A couple of things will happen. One, the paddlefish may be hunted into nonexistent numbers, meaning that that amount of zooplankton would increase. Two, due to the decreased amount of the paddlefish, the lampreys would moves elsewhere or begin to feed on something else.
Answer: Groundwater and surface water are connected. When groundwater is overused, the lakes, streams, and rivers connected to groundwater can also have their supply diminished. Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops.

Answer:
2.33 mL
Explanation:
Given data
- Initial pressure (P₁): 1 atm (Standard pressure)
- Initial volume (V₁): 80.0 mL
- Initial temperature (T₁): 273.15 K (Standard temperature)
- Final pressure (P₂): 92.0 atm
- Final temperature (T₂): 460°C + 273.15 = 733 K
We can find the new volume using the combined gas law.
Answer:
A
Explanation:
Chlorofluorocarbons generally abbreviated as CFCs are a group of organic chemicals used in several household and industrial materials and are responsible for global warming and ozone depletion.
Global warming is the general increase in the atmospheric temperature of the earth continually over the years. It is a direct consequence of climate change which is caused by the continuous release of green house gases into the atmosphere which trap radiated heat from the sun.
Ozone depletion involves anthropogenic activities which lead to decreasing the natural spread of the ozone layer which prevents the direct contact between the sun UV radiation and the earth.
CFCs are implicated in both cases as they are responsible for the two I.e they cause global warming and also deplete the ozone layer. Years back they are basically used in most aerosol cans like perfumes spray, insecticide spray etc. However as a result of the increased knowledge of their dangers, there had been legislations which had cut down on their continuous usage with alternatives being used
Answer:
There are three ways that scientists have proved that these sub-atomic particles exist. They are direct observation, indirect observation or inferred presence and predictions from theory or conjecture. Scientists in the 1800's were able to infer a lot about the sub-atomic world from chemistry.
