Near a mid-oceanic ridge you can find... Question 16 options:

alternating bands of old rock and new rock.

bands of rock recording the magnetic field at the time of cooling.

stripes visible on the ocean floor.

alternate stripes of new crust and water.

bands of rock recording the magnetic field at the time of cooling

Explanation:

The ridge is a seafloor system of mountains that is formed by the plate tectonics and is found in places where the sea floor spreading that takes place and in the areas of divergent plate boundary.  The rate of seafloor spreading states the morphology of the ocean floor and due to the magma comes out to the surface from these ridges the rocks that form are aligned to their magnetic properties in the north and south position.

Essential for a scientist to do for credibility

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.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
