Answer:
C. UV light  
Explanation:
Some air purifiers use catalyzed ultraviolet light to disinfect the air. In oxidative processes with ultraviolet radiation (UV), high quality UV lamps, yield and radiation react with titanium that catalyzes the "burning" of microorganisms, odors and impurities difficult control by the usual systems.
Ultraviolet light eliminates the formation of mold in the air conditioning system, reduces the incidence of viruses and bacteria, preventing their multiplication and disinfects air that passes through the air conditioning system.
 
        
             
        
        
        
Because that's the starting tempture to rising. for example if your body temperature starts naturally at 80°, as the weather changes your tempture it increases or decreases as it goes.
        
             
        
        
        
Answer:
In some mice, fur color is inherited through incomplete dominance. The colors that are possible are black fur, white fur and grey fur. Grey is the trait that is inherited through incomplete dominance. Scenario: a grey fur male mouse and a grey fur female mouse have 8 babies. The offspring that result are: 2 black fur, 5 grey fur and 1 white fur. But this is not what is statistically expected from that cross. Explain why this is still a probable outcome. This is as a result of mutation
Explanation:
Mutation is the sudden change of a gene, from the above explanation mating of an incomplete grey fur dominance with an incomplete grey fur dominance should not have had offspring with 2 black fur, 5 grey fur and white fur. Normal mating should have produced also an incomplete grey fur dominant offspring 
 
        
             
        
        
        
The most efficient procedure that scientist can use to obtain more
recombinant dna for a particular trait is  Clone the  dna in
a biological vector. This method will give more assurance that they
will get the traits that they  wanted form the subjects.
