Fetal development, by definition, takes place during the fetal period while in the uterus. In an ectoptic pregnancy, fetal development takes place outside the uterus but still within the female's body; this type of pregnancy is generally terminated when it is identified because the female cannot carry the fetus to term and there is a major risk of death to the female.
What else can I help you with?
What tells cells to differentiate during embryonic development?
The inheritance of an organism tells cells to differentiate during embryonic development.
What is the development at an early stage for humans pets and petunias called?
The development at an early stage for humans is called embryonic development, for pets is called embryonic or fetal development, and for petunias is called seed germination and seedling development.
During embryonic development of animals tissue layers form This process of embryonic tissue development is called?
The process of embryonic tissue development where tissue layers form during animal development is called gastrulation. This process involves the rearrangement and differentiation of cells to create distinct layers that will give rise to different body structures and organs.
When do the gonads develop in embryonic development?
The gonads develop around the sixth week of embryonic development. Initially undifferentiated, they differentiate into either testes (male) or ovaries (female) depending on the presence or absence of certain genes.
What is associated with pre-embryonic development?
Pre-embryonic development is associated with processes including fertilization, cleavage, and formation of the blastocyst. During this stage, the zygote undergoes division and differentiation to form the blastocyst that will later implant into the uterine wall for further development into an embryo.
What does the neural tube develop into during embryonic development?
The neural tube develops into the brain and spinal cord during embryonic development.
What tells cells to differentiate during embryonic development?
The inheritance of an organism tells cells to differentiate during embryonic development.
What type of embryonic development do porifera have?
Raskolnikov
What is the development at an early stage for humans pets and petunias called?
The development at an early stage for humans is called embryonic development, for pets is called embryonic or fetal development, and for petunias is called seed germination and seedling development.
How Is Embryonic Growth similar to fetal development?
Compare embryonic growth and fetal development in single and multiple pregnancies, including the incidence of complications and infant mortality.
Why is the process vital to the embryonic development of a fetus?
Nutrients
What is the African elephant embryonic development?
It is fertilized and then poops.
How many cells do you start as in the process of embryonic development?
During the process of embryonic development, you start as a single cell called a zygote, which is formed when a sperm fertilizes an egg.
How can embryonic development be used in evidence for evolution?
Embryonic development can provide evidence for evolution by showing similarities in early stages of development across different species. These shared characteristics suggest a common ancestry and evolutionary relationships between organisms. By studying embryonic development, scientists can trace evolutionary changes and genetic relationships between species.
Which sequence represents the order of some events in human development?
Conception, embryonic development, fetal development, birth.
The resumption of growth after a period of arrested embryonic development is?
germination
Do vertebrates have a notochord during early embryonic development?
True
