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:
300%
Explanation:
The mass of the bacterial culture is triples everyday, meaning that after one day the culture will have 300% of the mass as the culture one day prior.
Answer:
Magnitude and Intensity measure different characteristics of earthquakes. ... Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location. Intensity is determined from effects on people, human structures, and the natural environment.
Explanation:
The correct answer is D. The nucleus transcribes and releases messenger RNA signalling for the enzymes to be synthesized.
<span>
The nucleus is the site of transcription, production of messenger RNA (mRNA). Because of that, it contains a lot of proteins that either directly are involved in transcription or are involved in regulation. mRNA is exported from the nucleus, after being post-transcriptional modified.</span>
Answer:
B. mutualism
Explanation:
Legume plants have the ability to fix atmospheric nitrogen, due to a mutualistic symbiotic relationship with bacteria found in root nodules of these plants.
