Eugene is listing the colors of the various atoms within a molecule what color would he use to show carbon

The carbon must be represented by the color black or white.

Explanation:

Ideally, represent the elements with the color closest to their actual color. In all its allotropic forms, carbon is in a solid physical state, but other physical characteristics vary from structure to structure. The color of the carbon varies with the organization of its molecules, in which case the diamond's carbon is transparent and the graphite carbon is black. For this reason the ideal would be to represent carbon with a black or white color.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
