Hi! I believe that the lasers are used for measuring the earthquakes movement and how much worse it is going to be with the next earthquake. But they would also measure how much force there was and how much more or less there will be. :) Hope this helps. :)
Answer:
Yes, extra chromosomes can be received by the tasmanian devil.
Explanation:
Extra chromosomes can be received by the tasmanian devil due to tumor disease in the tasmanian devil. In the beginning the old genome of tasmanian devil has 13 chromosomes but with the tumor disease, it receives one extra chromosome and completed 14 chromosomes. Tumor occurs when the dead cells are not removed from the body and the new ones are formed.
Answer:
<h2>They provide a 3’ end for the DNA polymerase.</h2>
Explanation:
Polymerase chain reaction (PCR) is an in-vitro method to making copies of a specific DNA sample in a very short time.
Polymerase chain reaction was invented by Kary Mullis in 1983.
Primers are specific to the DNA which we want to replicate and they bind to the specific sequence which is complementary to it. Primers provide a 3’ end for the DNA polymerase.

Explanation;
Refrigerants are divided into two groups according to toxicity:
-Class A signifies refrigerants for which toxicity has not been identified at concentrations less than or equal to 400 ppm; and
-Class B signifies refrigerants for which there is evidence of toxicity at concentrations below 400 ppm.
They are also divided into three groups according to flammability:
-Class 1 indicates refrigerants that do not show flame propagation when tested in air at 21°C and 101 kPa;
-Class 2 indicates refrigerants having a lower flammability limit of more than 0.10 kg/m3 at 21°C and 101 kPa and a heat of combustion of less than 19 kJ/kg;
-Class 3 indicates refrigerants that are highly flammable as defined by a lower flammability limit of less than or equal to 0.10 kg/m3 at 21°C and 101 kPa or a heat of combustion greater than or equal to 19 kJ/kg.
-Therefore; the answer for the above question would be Class B and class 3.
