Answer	—	A: Plausible cause of a family only giving birth to females? Consider: there are conditions that are passed on by X-linked recessive inheritance. The most famous is haemophilia. Here's how it works: mutation BadNews is recessive, and carried on the X chromosome. The mother is a carrier. A daughter would get a healthy X chromosome from the father, and either a ...

Question	—	How would seasons work on a moon orbiting a gas giant orbiting a star? Let us assume a sufficiently earth-like moon, like Europa. It orbits a gas giant. The whole setup is within the star's goldilocks zone, so the moon is theoretically habitable. 'Day' is one rotation of the moon around itself, 'month', for the sake of the argument, is one rotation of the moon around i... (more)	—	over 6 years ago
Answer	—	A: Is this a viable/realistic imaginary species? There is a major problem with this species: a plant needs nutrients to grow. Not just sunshine and CO2, but water, minerals, proteins etc. Normally, those would be acquired from the soil and/or from symbiont microorganisms. If, instead, those nutrients come from the carrying animal, then the carrying... (more)	—	over 6 years ago
Answer	—	A: How to differentiate between elves and men You could make a different colour scheme for your elves: just as humans are all shades of brown (from pinky-beige "Caucasian" to dark), with pink or yellow undertones, your elves could be different shades of green. Or blue. Then your half-elves could be some sort of mixed colour, or they could have p... (more)	—	over 6 years ago
Answer	—	A: How long would life on Earth survive without any animals? If all the fauna on earth has been killed (vertebrates and invertebrates), there are no pollinators left. Which would kill off many plants. (That is, make them unable to reproduce, so once they die, there won't be any more of them.) The plants that are wind-pollinated will survive. There will still ...

Answer	—	A: What would be needed for the entire planet to have a polar climate? If a planet is far enough from its star, it will be cold, water will be frozen etc. To have plants, you'd need liquid water for at least part of the year (something like the tundra, at least.), or you'd need liquid seas where you'd have algae. If you don't have plants, you can't have all the higher o... (more)	—	almost 7 years ago
Answer	—	A: Virtual Reality and Physical Trauma Like Cort Ammon says, it would depend on how your VR functions. The brain has mechanisms that prevent what's going on in your brain to affect your body in any way: that's what happens when you're dreaming. While dreaming, you can believe yourself running, falling, getting hurt, even dying. None of th... (more)	—	almost 7 years ago
