Compositional layers are determined by their components, while mechanical layers are determined by their physical properties.
Answer:Long term drought, change of season from winter to summer, forest fire are unfavorable environmental factors which can deplete the amount of resources already available with the ecosystem. The long term drought will be a condition in which the ecosystem will suffer from non-availability of water.
Explanation:
The offspring would be 50% BB and 50% Bb, so the plants would be tall. :)
Answer:
Along the Kuroshio Current, because it is carrying water north towards melting ice caps
Explanation:
The ocean currents have the tendency to be faster when they are warmer, and to be slower when they are colder. The reason for this is that the warmer water is less dense, thus it can move more quickly, while the colder water is denser, thus heavier, so it moves slower. The Kuroshio Current moves from the lower latitudes toward the higher latitudes. As it does, this ocean current is becoming colder and colder as it gets closer to the higher latitudes, so it is becoming denser, heavier, and because of it slower. Another thing that will contribute to this current's slowing down are the melting ice caps because of the climate change, as they will make the water even colder, and the Kuroshio Current will come across this cold water, so it will decrease its speed significantly.
