The carrying of live young inside a female animal that gives live birth is called gestation. The length of the time spent in the gestation of one baby or one litter of young is called the gestation period. The time that a baby spends inside its mother (if its mother gives live birth) is called the gestational age.
What else can I help you with?
The period during which mammals develop inside the uterus is called?
Gestation.
Why do offspring develop inside their mother?
Placental mammals.
Are dogs marsupial monotreme or placental?
Yes. The dog keeps the young inside the body until the baby can function independently.
Where do most mammals grow before they're born?
Most mammals are placental mammals: they develop in a placenta before birth. Marsupials also develop in a placenta, but they are delivered much earlier and the placenta is less developed. Monotremes develop within an egg, which is kept inside the mother for some time before it is laid. It hatches several days later.
What is an organ in most mammals that provides nourishment to the young before birth?
The placenta. Placentas are found in female placental mammals (most mammals are placental mammals) inside the uterus and are a passageway by which nutrients flow from the mother's bloodstream to the baby's bloodstream and by which waste products flow from the baby's bloodstream to the mother's bloodstream.
What kind mammals carry offspring to term inside the body?
Placental mammals, also known as eutherians, carry their offspring to term inside the body. They are different from the marsupials, which give birth to immature young which continue their development in a pouch, and monotremes, which are egg-laying mammals.Placental mammals include all members of the canine family, felines, equines, bovines and other livestock, camels and many other mammals.
Is a lion a placental mammal?
Yes, a lion is a placental mammal. Placental mammals are characterized by giving birth to live young that have developed inside the mother's uterus with the aid of a placenta. Lions give birth to live cubs after a gestation period.
Why can't humans lay eggs?
Humans are placental mammals, meaning that they develop with the embryo attached to a placenta that allows it to exchange waste and nutrients with the mother. The placenta would not be able to function inside an egg.
Do mammals have internal or external development?
internal. They develop inside the womb
Are gorillas in the order Eutheria?
Yes. A gorilla nourishes its baby inside a uterus via an umbilical cord and the baby is born relatively well-developed. All placental mammals, or eutherian mammals, do this.
Where do placental mammals live?
Placental mammals are mammals that give birth to fully developed live young, such as like humans, for instance. They are classed within the group of animals known as eutherians. Dogs, cats, livestock, rodents, giraffes, rhinoceroses, etc, are all placental mammals. This is opposed to the monotremes, which are egg-laying mammals (platypuses and echidnas) or marsupials (kangaroos, koalas, wombats, etc), which give birth to very undeveloped young that must complete their development attached to a nutrient-supplying teat, usually in the mother's pouch.
Does a foal develop inside a horses stomach or by some other means?
A foal develops inside a female horses uterus. Horses are placental mammals which means that, after conception, the zygote (fertilized egg) attaches to the uteran wall and then develops. After about 11 months, the mare (female horse) gives birth to a relatively well developed baby, the foal.
