Taq polymerase enzyme important for efficiency in PCR because it is thermostable polymerases that remain active at high temperatures (90 -95 degree Celsius) a beyond the denaturation temperature of DNA.
PCR :
Polymerase chain reaction (PCR) is a laboratory technique for rapidly amplifying millions to billions of copies of a specific segment of DNA, which can then be used for further research.
Taq polymerase is a DNA polymerase derived from bacteria called Thermus aquaticus, which are naturally thermophilic and is a thermostable polymerases that remain active at temperatures higher than the temperature at which DNA is denatured. This allows PCR to be used on DNA samples without the need to add new DNA polymerases after each cycle.

#SPJ4
A procaryotic cell has five essential structural components: a nucleoid (DNA), ribosomes, cell membrane, cell wall, and some sort of surface layer, which may or may not be an inherent part of the wall.
Answer:
The answers to the blanks in the question in order is as follows:
- sweat
- lungs
- feaces
- Rectum
Explanation:
This question is describing the excretory organs and their excretory products. Excretion is the process by which waste products of metabolism are removed from the body system.
- As mentioned in the question, the SKIN is an excretory organ that excretes SWEAT which is made up of water, salts, and chemicals like urea.
- Lungs is another organ that excretes carbon dioxide (CO2) and water (H2O) as products of cellular respiration.
- The large intestine also produces FEACES, which is stored in the last part of the large intestine called RECTUM before it is excreted through the anus.
Answer:
A bicameral legislature has legislators in two separate assemblies, chambers, or houses. ... Enactment of primary legislation often requires a concurrent majority—the approval of a majority of members in each of the chambers of the legislature.
