What else can I help you with?
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
How do you called an undeveloped baby?
An undeveloped baby is commonly referred to as an embryo during the early stages of development, typically up to eight weeks after fertilization. After this period and until birth, it is called a fetus. In a broader context, the term "unborn baby" can also be used to describe a developing baby in the womb.
Do camels have embryo tic development?
Yes, camels undergo embryonic development similar to other mammals. After fertilization, the fertilized egg implants in the uterus, where it develops over a gestation period of about 13 to 14 months. This process involves the formation of various structures that support the developing embryo until birth. Ultimately, camels give birth to a single calf, which is well-developed and can stand and walk shortly after delivery.
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.
The period of the fetus lasts for how long?
The fetal period lasts from the end of the eighth week of pregnancy until birth, typically around 40 weeks gestation. During this time, the developing fetus undergoes significant growth and maturation of organs and systems. This phase follows the embryonic period, which lasts from fertilization until the end of the eighth week.
What is the differences between embryo and a foetus?
An embryo is the early stage of development in a multicellular organism, specifically from fertilization until about the eighth week of gestation in humans. During this period, the basic structures and organ systems begin to form. After the eighth week, the developing organism is referred to as a fetus, which continues to grow and mature until birth. The transition from embryo to fetus marks a significant phase in development, characterized by more complex growth and differentiation of tissues and organs.
