Answer:
3. liquid waste me directly into the ground water
Explanation:
Aquifer is a layer of water which is present inside the soil at a certain depth. There are certain areas where water is added to the aquifer and maintain the water level. These aquifers were polluted if liquid waste is dumped in these aquifer recharge areas and when this water is extracted through wells so health of both plants and animals are adversely affected. So for that reason liquid waste should not be dumped in recharge areas of aquifer.
If the herring was eaten by something that either ate or was being eaten by the gulls, then they would be affected differently. If the gulls had less food because there food source had less food if the herring disappeared, then they would have a lower or population of perhaps become extinct. If the thing eating the herring became extinct because it had less food, then the gulls population would increase and either boom and bust or grow and level out once they reached the carrying capacity.
Answer:
Water erosion refers to the removal of the top most or surface layer of soil by the flow of water. The long term effect of water erosion can be because of drastic rain fall and may be because of flood. These two reasons can adversely effect the human life. The water erosion is responsible for the removal of fertile layer of soil, therefore, the region will not be appropriate to grow vegetation. The long term effect may result in stagnation of water, therefore, long time is required so that the region gets dried. The long term accumulation of water over an agricultural field can spoil the crop production.
Prevention that can be taken to reduce long term effect of water erosion:
1. Plantation of long root bearing trees over flood prone regions and around the agricultural field: This will allow the trees to tightly hold up soil and prevent it's erosion.
2. Add rocks over the soil: In an agricultural field or flood prone area, the rocks will act as barrier for the movement of run off water, hence, will prevent water erosion. It will increase the absorption of water by soil.
3. Building of walls: This will also act as a barrier in a flood prone region and will prevent the water being added up to the agricultural land.
4.Remove soil compaction: If the soil compaction of the effected region is removed, the water retention property of the soil can be improved. Machines, animals and humans can be used for this purpose to remove the compaction of upper layer of soil.

Insulin and glucagon are hormones that help regulate the levels of blood glucose, or sugar, in your body. Glucose, which comes from the food you eat, moves through your bloodstream to help fuel your body.
Insulin and glucagon work together to balance your blood sugar levels, keeping them in the narrow range that your body requires. These hormones are like the yin and yang of blood glucose maintenance. Read on to learn more about how they function and what can happen when they don’t work well.
