Answer:
Gypsum and limestone.
Explanation:
Mining of valuable stones such as gypsum and limestone occur in my location. These valuable stones are used in the formation of beautiful tiles and in painting materials. Due to extraction of these valuable stones, erosion of the land occur as well as air pollution increases by the use of machines for extracting these minerals so it caused adverse affect on the environment so this mining has to be limited in order to both save the environment and get benefits from these minerals
Answer: Rosalind Franklin discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick's suggestion that DNA is a double-helix polymer in 1953.
Explanation:
The most observable difference is the way in which cytokinesis occurs. In plants a new cell wall is fashioned between the new daughter cells, while in animal cells the cell membrane constricts to pinch the parent cell into daughter cells.
It would be uracil (C)
thymine would be complementary to adenine in DNA but because it is RNA it is replaced by uracil.
