Answer: correct: The CAP-cAMP complex unbends the DNA loop, thereby allowing binding of RNA polymerase
Explanation:
The CAP-cAMP complex unfolds the DNA loop, allowing the binding of RNA polymerase. The catabolite activating protein, when bound with cAMP, is known to stimulate the transcription of the operon lactose genes, being necessary for the reaction RNA polymerase
The hydrosphere (water on the surface of the planet). This includes oceans, seas, rivers, streams, lakes and ponds.
<u>Answer:</u>
When cells are in an <u>isotonic</u> solution, they are maintaining homeostasis.
<u>Explanation:</u>
"Homeostasis" is the process to maintain a stable and relatively constant internal environment. In addition to temperature it is maintained for many other factors too. "Isotonic solution" comprised of two solutions having the similar osmotic pressure across a semipermeable membrane.
Such solution maintain homeostasis of a cell via diffusion process. As in such solution the overall concentration on both sides of the membrane remains equal. The cell membrane command the movement regrading entrance and exit of anything in cell, the membrane control water and ion transport because of its phospholipid bilayer structure.
