Explanation:

Bacteria play an important role in many genetic engineering experiments. Consider the space required to house larger animals. Bacteria are small and relatively inexpensive to maintain compared to most alternatives. Consider the time required to raise larger animals. Bacteria reproduce much more rapidly. Finally, consider the end-goal. Unlike experiments carried out on humans and animals, applications involvingmicroorganisms and their genetic modification do not cause pain and suffering as generallyunderstood. The ethical problems raised by genetically modified microorganisms (GMMs)therefore mainly related to the impact they have on the Earth's biosphere..
