Number the events (1-4) based on the order that they happened, with 1 being the first thing that happened and 4 being the last. Magma cut into the red-brown rocks and solidified to form glasslike rocks. Red-brown rocks with sand-sized rock grains were deposited horizontally. Rocks composed of gray clay flakes with crystals of minerals were deposited horizontally. Rocks made of shell and skeletons of marine organisms were deposited horizontally

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

the backbone of the dna and rna compound is sugar phosphate.
