Question: Answer the following question given this paragraph: In prokaryotes, a combination of activators and repressors determines whether a gene is transcribed. As you know, prokaryotic organisms are fairly simple organisms with much less DNA. Prokaryotic genes are arranged in operons , a region of DNA with a promoter, an operator , and one or more genes that encode proteins needed to perform a certain task. To maintain homeostasis (and survive), the organism must quickly adapt changing environmental conditions. The regulation of transcription plays a key role in this process. Q: In order to survive and maintain what state, an organism must quickly adapt to changing environmental conditions? Choices: - ketosis - acclimatization - regulation - homeostasis A:
Answer:
homeostasis
