What is the time period from fertilization until birth?
usually 9 months
Fertilization and development normally occur in?
Fertilization occurs in the fallopian tube when a sperm cell fertilizes an egg cell. After fertilization, the zygote travels to the uterus where it implants into the uterine lining for further development. Embryonic development continues in the uterus until birth.
What is the time From fertilization until birth?
That depends on the species you are asking about. Different animals give birth after different periods of gestation.
When do the reproductive structures known as gonads appear?
The female ovaries are generally developed about 100 days after fertilization. The male testis do not descend into the scrotum until the ninth month of development although this sometimes occurs after birth.
What contains the embryo?
An embryo is a multicellular diploid eukaryote in its earliest stage of development , from the time of first cell division until birth, hatching, or germination . In humans, it is called an embryo until about eight weeks after fertilization
What prenatal stage of development in humans is the most rapid?
The embryonic stage, which lasts from fertilization until around 8 weeks, is the most rapid period of prenatal development in humans. This is when the major organs and systems of the body begin to form.
What does the embryo contain?
An embryo is a multicellular diploid eukaryote in its earliest stage of development , from the time of first cell division until birth, hatching, or germination . In humans, it is called an embryo until about eight weeks after fertilization
What are all changes that occur from the fertilization of the egg until death referred to as?
The changes that occur from fertilization of the egg until death are referred to as the lifecycle or life cycle. This encompasses all stages of development, growth, reproduction, and eventual death in an organism.
What is the type of fertilization in lions?
Lions exhibit internal fertilization, which means that the male lion transfers sperm to the female during mating. This process occurs during copulation, where the sperm fertilizes the female's eggs within her body. Following fertilization, the female lion carries the developing embryos in her uterus until she gives birth to cubs after a gestation period of about 110 days.
What time period does the embryonic stage of gestation covers?
How long is the embryonic period in humans?
Does embryonic development mean the same as fetal development?
No, embryonic development refers to the stage of prenatal development from fertilization to the end of the eighth week, when basic structures of the body are formed. Fetal development, on the other hand, refers to the stage from the end of the eighth week until birth, during which organs and tissues mature and grow in size.
What is the definition of gestation?
Period of time between fertilization and birth of an animal. Commonly called pregnancy.Gestation is pregnancy, carrying in the womb.Gestation is the process of carrying or being carried in the womb between conception and birth. Some animals gestation period lasts up to 113 days.
