3. What is a major physical characteristic that differs between members of Domains Archaea and Bacteria and members of Domain Eukarya? A. Members of Domain Eukarya are less complex than the members of Domains Archaea and Bacteria. B. Members of Domains Archaea and Bacteria are multicellular, and members of Domain Eukarya are usually single-celled organisms. C. Members of Domain Eukarya have cells with membrane-bound organelles, and members of Domains Archaea and Bacteria lack nuclei. D. Members of Domains Bacteria and Archaea have structures for making their own food, and members of Domain Eukarya lack these structures

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

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.
