Not habitat I missed it. Should be ecological footprint
Transpiration is a water loss from a plant in the form of water vapor through small pores on the leaves. Plants take water from a soil through roots and release it into atmosphere through the leaves. This happens due to water gradient from the roots to the leaves. If for any reason transpiration stops, the water could not be released from the leaves, and consequently, the less water will be absorbed from the soil.
the answer is true, have a good day
B. Use a nucleic acid probe.
C. Subject the specimen to amniocentesis.
D. Use the polymerase chain reaction.
E. Subject the DNA to restriction enzymes.
Answer:
D. Use the polymerase chain reaction
Explanation:
Polymerase chain reaction (PCR) is a molecular technique used to make multiple copies or amplify a particular DNA sample. This enables scientist conduct thorough genetic analysis on minute sample of DNA, simply by amplifying it to a large quantity.
The PCR machine is usually used to amplify DNA fragment. The DNA fragments undergo three major steps successively: denaturation, annealing and elongation
The archaeologists would use the Polymerase Chain Reaction (PCR), a method for amplifying a specific fragment of DNA, to get sufficient DNA from the small scalp tissue sample for gene analysis. So the correct option is D.
To enhance the amount of DNA for a thorough analysis of the ancient human genes, the archaeologists would use the polymerase chain reaction (option D). The polymerase chain reaction, commonly known as PCR, is a method used to make numerous copies of a specified fragment of DNA. PCR is highly beneficial in research scenarios when only a small amount of DNA is available, as this technique can amplify a single or few copies of a specific DNA sequence to generate thousands to millions of copies. Techniques like electrophoresis, use of a nucleic acid probe, amniocentesis, or subjecting the DNA to restriction enzymes, are not primarily for amplification of DNA, but serve other purposes such as DNA separation, detection, prenatal testing, or DNA cutting at specific sequences, respectively.
