In pcr, it is important to use taq dna polymerase, as opposed to other dna polymerases. this is because taq is capable of synthesizing dna AFTER EXPOSURE TO 94° C.
Taq polymerase is a thermostable DNA polymerase. This means that it can withstand high temperature and is ideal in synthesizing DNA during PCR.
Taq polymerase under certain temperatures
1) optimum temperature for activity<span> is 75–80 °C,
2) with a </span>half-life<span> of greater than 2 hours at 92.5 °C,
3) 40 minutes at 95 °C and 9 minutes at 97.5 °C,
4) can replicate a 1000 </span>base pair<span> strand of DNA in less than 10 seconds at 72 °C</span>
Answer:
Option B, maculae/static equilibrium
Explanation:
The specialized sensory receptors of the macula are located in the utricle and saccule and are responsible for detecting the static equilibrium through their hair cells. The hair cells have large number of stereocilia and one single kinocilium which detects the movement of otolithic membrane caused by the release of calcium carbonate. The otolithic membrane moves up and down and to and fro.
Hence, option B is correct
humans cannot impact one of Earth's systems without impacting the others because Earth's systems are interconnected. They interact with each other, moving matter from one system to the other. Changes to the atmosphere brought about by human activity eventually lead to changes in the biosphere and hydrosphere.
