Bipedal motion in humans leads to a narrower pelvis compared to quadrupedal animals, which complicates childbirth. The upright posture requires a more complex arrangement of the pelvic bones, making the birth canal constricted. Additionally, the larger brain size of human infants necessitates a larger head, further challenging the birthing process. This combination results in greater difficulty and often more prolonged labor during childbirth.
Friction is the force that can make sliding difficult, as it opposes the motion of two surfaces sliding against each other.
It's an evolutionary compromise between being bipedal and having larger brains. Other animals have a straight shot out the birth canal where as human newborns must make twists and turns to get that large brain out of that bipedal pelvis.
Continuing to smoke cigarettes can be extremely harmful to the developing fetus and complicate the process of childbirth. Also, chemical sensitivity and "morning sickness" common to pregnancy can make the act of smoking unpleasant, even sickening.
I am not a medical professional, but I would always advise natural childbirth at a hospital rather than home delivery. If you have any complications then it is more difficult to treat at home, whereas in the hospital they will abide by your wishes of natural childbirth and make it as safe as possible for you and your baby! Congratulations! Good luck on your decision!
False. Friction is a force that resists motion, so it can make work more difficult rather than easier. Minimizing friction can help make work easier.
Females most likely prefer to give birth at home other than a hospital because they are in their own comfort zone and with their family but being away from home can cause stress and make this more difficult.
God makes motion, not a person!

Newton's first law of motion categorizes any force affecting the motion as an external force. Friction being an external force, negates its presence as an integral force of a motion. Hence friction cannot be used to observe first law of motion.
Velociraptors had a unique hip structure that allowed for a greater range of motion and agility. Their hips were more bird-like, resembling those of modern birds, which facilitated bipedal locomotion. This adaptation contributed to their speed and ability to make quick turns while running. Additionally, their pelvic structure supported their carnivorous lifestyle, enabling them to hunt effectively.
Yes, it is difficult to make significant changes.
The vagina always stay the same. The only thing that can change that would be childbirth.
