Roughly two weeks. The fertilization of a cat embryo takes a few steps to develop.
Yes, elephants have a long gestation period of about 22 months, which is the longest of any land animal. This extended development time allows the calf to be born at a more advanced stage of physical and cognitive development compared to many other animals.
If a setting hen gets off the nest and the eggs get cold, the embryos inside the eggs could die. The hen's body heat is crucial for keeping the eggs at the proper temperature for development, so it's important for her to spend most of her time on the nest.

At 16 weeks, a human embryo is about 4.6 inches (11.6 centimeters) long. It is about the size of an avocado and is starting to develop more defined features like facial expressions and fingernails.
It takes around 9 months x
No. The uterus is the only organ capable of supporting the implantation of the blastocyst, which gives it the oxygen and nutrients it needs to develop into an embryo.
