<h2>Answer:</h2>

The wavelength of <u>light</u>.

<h2>Explanation:</h2>

The electromagnetic spectrum shows the parts of light orchestrated by their wavelengths. The range for the most part comprises of both visible as well as invisible light. Together, they are called electromagnetic radiation. They are electromagnetic in light of the fact that they comprise of both an electric field and an magnetic field, and these fields travel in wave and travel at the speed of light: 3.00 × \bold{10^8} m/s.  

When the light gets scattered it gives out color in the form of VIBGYOR which is elaborately called as Violet, Indigo, Blue, Green, Yellow, Orange and red. These colors are arranged in the spectrum based upon the wavelength.

Which branch of the autonomic nervous system (ans) mobilizes the body during extreme situations, such as rage or fear?
Shalnov [3]
There are two branches of the autonomic nervous system, namely the sympathetic nervous system and the parasympathetic nervous systems. Both of which regulates bodily functions involuntarily but in different manners. The parasympathetic system is the system primarily activated in "relaxed" states or "rest and digest" states. These include digestion, urination, slowing of heart rate, slowing of respiratory rate, etc. The sympathetic nervous system on the other hand is primarily activated by "flight or flight" response such as rage or fear. These include inhibition of digestion, increase in heart rate and respiratory rate, sweating, etc.

A) In how many cases in the genetic code would you fail to know the amino acid specified by a codon if you knew only the first t
Vesna [10]

Answer:

a) 28 cases

b)  3 cases

Explanation:

a) From the table of genetic codes, there are 28 codons that specify more than one amino acid assuming only the first two nucleotides are considered. In these cases, one cannot outrightly specify the amino acid the genetic codes are coding for without knowing the last nucleotide of the codes. <em>For example, UU can be for Phenylalanine or Leucine, CA can be for Histidine or Glutamine, etc. </em>

b) From the table of genetic codes, the first two nucleotides of Arginine can be either of CG or AG, that of Serine can be either of UC or AG while that Leucine can be either of CU or UU. Only in these <u>3 cases</u> would one fail to know which are the first two nucleotides assuming the name of the amino acids are given.

<em>See the attached image for the genetic code.</em>

Subduction zones are found under which kind of plate
kvv77 [185]
High rates of volcanism, earthquakes, and mountain building are the sites of subduction zones. They occur in convergent boundaries found in tectonic plates of both oceanic and continental crusts. Subduction zones occur when one tectonic plate moves under another tectonic plate, sinking into the mantle as the plates converge again.
<span>
Regions that are within subduction zones experience an average rate of convergence of 2-8 centimeters per year. They are subject to many earthquakes because of the collisions that occur within the tectonic plates. </span>

Which seismic waves are felt first at a seismic station
vlabodo [156]
Question-
Which seismic waves are felt first at a seismic station

Answer-
Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. They are the energy that travels through the earth and is recorded on seismographs.


There are several different kinds of seismic waves, and they all move in different ways. The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves.

BODY WAVES
Traveling through the interior of the earth, body waves arrive before the surface waves emitted by an earthquake. These waves are of a higher frequency than surface waves.

P WAVES
The first kind of body wave is the P wave or primary wave. This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth. It pushes and pulls the rock it moves through just like sound waves push and pull the air. Have you ever heard a big clap of thunder and heard the windows rattle at the same time? The windows rattle because the sound waves were pushing and pulling on the window glass much like P waves push and pull on rock. Sometimes animals can hear the P waves of an earthquake. Dogs, for instance, commonly begin barking hysterically just before an earthquake 'hits' (or more specifically, before the surface waves arrive). Usually people can only feel the bump and rattle of these waves.

P waves are also known as compressional waves, because of the pushing and pulling they do. Subjected to a P wave, particles move in the same direction that the the wave is moving in, which is the direction that the energy is traveling in, and is sometimes called the 'direction of wave propagation'.
