Animals in phylum Arthropoda generally have these characteristics in common.
umka21 [38]

Answer:

Chitinous exoskeleton and segmented bodies​.

Explanation:

Phylum Arthropoda are known as jointed legs species which include crabs, spiders, ants, etc. The important characteristic of Arthropoda is they have a hard chitinous exoskeleton that provides them protection and gives flexibility. These phylum species can survive in both terrestrial and marine habitats. Some characteristics of phylum Arthropoda are given below:

1) They have Chitinous exoskeleton which is hardened.

2) Their digestive tract is present at opposite ends of the body and complete with the mouth and anus.

3) They contain jointed limbs.

4) The body structure of these species is showing bilateral symmetry.

Transpiration is the evaporation process used by plants for cooling and to regulate the amount of water within its body. Factors
Stella [2.4K]

Answer:

Transpiration is the process of water movement in the plant in which water is released from the leaves to the environment in the form of vapours.

The transpiration is important to the plant as:

1. Cooling Effect: Transpiration help lower down the temperature of the plant by evaporating water.

2. The ascent of Sap: leads to the uptake of water in the plant.

3.  Removal of Excess Water: removes extra water from the plant.

4. Maintain turgidity: helps maintain turgidity which leads to maintains shape and structure.

5. Photosynthesis: supplies water for the photosynthesis.

The process also has disadvantages to the plants as:

1.  Wilting: the excess loss of water causes wilting of leaves during noon.

2. Reduced Yield: the wilting reduces the formation of fruits, flowers and seeds.

3. Wastage of Energy: Loss of water leads to the waste of energy which is used in the conduction of water and absorption.

The climate change has changed the ability of the plants to undergo transpiration and plants has adapted to maintain equilibrium by producing hair, thorns, thick cuticle, sunken stomata, cladodes and phylloclades.

How the seismic tracings recorded at station A and station B indicate that station A is farther from the earthquake epicenter th
VMariaS [17]

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 function of mRNA, tRNA, and rRNA.
Vedmedyk [2.9K]
Function of mRNA
                               The mRNA is formed inside the nucleus in a process called transcription. This mRNA contain codon responsible for the formation of specific type of protein. In translation this mRNA is converted into protein.

Function of tRNA

                             tRNA is found in cytoplasm and possess amino acids. During translation they attach to the base pair of mRNA with the help of anti-codons. 

Formation rRNA:
                           rRNA is the principle component of ribosome. Ribosome is that organelle which help in attachment of mRNA and contribute in translation.
