Answer:
Heating an atom excites its electrons and they jump to higher energy levels. When the electrons return to lower energy levels, they emit energy in the form of light.

Answer:
150.
Explanation:
150 flies are expected to have normal body color and to be eyeless in F2 generation. The reason for that population is the ratio of the species produced. The ratio of the species are 9:3:3:1. Ratio 9 refers to first parent while 1 refers to second parent and the middle 3's represent the hybrid formed. So the population of first parent is 450 and population of second parent is 50 while the population of two hybrids are 150 each.
 
        
             
        
        
        
The correct answer is option D, difficulty of redesigning workable ecosystems
Reason - 
The area that was redesigned into an ecosystem actually failed to attract the endangered species of clapper rails in California because of the following two reasons –
a)	Failed attempt of restoration of Cord grass ( a tree which is a dominant tree in the nesting habitat of clapper rail) . Even if few such trees were there they could not grow to their full height and thus were incapable of providing adequate nesting cover
b)	Due to the lack of predatory insect, some herbivore insect in the ecosystem attacked the green grasses thereby making the nesting inadequate.
