Precipitation is the primary source of water stored in an aquifer. the correct option in regards to the given question is the first option.
An aquifer is actually an underground layer of water that
contains permeable rocks, gravel, sand etc. the water can be brought to the
surface by making a water well. Hydrogeology is the study of aquifers and the
way of water flow in the aquifers. The depth of the aquifers differs from area
to area and the aquifers that are closest to the surface are used for drinking
and irrigation purposes.
Explanation:
Modern methods indicate that the mutation rate is roughly one to two mutation per 10,000 genes per generation.
Once entering the atmosphere the heated up water vapor (that's the process of evaporation) cools back down (the atmosphere is cooler than the Earth you see). it makes clouds Their it will condense until it's heavy enough to fall to Earth as precipitation!
Answer:
There are no options in this question but generally a sample of DNA can be increased;
By using Polymerase Chain Reaction (PCR) technique.
Explanation:
This question describes the application of making molecular biology to solving a crime problem; a branch called forensics. In this case where an insufficient small amount of DNA sample was recovered from the blood in a crime scene, the polymerase chain reaction technique, commonly known as PCR can be used to increase the DNA sample.
In the 1980's, a molecular technique used to amplify part of a template DNA strand to produce several copies of it, was invented by Kary Mullis and his colleagues. This amplification refers to the numerical increase in the number of DNA sequence.
Answer:
The correct answer would be - 9 hours.
Explanation:
The half life of a drug is the time that is required to decrease or reduced to one half of the its original achieved level or the highest amount previously taken. The half life of drug is also known as the time a drug take to complete its action.
At a dose of 500 mg the Fluoxitine drug would be 250 mg in 3 hour as it is given that half life of this drug is 3 hours, 125 mg in 6 hours, and in the end 62.5 mg in 9 hours.
Thus, the correct answer is : 9 hours.
