A fetus stays alive by obtaining nutrients and oxygen through the placenta, which connects it to the mother’s bloodstream. The placenta also facilitates the removal of waste products from the fetal blood. Amniotic fluid surrounds the fetus, providing cushioning and a stable environment for development. Hormones produced by the mother support the pregnancy and fetal growth.
At 5 weeks it's a embryo not a fetus. it just grows and can not feel, hear or is aware of anything yet.
Around day 40 of a pregnancy, you can distinguish between a chimpanzee fetus and a human fetus based on their physical characteristics and developmental stages. Chimpanzee fetuses have a shorter gestation period compared to human fetuses.
They have all the characteristics of life.
at 4-5 months
A fetus develops its sex characteristics during the first trimester, specifically around the seventh week of gestation. If the fetus has XY chromosomes, it will typically develop male characteristics, while XX chromosomes lead to female characteristics. External genitalia become distinguishable by the end of the 12th week. However, the visible assignment of sex is often made based on these anatomical features during an ultrasound, typically conducted around 18-20 weeks.
Wouldn't know unless there was more detail. There are many circumstances that can cause a miscarriage or a birth ending in stillbirth prematurely.
