Does nature or nurture (hereditary or environment) influence the development of one's identity more? Scientifically, what are the arguments presently for each stance?

It's my understanding that Adaptation occurs usually through more prominent genes in an organisms' population drift or mutate. How does a trait like camouflage occur, when the experience that the organism actually engages in to warrant said camouflage in turn kills it. In other words; How can an organism pass on a trait that it usually doesn't survive to pass on.

Does menthol kill spermatozoa or is it neutral... or maybe even helps it somehow?? (I don't know - I don't have a microscope, and Internet says nothing about it specifically so I ask) Now - someone would say "Well - you know - it depends on concentration!" - so - here - for example: say you have a menthol tablet for sore throat say 160mg in weight, containing 2mg of menthol, 0.1mg of sodium usnat and sorbitol artificial sweetener - would it kill spermatozoa?

Hello Have dinosaurs existed with men ??? Is there any scientific evidence ??? and , someone told me that using the Radiocarbon isn't beneficial and is not accurate while talking about dinosaurs >> and please see this video about the co-existence >> Thanks

1.technically composition of fruits like mango's with which we are making pickle contains water.what is difference between that water and water which we are adding? 2.If you say that the difference is presence of microbes, we can preserve pickles for years if we add large quantity of salt to it.when salt has capacity to sterilize pickle by dehydrating microbes, it should be able to take same action on microbes present in added water.but practically pickle spoils.why??

I am isolating RNA from cartilage, which is notoriously difficult due to the low cell count and stiffness of the tissue. The eventual application is q-PCR analysis. We use a hybrid TRIzol/RNeasy protocol that goes something like this: homogenize with trizol, three extractions with TRIzol/BCP Isopropanol precipitation Resuspend in 150uL RNAse free H20, mix with equal volume 80% EtOH Apply to QIAgen RNeasy spin column and clean according to directions. Elute in volume of 30 uL, running eluate through membrane twice to increase RNA yield On a good day, average yield is 30-40 ng/uL, with a 260/280 of 1.8+, and 260/230 of 1.3 ish. On a great day, can get as muc…

Was lamarckian inheritance hypothesis wrong? he said the giraffe's long next develop over generations when its parents keep on stretch their neck to reach for high leaves. but then as we know, an individual's phenotype may change as a person develop large muscle after muscle training. but a child of muscle-bound parent is not born muscle-bound.offspring inherit genes, but not parents phenotypic changes. Does this mean Lamarck was wrong? so if he was wrong. what traits goes to just change in phenotype and what goes to change in genes. how is it decided. for example, the fishes wants to catch prey on land, in theory of evolution, legs were slowly grown over …

can some one explain to me what is the relationship between enzyme activity and rate of reaction?
