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>
Hello there,
#5- Proteins
#6- is incorrect the answer is-->> ATP synthesis
#8- Photosynthesis
#9- Cell recognition components
Hope this help,
Have a nice day!
The answer C, the carbon cycle
Flatworms (Platyhelminthes) are phylum of unsegmented, soft, flat invertebrates.
Flatworms have no body cavity which is why they are flat. The advantage of a flat body is facilitated respiration and circulation. Flatworms do not have respiration and circulation system. But, oxygen diffuses across the skin and reach all parts of the body thanks to a flattened shape. Also, it is easy to hide from predators because they can get almost everywhere thanks to the body shape.
The actual answer is, "A", an ocean trench.
You can find out more about them by researching them up on Google, it's only a few phrases and a hit on the enter key :P
