension or production due to brain damage, usually on the left hemisphere (similar deficit not usually found with damage to the right hemisphere)
The only exception is sperm or eggs which are produced by a different type of cell division called ________. meiosis. fertilization. sperm and egg unite to form a single cell called the zygote which contains chromosomes from the sperm and egg. The zygote undergoes mitosis to begin the development of the embryo which eventually becomes a baby
The other sperm die within 48 hours. The fertilized egg is now called a zygote. The depolarization caused by sperm penetration results in one last round of division in the egg's nucleus, forming a pronucleus containing only one set of genetic information.The pronucleus from the egg merges with the nucleus from the sperm.Once the two pronuclei merge, cell division begins immediately. The dividing zygote gets pushed along the Fallopian tube. Approximately four days after fertilization, the zygote has about 100 cells and is called a blastocyst.When the blastocyst reaches the uterine lining, it floats for about two days and finally implants itself in the uterine wall around six days after fertilization.he pronucleus from the egg merges with the nucleus from the sperm. Once the two pronuclei merge, cell division begins immediately. The dividing zygote gets pushed along the Fallopian tube. Approximately four days after fertilization, the zygote has about 100 cells and is called a blastocyst.
