Answer:
D. Natural selection
Explanation:
Natural selection supports this theory.
From the given choices, the first that would be deposited by the river is the sand. This is because sand are comparatively smaller than all of the given substances. This makes it easier for river to transport it and deposit it.
Answer:
The correct answer is option (B) "In pursuing a swerving insect, a beetle alters its course while running and its pauses become more frequent as the chase progresses".
Explanation:
One hypothesis suggest that the tiger beetles stop for a moment when they attack because it can't keep its pace and they have to rest, while the other hypothesis suggest that the tiger beetles could not process the rapidly changing visual information when running. The experiments results would support only the second hypothesis if they show that in pursuing a swerving insect, a beetle alters its course while running and its pauses become more frequent as the chase progresses. If a beetle altering its course have to stop more often than a beetle running straight, it would make sense that it has to stop because is unable to process the changing visual information rapidly enough.
