<span>Central dogma by Crick is explaining how a gene is translated. It involves transcription and translation. Transcription is copying the message of DNA to mRNA. This message is translated in the cytoplasm by ribosomes with the help of tRNA to syntheise proteins which are basis of every metabolic reactions. This is an inference based on observations. For him it was found reasonable to infer the message should be carried from DNA to cytoplasm.</span>
McBossatronio,
The answer is the first option "all systems work together to stabilize the body." Homeostasis is the internal conditions that all living things have basically meaning how the body keeps cool during hot weather, or warm during cold weather. You ever wonder why you sweat when it's hot, or shiver when it's cold that's your body keeping warm and cool which helps all your systems work together.
Hope this helps!
