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

Answer the following question given this paragraph: Why does it snow instead of rain? Air temperature determines which type of precipitation falls. Rain falls if the air temperature is above freezing (0 C or 32 F). Frozen precipitation falls if the air or ground is below freezing. Frozen precipitation may fall as snow , sleet , or freezing rain . Below, you can see how the different types form ( Figure below ). Q: What determines which type of precipitation falls in the atmosphere? Choices: - air density - moon phase - time of day - air temperature A:
(Answer)
air temperature
