Explanation:
False, they are inexhaustible. If we were to use the resource as much as possible, it would exhaust and not be able to be used again.
Answer:
DNA replication follows semi conservative mode of replication
Explanation:
The results of Meselson and Stahl's experiments can be explained by semi conservative mode of DNA replication. According to it, the two DNA strands separate and both are used for synthesis of new DNA strands such that the new DNA molecule has one parental and one new strand.
In the experiment, originally the medium was 15N so all the DNA molecules had 15N. Later the medium was changed to 14N. In first round of replication in new medium, the two 15N strands in a DNA molecule separated and formed new strands using 14N. So all the DNA molecules had one 15N and one 14N strand.
In the second round of replication, the 15N-14N hybrid DNA molecule separated again. Now, 15N gave rise to 14N strand and 14N strand also gave rise to 14N strand such that half of the DNA molecules were 15N-14N hybrids and half were 14N-14N. Hence, researchers concluded that DNA replicated according to semi conservative mode of replication.
Answer:
Explanation: I'm pretty sure that wind power is a renewable resource. An advantage would be that we can use it to power many different things, and for the foreseeable future, it won't run out. A disadvantage would be that it some countries, they don't have access to wind power, because the country may not have the money to pay for anything to be installed in order to use it, or there may not be anywhere to put anything to generate wind power.
I'm not so sure about coal and hydroelectric power, though. Hope his helped you some!
