Answer:

The correct answer will be options-B and D

Explanation:

The studies on the history of origin and evolution of life on Earth shows that all the organisms have evolved from a common descendant. This indicates that they possessed the same chemical-genetic or heredity molecule called Nucleic acid whether DNA or RNA.

DNA acts as the universal genetic material as it is present in all organisms except few. The process related to the DNA molecule is the same in all the organisms.

Since in the given question, the transfer of genes to plants via <em>Agrobacterium</em> and then the expression of the gene in plants shows that the passing of DNA has no barrier as  DNA is the genetic material and the enzyme RNA polymerase recognized the gene which could help produce the mRNA from the gene.

Thus, options-B and D is the correct answer.

den301095 [7]

Answer:

Prokaryotes are important to all life on Earth for a number of reasons.

Explanation:

They play a critical role in the recycling of nutrients by decomposing dead organisms and allowing their nutrients to be re-used.

They are also important for many metabolic processes. Bacteria in our guts and mouth help with the digestion of food by breaking down difficult to digest carbohydrates and other compounds. Recent research has suggested that the microbial community in our guts can be a significant factor contributing to obesity.
