A cell is exposed to a substance that prevents it from dividing. The cell becomes larger and larger. This situation should present no problem to the cell since it can continue to perform all other necessary functions
should present no problem to the cell because the surface area of the cell will increase as the volume of the cell increases
will eventually be problematic since the cell's ability to absorb nutrients through its outer membrane will not keep
increasing as quickly as its cytoplasmic needs
O should be beneficial since the cell will be able to divert the ATP normally used for cell division to other processes

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
