Answer:
The correct answer is A) DNA passed from the heat-killed strain to the living strain.
Explanation:
Griffith's in 1928 showed that a virulent strain of heat-killed bacteria when mix with a non-virulent strain of bacteria then the non-virulent bacteria transforms into virulent bacteria. Later it was proved that DNA was the material that transfers from virulent strain to non-virulent strain and transform it into virulent strain.
So as DNA is the genetic material that passes from one generation to another and one bacteria to another not protein therefore after mixing a heat-killed phosphorescent strain of bacteria with non-phosphorescent living strain, DNA must be passed to living strain from heat-killed strain to gain phosphorescent ability.
Therefore the right is A) DNA passed from the heat-killed strain to the living strain.
The tropical rainforest is one of the world’s most threatened biomes, despite being home to some of the most diverse and unique species on the planet. Many of the world’s most colorful creatures reside in rainforests, and animals from tiny organisms to large wild cats find homes amongst the range of plant life.
For many years tropical rain forests were safe from the presence of man, other than native tribal individuals who lived harmoniously with the land, but the problem of man’s encroachment on rain forests for lumber, agriculture, and development is having serious effects on the long-term survival of these regions.
