Answer:
Organic molecules have more chemical potential energy than inorganic molecules
Explanation:
Chemical molecules can either be organic or inorganic depending on whether they contain certain elements. Organic molecules are molecules that contain in their structure a carbon-hydrogen bond (C-H) e.g C2H4, C6H12O6 etc. while inorganic compounds do not contain the carbon and hydrogen elements bonded together e.g CO2, H2S
Considering the substances/compounds involved in photosynthesis and respiration, glucose (C6H12O6) is the only organic compound while every other compound is inorganic. However, organic compounds store more potential energy called chemical energy in its C-C or C-H bonds than inorganic molecules do.
It allows cells and antigen presenting
cells to present a large range of antigens (in the range if millions) to T cells so there is an appropriate
immune response against the invading pathogen
or cancer. This is possible without changing or having many types of MHC
complexes.

Answer:
Explanation:
There is a wide range of water pollutants usually influenced by humans. Water pollution is a huge problem that affects water ecosystems and their surrounding. Pollutants can be divided into two major groups, according to their source: point source pollutants (from a single source) and non-point source pollutants (from more different sources).
- Agricultural and industrial pollutants-consequence of the use of fertilizers and pesticides; the pathogens are washed into the water together with nutrients (such as phosphorus and nitrogen) which lead to the algae blossom.
The only way to limit and control this type of pollution is by government regulations.
- Oil pollution-consequence of tanker spills
This type of pollution can sometimes be removed (digging up the tanker).
- radiactive, toxic substances, plastic bags are also the huge problem, especially in the ocean
