Answer:
So the mnemonic that I know is SNOW DROP. Southern=DNA, Northern=RNA, O=O, and Western=Protein. The question asks, "Which technique CANNOT be used to analyze gene expression?" and the answer is Southern because it is a "techniue used to detect a particular sequence in a sample of DNA."
I think the correct answer from the choices listed above is the first option. Regulatory proteins of the cell cycle help maintain homeostasis by controlling <span>the cycle by signaling the cell to either or delay the next phase of the cycle. Hope this answers the question.</span>
For the answer to the question above, the peripheral nervous system governs <span>all structures outside the brain and spinal cord. Peripheral nerves branch from the spinal cord through the foramen transversarium of each vertebrae. I suppose the structure it would not affect is the brain itself since cranial nerves are responsible for brain activity. Also, the spinal cord would also be unaffected since it is just a cylindrical bundle of nerve fibers that allow the connection of the peripheral nerves to the brain.</span>
Answer:
D. In an ocean heated by volcanic activity
Explanation:
Most of Earth was covered in water, early organisms weren't evolved enough to walk on land at the time. There are some organisms that feed off of volcanic activity and use it as an energy resource and would adapt to the heat.
<em>"Hot spots create volcanoes on the seafloor. If these volcanoes rise above sea level to become islands, and if they occur in tropical waters, coral reefs will form on them. Since the volcanoes are cones, the reef forms in a circle around the volcano."</em>

<em>"Discovered only in 1977, hydrothermal vents are home to dozens of previously unknown species. Huge red-tipped tube worms, ghostly fish, strange shrimp with eyes on their backs and other unique species thrive in these extreme deep ocean ecosystems found near undersea volcanic chains."</em>
