Answer:
The correct answer is option A. "They only introduce supercoiling and cannot relax a covalently closed circular DNA".
Explanation:
Type II topoisomerases are enzymes that regulate the winding an unwinding of DNA during DNA replication. Basically, these enzymes are the scissor that remove the knots and tangles formed during the replication process. Is false to affirm that type II topoisomerases only introduce supercoiling and cannot relax a covalently closed circular DNA. Bacterial type II DNA topoisomerases work with the circular DNA of bacterium by changing the linking number of circular DNA by ±2.

If there was a picture it would help but im going off information i know aboutweathering and ersion.
Yes, physical wearthing did create this arch because waves they carry sedoment pieaces away or off of that rock and it possible could have been frozen off.

I really tried my best to help you and i hope this is the answer your teacher is looking for! Good luck and please make sure to word it in your own words :)
Answer:
As competition increases and resources become increasingly scarce, populations reach the carrying capacity (K) of their environment, causing their growth rate to slow nearly to zero. This produces an S-shaped curve of population growth known as the logistic curve (right).
