Question 6 1 pts
A lifeguard sees a beach ball floating on the crest of an incoming wave. The ball
briefly disappears, then reappears in the same spot just as the next wave starts
rising. What is probably the main reason that this is happening?
the relatively long period of the wave
the orbit of the water in the passing waves
O a wave amplitude that is taller than the ball
O the low velocity of the wave carrying the ball

thats not a question

on island x the species needed to adapt because they were being subject to predators which didn't inhabit island y.  

the species living around the vents are especially good at dispersal.  

deep-sea vent originates on the floor of the ocean when seawater circulates through hot volcanic rocks, usually situated where the new oceanic crust is being produced.  

biological dispersal refers to the movement of species from their location of birth to their site of breeding, or from breeding site to another. similarly, the oceanic dispersal refers to the movement of the species from one land mass to another by sea crossing.
