In accordance with the Theory of Evolution, Natural Selection is mechanism through which the evolution happens. Advantageous traits survive the longest and leave the most offspring, a process termed as Natural Selection. Select an animal species. Your goal is to explain the way where an evolutionary change might takes place […]

Q. A DNA-like molecule is isolated from the frozen remains of alien life-forms found beneath the Martian North polar ice cap. The molecule is a double stranded polymer whose monomeric subunits are collected of glycerol, phosphate and nitrogenous bases, of which four kinds were found. The bases in this “glyceronucleic […]
