Oral rehydration solutions that contain both salt and glucose are highly effective in treating severe dehydration caused by diarrhea and vomiting. However, glucose or salt alone are not effective. This is because water passively follows
A. sodium and glucose, which are cotransported across the gastrointestinal epithelium.
B. glucose and sodium, which are transported by facilitated diffusion.
C. glucose, which provides the energy for the active transport of salt.
D. ATP, which is required to transport sodium unless glucose is available for cotransport.
E. glucose that is broken down quickly in the mouth by saliva and cotransported with salt via diffusion across the epithelial cells of the oral cavity.
A. sodium and glucose, which are cotransported across the gastrointestinal epithelium.

A gene that undergoes rho-dependent termination has a mutation in the rut site. How will this influence transcriptional activity?
A. Transcription will terminate normally as Rho termiantion relies on the rut site to enhance termination; it is not essential for termination B. Transcription will stop immediately because RNA polymerase will sense there is a mutation C. Transcription will continue until another termination sequence, either Rho dependent or independent is reached D. There will be no transcription initiation
