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
Only one sperm nucleus enters the egg. The haploid sperm nucleus fuses with the haploid egg nucleus, and a fertilised egg or diploid zygote is formed. As soon as the sperm has entered the egg, the membrane of the egg changes so that no other sperm can enter. The remaining sperms, which do not fertilise the egg, eventually die. The cilia lining the oviduct sweep the zygote along the oviduct. Peristaltic movements also help move the zygote to the uterus.
