The law of conservation of mass states that when chemical reactions take place in a closed system,matter can never be created or destroyed but instead is simply transformed.
Artificial Selection is a form of selection in which humans actively choose which traits should be passed onto offspring. Humans have used selective breeding long before Darwin's Postulates and the discovery of genetics. Farmers chose cattle with beneficial traits such as larger size or producing more milk, and made them breed; and although they may have known nothing about genes, they knew that the beneficial traits could be heritable. The farmers selected for certain traits in their cattle and probably noticed that the offspring were becoming more and more productive with each generation. Scientists study these traits and spend a lot of time calculating how heritable these traits can be. The more these traits are expressed in the offspring (i.e. size, milk production, etc), the more heritable these traits are said to be. Hunting is also a form of artificial selection, with the genes that humans "want" (i.e. - the biggest buck with the most points, the largest fish, etc.) being removed from the gene pool, allowing the less "wanted" genes to pass on to the next generation by increasing their odds of mating when compared to the hunted specimens.
Hope this will help.
While conducting a Repetitive
Transcranial Magnetic Stimulation (rTMS), coils are characteristically
placed over the prefrontal cortex and then electric current is delivered. Since
1985, rTMS, a form of brain stimulation therapy has been in use for the treatment
of depression and anxiety.
