Ans-3) No. pierced ears is not a trait; it's a procedure which is performed. If a mother had a fingure amputated, you would not expect her children to be born without one.
Ans-4) This phenomena could take place because offsprings which haven't achieved maturity have a very weak immune system. There environment could be another factor.
Ans-5) The experiment conducted by
Stanley L. Miller and Harold C. Urey in 1953. they assembled an atmosphere similar to that thought to exist on early earth (this had molecules like Ammonia, Methane and hydrogen sulphide, but no oxygen) over water. This was maintained at a temperature just below 100°C and sparks were passed through the mixture of gases to simulate lightning. At the end of a week, 15% of Carbon (from Methane) had been converted to simple compounds of Carbon including amino acids which make up protein molecules.
hope it helps you,
