I dont freaking know
Before implantation, the embryo is nourished primarily through the uterine secretions known as uterine milk and the surrounding endometrial tissue. This phase occurs during the pre-implantation period when the embryo is still a blastocyst, floating in the uterine cavity. The blastocyst absorbs nutrients and fluids from the endometrium, which supports its growth and development until it can establish a more direct connection with the maternal blood supply after implantation.
The gestation period for a cat is typically around 63-65 days. During this time, the embryo develops into a fully-formed kitten inside the mother's womb. At birth, the kitten is ready to survive and navigate the world outside the womb.
Yes, marsupials are viviparous, meaning they give birth to live young. However, marsupials are unique in that their young are born in a very premature state and continue to develop in their mother's pouch.
They develop in the uterine horn, as the fetus grows, it will move into the uterus and then through the birthing canal at parturition.
The embryo that does not have an amnion is the human embryo. It is a membrane that covers the embryo when first formed. Mammals, reptiles and birds have this feature.
by placenta
the developing embryo is nourished by yolk
Its been nourished by the food the mother takes which is been converted into a liquid substance and later sent to the embryo through the placenta
The embryo in a seed gets its food from the endosperm or cotyledons within the seed. During germination, enzymes break down the stored food reserves in the seed to provide energy for the embryo to grow and develop into a seedling.
The reason why marsupial frogs have pouches is to keep the tadpoles until they develop into froglets.
In a pouch mainly.
The same way that a human embryo or any other mammalian embryo does.
The embryo develops in the uterus of the mother.
If there was an actual embryo, it was not a false pregnancy.
The embryo of a human develops in the uterus of the female body. The uterus provides a protective and nourishing environment for the embryo to grow and develop into a fetus.
incontinent, paralyzed, poorly nourished
