Answer: "Decreasing the salt concentration of the solution lowers DNA's melting point (Tm)" is not a true statement
Explanation:
Increasing salt concentration would lower the DNA's melting point (Tm), not otherwise.
For instance:
- In 8M urea (8M means 8 Moles per dm3), Tm is decreased by nearly 20°C.
- 95% formamide at room temperature would completely denature the double stranded DNA.
Thus, higher concentration of salts like urea or formamide lowers Tm, not otherwise
Answer:
Natural selection, mutation, and genetic drift are random events.
Explanation:
A mechanism of evolution in which the frequencies of alleles of a population change with generations because of sampling error is known as genetic drift. It takes place in all the populations of non-infinite size, however, its influences are strongest in small populations.
Hope this helps :)
I would say either the first, second, or fourth answer; waves have a very strong impact on the movement of sand and other particles under the water. Erosion of particles off an island are similar in this case.
It wouldn't be anything about a tropical storm; it's no where in the question and we don't know how many storms Florida has or how strong they are.
Carbon dioxide
this is the answer
