Comparing two-component signal transduction systems and phosphorelay systems, . Multiple Choice the two processes differ only in that phosphorelay systems are more widespread than two-component signal transduction systems two-component signal transduction systems mediate the transfer of a single phosphoryl group from a sensor kinase to a response regulator, whereas phosphorelay systems transfer multiple phosphoryl groups between a series of proteins two-component signal transduction systems mediate the transfer of multiple phosphoryl groups between a variety of sensor kinases, whereas phosphorelay systems transfer a single phosphoryl group to a response regulator phosphorelay systems mediate the transfer of a single phosphoryl group from a sensor kinase to a response regulator, whereas two-component signal transduction systems transfer multiple phosphoryl groups between a series of proteins

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.

well, i believe that the answer is 2. : 3

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate
