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.

Explain the role convection plays in the rock cycle
Romashka-Z-Leto [24]

Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. All rocks are made up of minerals. A mineral is defined as a naturally occurring, crystalline solid of definite chemical composition and a characteristic crystal structure. A rock is any naturally formed, nonliving, firm, and coherent aggregate mass of solid matter that constitutes part of a planet.

Kryger [21]
The correct answer is A, parathyroid gland.

The parathyroid hormone is secreted by the parathyroid gland which <span>inhibits osteoblasts, stimulates osteoclasts,</span> reduces the calcium output by the kidneys and promotes absorption of the calcium by the small intestines. Calcitonin, secreted by the thyroid gland, also works to a similar effect.

Eddi Din [679]
Think where mitochondria are found in the greatest numbers - they are found (for example) in liver cells, kidney cells, muscle cells etc. These tissues carry out a lot of work and thus require lots of energy. 

<span>Fat is a storage product that sits there until required but the thyroid does lots of work involved in metabolism and therefore requires plenty of energy.

<h2>Hypomorphic allele</h2>

Explanation:

  • Hypomorphic Alleles : A change that reduces, however, doesn't dispense with a gene's usefulness is hypomorphic. A progressively extreme condition, amorphic transformation, dispenses with the gene's capacity.
  • The great analyses characterizing hypomorphic alleles go back to the 1930s. Herman Miller, who won a Nobel Prize for finding that radioactivity causes changes, considered the eyeshade of organic product flies. These flies typically have red eyes, yet freak assortments can have white or apricot-hued eyes. The allele liable for various natural product fly-eye hues is known as the white allele, with the contraction "w."
