Lakes become acidic due to acid rain. When CO2 rises into the atmosphere and falls back down as a form of rain, it will runoff into lakes, ponds and other water sources.
Oxygen can enter aquatic systems through diffusion from the atmosphere at the water's surface. Aquatic plants and algae also produce oxygen through photosynthesis, contributing to the oxygen levels in the water. Additionally, oxygen can also be introduced into aquatic systems through mixing with air during wave action or through aeration systems.
No, different systems use different servers. But that would be cool
Aquatic animals, such as fish, have oily skin to help reduce friction as they move through water. The oil on their skin also helps to protect them from waterborne pathogens and maintains their body temperature by acting as insulation.
Of course they are. Everything in the environment is affected, actually. But focusing in on the aquatic systems I could give you more information. First of all they are GREATLY affected! The acid rain raises the pH levels of the water. As this happens it kills off many species of aquatic life. The first to go are normally the craw fish and clam species, then most fish die off. Depending on how quickly the acid rain gets to the aquatic system, some species may be capable of actually adapting to the rain acidic water. When it comes to humans, the aquatic systems that are affected WILL affect us! We have to drink that water sooner or later! I understand it's put through filters and cleaned but the acidic water will still affect us.

Some different operating systems such as different versions of Linux may be downloaded for free through Ubuntu, Cnet or Linux. Other systems such as those for Microsoft or Apple must be purchased and then downloaded via the vendors own portal.

nope sorry
