convergent evolution - called analogy
a potential source of confusion in constructing a phylogeny is similarity between organisms that is due to convergent evolution - called analogy - rather than to shared ancestry. thus for mammals, the backbone is a shared ancestral character, a character that originated in an ancestor of the taxon
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.
