<h3><u>Answer;</u></h3>
aquifers
<h3><u>Explanation;</u></h3>
- <u>Most liquid freshwater is found under the Earth's surface as groundwater or aquifers, while the rest is found in lakes, rivers, and streams, and water vapor in the sky. </u>
- About 68% of freshwater is found in glaciers and icecaps such as in Greenland, the poles, and other glaciers. Another 30% is found in groundwater, which basically means aquifers. Only 1% of freshwater is found in surface water such as lakes, rivers, etc.
Answer:
Introduction on Argentinian Red And, <em>Solenopsis invicta</em>, in the United States.
Explanation:
A species is considered to be introduced when it has been released intentionally or accidentally in a new place or area, out of its natural geographical distribution range, during historical times.
The, Argentinian Red Ant, Solenopsis invicta was introduced by accident in the United States in the 1930 year when some commercial ship coming from Brazil unloaded infested merchandise. Since that date, it has been colonizing several areas, expanding in a range of 30 to 50 kilometers per year. Nowadays it is occupying more than 110 million hectares, causing several problems:
- Biological problems: It is a very aggressive species that can <em>affect animals and plants</em>. In Texas, the <em>invertebrates' biodiversity decreased by 40% and the local ants decreased by 70%.</em> Their nests' building affects the roots of plants causing important <em>harvest losses</em>.
- Economical problems: The United States government has expended more than 250 million dollars trying to solve the problem, while the yearly losses exceed 1,000 dollars. The harvest losses have causes an important decrease in production.
- Sanitary problems: These ants might be considered dangerous as they have attacked people and animals. Texas invests 750,000 dollars a year to treat wounds in cattle and other affected animals.
There are some steps to prevent and reduce biological invasions, such as introduction prevention, eradication <em>when it is still possible</em>, contention to <em>avoid the species expansion</em>, expansion control (biological, mechanical, chemical), and restoration of the affected areas.
In the case of the Red Ant it would have been very important to control the state of the merchandise coming from Brazil to avoid the ant's introduction and its posterior spread. It also would have been important to deal harder with the problem when it was recently to avoid the ants' expansion by educating the people about invasive species and how to react about it, and by applying some eradication actions when it was possible. Nowadays the species is under control, but they can not completely eradicate it.
During the sanger dideoxy sequencing method of determining the sequence of DNA, the purpose of the dideoxy nucleotide is to amplify a target segment of DNA.
<h3>What is DNA?</h3>
This is referred to as deoxyribonucleic acid and is the genetic material of living organisms. They are composed of chains of nucleotides which ensures that traits are passed from the parent to offspring.
The purpose of the dideoxy nucleotide in DNA sequencing is to amplify a target segment of DNA so that the DNA sequence can be determined precisely.
