which of the following structures is not found in
bacteria?

Organelles

Explanation:

Bacteria are a type of biological cell that has an Intracellular or internal structure.

Structural components are located in bacteria, and we can find there DNA, ribosomes, cell wall and membrane, surface layer and cytoplasm.

In bacteria structural components aren't found 'The nucleus' and that is a membrane-enclosed organelle.

producers: apple trees, potatoes, carrots, grains, acorns, cabbage, grass, corn, lettuce

consumers: deer, mice, rabbits, chickens, squirrels, horses, worms, cows

predators: eagles, frogs, wolves, owls

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.
