I would say the last one. Yes, the coral reef in the south is being threaten but, it’s not the only one. Many other reefs are being threatened. Why? To find the problem to this reef you need to find the problems of other reefs and compare the data. Which ever the most problem cause you get rid of that first.
Answer:
Active transport
Explanation:
Diffusion is when particles (like perfume) spread out everywhere from an area where there is a lot of it to where there is a little to none of it. Active transport is the opposite. A cell for example would use it's own energy to absorb nutrients when it already has quite a lot. Naturally diffusion would make the particles or nutrients go out of the cell because there is a lot of it inside the cell not outside, so active transport is used to absorb as much as the cell can from around it, even when it is full.
Aerophones I think.
oh well brainly want me to type more.
Answer:
Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.
