tatiyna

Answer:

See explanation.

Explanation:

The initial days and even weeks of pregnancy may happen without a woman being aware of the pregnancy. Even though the baby grows quickly, it starts out as just a fertilized egg. So it takes a while to be noticed. And there is plenty of room at first.

But with an ectopic pregnancy, the baby attaches, instead of in the uterus, outside of the uterus. In most cases, the baby attaches inside the fallopian tube. Outside of the uterus is not designed to provide support and space for the baby. As growth occurs, it can cause severe problems. This is dangerous and can cause bleeding, pain, and possibly shock of the woman's condition is not identified and treated.  

Hope this helps! Have an awesome day!! :-)

The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution

This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.
