7. Which of the following organisms are prokaryotes? a. portabella mushroom
B. Rose

C. butterfly

D. e.coil

Please hurry

D. E. Coli

Explanation:

Prokaryotes are single-celled organisms that lack nuclei and membrane-bound cell structures. The two domains that are classified as prokaryotic are Eubacteria and Archaea.

E. Coli is a bacteria, belonging to the domain Eubacteria, therefore it is a prokaryote.

To eliminate the other answer choices, portabella mushrooms, roses, and butterflies are all eukaryotic organisms. (Eukaryotes are all living things and fungi, besides eubacteria and archaebacteria.)

this protocol describes a detailed procedure for intracellular flow cytometry staining.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
