A tympanic membrane, (is also called a tympanum), is the circular patch of skin directly behind the frog’s eye that we commonly call an eardrum. It functions much like our’s does.
The tympanum sends sound waves to the middle of the war then to inner ear, which allows a frog to hear both in the air and below water.
To copy the DNA, recombinant DNA method use bacteria such as E. Coli whose plasmids has been combined with various gene to produce the substance that is wanted.
Answer:
It depends on the size of the amplified DNA fragments (for example for SPAR markers consisting of 200 bp in length >> 1600 / 200 = 8)
Explanation:
The PCR based single primer amplification reaction (SPAR) methods are tools for detecting genetic diversity by using DNA markers such as Simple Sequence Repeats (ISSRs), Minisatellite DNA regions (DAMDs) and Random Amplified Polymorphic DNAs (RAPDs), which can be used alone or combined with each other. In the last years, the SPAR methods have gained attention in the scientific community because they are cost-effective and highly effective for the detection of both intraspecific and interspecific genetic variation. In the SPAR methods, the size of the bands will depend on the length of the amplified DNA fragments.
Prescribed burns are referred to as ridding of the forest by burning the dead leaves, tree limbs, and preventing the destructive wildfire.
The prescribed burns can help in maintaining healthy ecosystems.
The prescribed burns can be explained as:
- The prescribed fire can reduce hazardous fuels, protect the human communities from wildfire.
- The prescribed burns minimize the spread of pest insects and any dangerous diseases.
- Prescribed burns improve the habitat for the endangered species, and remove the unwanted species that threaten the native species to ecosystems.
Thus, prescribed burns are useful to maintain a healthy ecosystem.
