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
Following fertilization by the sperm cell, the egg cell undergoes what is known as a cortical reaction, which alters the egg cellâs zona pellucida â the outer shell of the egg -- and prevents more than one sperm cell from penetrating the eggâs cell wall, which is a condition known as polyspermy.
