Why does a foetus not drown?
The foetus gets oxygen through the mother's umbilical cord:
The fetus receives its oxygen supply across the placenta, to which oxygen is delivered by maternal blood. The amount of oxygen delivered to the placental site is determined by the magnitude of blood flow and the oxygen content of uterine arterial blood. Transfer of ...
Currently no, but there is work in progress that will allow extremely premature babies to be grown in artificial uteri. It has so far worked well for baby goats.
8th Month is ~ 32 Weeks, pregnancy is usually ~40 weeks
Up to 15 weeks' gestation, suction-aspiration or vacuum aspiration are the most common surgical methods of induced abortion. (Healthwise, 2004) Manual vacuum aspiration (MVA) consists of removing the fetus or embryo, placenta, and membranes by suction using a manual syringe, while electric vacuum ...
Taking a partly developed foetus out of the mother? This is currently not an available method.
However, there are methods out there for the problems you described:
One method allowed in the UK is called a "three-parent baby" and the following guardian article explains it fairly well:
The procedure replaces a small amount of faulty DNA ...
Very rarely, The AB father plus O mother scenario you describe can cause a disease:
More commonly, Rh-positive father plus Rh-negative mother can cause a disease:

You are still very early in your pregnancy, so it is likely that everything will be fine if you take measures to stop smoking now. I would highly suggest meeting with your OBGYN to discuss safe methods for smoking cessation during pregnancy. The earlier you quit, the better off your baby's development will be. Prenatal smoking has been associated with ...

Meredith Carlson Daly studied this and commented saying;
"Researchers at Northwestern University School of Medicine reviewed 10 published research studies on the practice of placentophagy. They found no data to ...
Different cell lines exist for different reasons, depending on the cell type and their properties they are useful for different experiments.
HEK-293 - Embryonic Stem Cells - Female
WI-38 - Fibroblasts derived from lung tissue - 3 month old female
MRC-5 - Fibroblasts derived from lung tissue - 14 week old male
Embryonic stem cells are totipotent, meaning ...
In addition to @Andrew's answer about technical limitations, consider that searching for "HEK-293" for example on Google Scholar returns over 120,000 results.
The thousands and thousands of studies using these cell lines provides an extensive institutional body of knowledge. There are many foundational studies done to understand these cell lines ...
No, first you should go throw an IVF process (egg retrieval process and a fertilization by sperm in a lab). Once the embryos are created, after 3 or 5 days they can be transferred to a gestational carrier who will carry the baby until the birth. This process is called gestational surrogacy. In gestational surrogacy, the surrogate is not genetically linked to ...
