Question: Grasshoppers show variation in back-leg length, Grasshoppers with the longer back legs have a larger jump range and are more likely to
survive when encountering predators. Given the following data, determine the standard deviation of grasshopper back-leg length to the
nearest hundredth.

nucleus

would be most reasonable answer tbh

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
