Answer:
The two strands of DNA are replicated in different ways
Explanation:
DNA replication is a process that occurs during the S phase of the cell cycle that consists of making two identical copies of the double-stranded DNA molecule, which subsequently are distributed in the daughter cells during cell division. During this process, DNA polymerase can add nucleotides in 5' to 3' direction, but not in 3' to 5' direction. In consequence, the DNA strand that has 3’ to 5’ directionality can be synthesized directly, while the DNA template strand that has 5’ to 3’ directionality can't be synthesized in a continuous manner and thereby it is created by adding small DNA fragments, which are known as Okazaki fragments (150-200 nucleotides in size).

Answer:
The average speed of the fish is:
Explanation:
You must take into account that the fish swims 10 laps, so you must multiply the perimeter by 10 to obtain the total meters swam:
- 720 m * 10 = 7200 meters.
Now, you just must divide the total meters swam by the number of minutes that the fish took to do this, so:
- 7200 m / 120 min = <u>60 m/min
</u>
Remember, ever you do an exercise like this, you must check the units, I mean, the units that the exercise wants to be the same you use, in this case, the average speed of the fish is 60 m/min.
