Please help! Describe the four conditions required for natural selection to occur and explain how evolution is a consequence of the interactions of these factors

Hi, Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.

well we can't tell you because we cant see the time give a screen shot or something.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
