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?
Are tigers a placental mammal?
Yes, tigers are placental mammals. They belong to the order Carnivora and are part of the family Felidae. As placental mammals, tigers give birth to live young that develop inside the mother's uterus, receiving nutrients through a placenta during gestation. This reproductive strategy is characteristic of most mammals in this group.
The period during which mammals develop inside the uterus is called?
Gestation.
Why do offspring develop inside their mother?
Placental mammals.
Which is the difference between the three mammal groups?
The three main groups of mammals are monotremes, marsupials, and placental mammals. Monotremes, like the platypus, lay eggs and produce milk but lack nipples. Marsupials, such as kangaroos, give birth to underdeveloped young that continue to develop in a pouch. In contrast, placental mammals, including humans, have a complex placenta that nourishes the developing fetus during a longer gestation period inside the womb.
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.
