Answer:
Sulfur; nitrogen. 
Explanation:
Acid precipitation results when sulfur and nitrogen compounds react with water in the atmosphere.
This acid precipitation is also known as acid rain and it is typically caused by the chemical reaction between sulfur oxide and nitrogen oxide which are released into the air as a result of burning fossil fuels, with water and other chemical elements present in the atmosphere.
Generally, acid precipitation (acid rain) usually have a pH of about 5.1 or below and as such, it is very acidic nature i.e possessing a large amount of hydrogen ions. 
Hence, acid precipitation (acid rain) when washed to the earth has negative or harmful effects on various living and non-living organisms such as animals, plants, cars, buildings etc.

Answer:
According to a mind-bending new theory, a black hole is actually a tunnel between universes—a type of wormhole. The matter the black hole attracts doesn't collapse into a single point, as has been predicted, but rather gushes out a "white hole" at the other end of the black one, the theory goes.
 
        
             
        
        
        
When a substance abuse treatment program is acquired by another program, the next course of action is that <u>if any patients refuse consent to transfer, those records maybe destroyed or retained in compliance with the statue of limitations</u>
Explanation:
The Substance Abuse Confidentiality Regulations devised by the Substance Abuse and Mental Health Services Administration provides confidentiality to the patients undergoing a treatment program for substance abuse.  
Under this regulation, section 2.19 details and sets forth rules to follow when a program is acquired by another program. 
This states that the program must either purge the identifying details of the patient from its records or destroy it until or unless the patient consents for the transfer of details or information in the records.
This condition can be exceptional in compliance with the statute of limitations and the records can be retained, like in case of any legal requirements

The reason why there are more hares than foxes in the ecosystem is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to supports the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development.
