Question

Quizplus · Accepted Answer

Fertilization is the moment at which the ovum and sperm unite.

Answer: D
 The zygote is the product of fertilization, when the sperm and egg unite and form a genetically unique individual.

Answer: M
 Implantation is the process by which the blastocyst, a ball of cells that has formed after several rounds of cell division, implants in the wall of the uterus and begins to grow.

Answer: F
 The blastocyst is a stage in embryonic development when the ball of cells has formed into a hollow ball with an inner cell mass that will go on to form the embryo proper.

Answer: E
 Organogenesis is the process of forming specific organs from the germ layers during embryonic development.

Answer: J
 The primary germ layers are the three layers of cells that form during embryonic development and give rise to all the tissues of the body.

Answer: K
 Histogenesis is the process of forming specialized tissues from the generic tissues of the primary germ layers.

Answer: L
 Embryology is the study of the development of embryos and fetuses.

Answer: C
 A neonate is a newborn baby, typically the term is used for babies up to one month old.

Answer: I
 Senescence refers to the process of aging, both at the cellular level and in the organism as a whole. It is not directly related to development, although it does have an impact on the aging of tissues and organs.
