The seismic traces recorded at station A and station B indicate that station A is further from the earthquake epicenter than station B because the ground movement detected at B was greater than that detected at A, with seismic waves more frequent and less frequent respectively.
<h3>Seismograph</h3>
A seismograph is a device that detects ground movements, including those generated by seismic waves. It consists of the basic sensor of the seismographic instruments of which the seismograph and the seismoscope are part. These movements are then recorded in seismographs, which have been plotted graphs called seismographs.
<h3> Propagation speed</h3>
Seismic station A is located 5,400 kilometers from the earthquake's epicenter. How long would it take for the first S wave produced by this earthquake to reach seismic station A? The propagation speed of this type of waves varies with the medium in which they propagate, with typical values of
- 330 m/s in air
- 1 450 m/s in water
- and 5 000 m/s in granite.
They are not as destructive as S waves or the surface waves that follow them. The propagation speed of these waves is, in general, slightly less than twice that of S waves.
With this information, we can conclude the velocity of propagation of seismic waves and how a seismograph enumerates the distance from the epicenter of an earthquake.

Answer:
mutualistic
Explanation:
The interaction between two organisms in which both the organism gets benefitted from each other is called a mutualistic relationship. This mutualistic relationship is seen in the concept of endosymbiosis.
According to the endosymbiotic theory chloroplast and mitochondria are evolved by engulfment of different bacteria by ancestral cells. Then these bacterial remained in a mutualistic relationship with each other and the ancestral cell evolved into a eukaryotic cell.
So as mitochondria and chloroplast live with a symbiotic relationship with eukaryotic cells, therefore, it is considered as mutualistic relationship.
Answer:Recall that the glycolytic pathway generates NADH in the cytosol in the oxidation of glyceraldehyde 3-phosphate, and NAD+ must be regenerated for glycolysis to continue. How is cytosolic NADH reoxidized under aerobic conditions? NADH cannot simply pass into mitochondria for oxidation by the respiratory chain, because the inner mitochondrial membrane is impermeable to NADH and NAD+. The solution is that electrons from NADH, rather than NADH itself, are carried across the mitochondrial membrane. One of several means of introducing electrons from NADH into the electron transport chain is the glycerol 3-phosphate shuttle (Figure 18.37). The first step in this shuttle is the transfer of a pair of electrons from NADH to dihydroxyacetone phosphate, a glycolytic intermediate, to form glycerol 3-phosphate.This reaction is catalyzed by a glycerol 3-phosphate dehydrogenase in the cytosol. Glycerol 3-phosphate is reoxidized to dihydroxyacetone phosphate on the outer surface of the inner mitochondrial membrane by a membrane-bound isozyme of glycerol 3-phosphate dehydrogenase. An electron pair from glycerol 3-phosphate is transferred to a FAD prosthetic group in this enzyme to form FADH2. This reaction also regenerates dihydroxyacetone phosphate.
