Answer:
The correct answer is - B. The seeds are in berries that are eaten by birds and dropped as waste away from the plant.
Explanation:
The mountain ash trees contain red berries fruits that attract birds and other organisms. These birds eat these berries and eat berries and fly over the hills or mountains and after digesting they drop the seeds of these berries with the digestive waste. These berries grow on the mountains far from the original source as birds carry them by flying away after eating.
Thus, the correct answer is option B.
The answer is (C) Replication
Though occasional errors could occur in cells during replication; the cells have error checking and proofing mechanisms that reduce the rate of error to one to several million replications in higher eukaryotes.
After all, one mismatch error during replication would not result in major effects. The others choices, however, have higher rates of causing genetic abnormalities.
