Answer:
Thymidine dimers is likely to be repair as soon as it is originated but if left unrepaired then it causes  frame shift mutations.
Explanation:
In case of Bacterium if UV irradiation induces covalent linkage of two thymidine present adjacently to each other or on a single strand to make thymidine dimers. 
These either excised via DNA repair enzyme like Endonuclease V and the proof reading activity of DNA polymerase I enzyme help in incorporation of nucleotide by taking the unmutated original strand as a template. 
These dimers if not excised before second round of replication than the sequence of newly synthesized strand will be altered. As DNA polymerase III enzyme read thymidine dimers as single thymidine nucleotide and incorporate only 1 adenine in the newly synthesizing complementary strand which results in frame shift mutations 
It is the mutation in which reading frame of codons is shifted or altered due to deletion or addition of a single nucleotide.

light and oxygen are a crucial thing for plants 
 
        
                    
             
        
        
        
The easiest example here is a computer/laptop... e.g. when the CD-ROM is spinning when you are perhaps playing a movie, the kinetic energy causes friction, which results in heat.  All computers need a fan to prevent them over-heating for this very reason.  Therefore heat is lost and energy is wasted.
Another example is a lightbulb.  When a light is switched on and left for a long time, the current flowing through the filament (the thin bit of wire in the bulb) causes heating (due to electron-ion collisions but you may not need to know that) so energy is wasted as thermal energy instead of light energy.
These are just a few examples but other ones you could use are tv screens, kettles, toasters, etc :)
