Half life is the time taken by a radioactive isotope to decay by half of its original mass. In this case the half life of carbon-14 is 5500 years. 
The original mass is 30 g and the new mass is 3.75 g. 
New mass = Original mass × (1/2)^n, where n is the number of half lives; 
3.75 = 30 × (1/2)^n
 1/8 = (1/2)^n
 n = 3 
Thus, the time taken will be; 3 × 5500 = 16500 years.

Answer:

When ATP is broken down to ADP

Explanation:

Energy is released from a molecule of ATP when the substance is broken down to ADP

What is point source water pollution?

Point-source water pollution is the one type of water pollution which is easy to recognize because it generates from a single source or event and affects a specific area.

The negative effects of single point origin is deteriorating water quality which damage the environment, health conditions.

Destruction of biodiversity is another negative effect of water pollution depletes aquatic ecosystems and prompt unbridled proliferation of phytoplankton in lakes called as eutrophication.

The solution to reduce water pollution is reduce carbon dioxide emissions to prevent global warming and acidification of the oceans. Another is to reduce the use of chemical pesticides and nutrients on crops.
