Answer:
Yes.
Probability of such child = 1/2 or 50%
Explanation:
According to the question, below are the genotypes and phenotypes possibilities:
aa = normal vision & no headache
Aa = normal vision & no headache
AA = blindness & headache
Male Female
Aa aa
Possible genotypes of progeny: Aa Aa aa aa
So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.
Mathematical expression is as under:
2/4 = 1/2 that means 50% progeny.

Plant A listens to classical music for three hours each day
Explanation:
- Music affect plant growth of plants through the vibrations that it creates to the sound waves.Classical music causes more pressure to the sound waves causing vigorous vibrations which is picked up by the plants speeding up the protoplasmic movement in the cells.
- The vibrations causes movement of the plant cells which speed up growth of the plants by stimulating the plants to produce more nutrients enabling them to germinate having more leaves,greater in size and other improved characteristics which means the plant's genetic chromosomes were changed.
- Also in the soil is able to produce good fungi and bacteria encouraging better root development due to healthy vines resulting to vigorous growth and better fruit.
- Moreover the plants are able to receive special attention and care from the farmer thus enhancing faster growth.
