Tetraploid organism or the cell that has four sets of chromosome in their cell whereas diploid organism that contains two sets of chromosome in their cell. The fertile diploid and fertile tetraploid organism produce triploid organisms that are sterile in nature.
This cross would result in the triploid and the gametes will have uneven chromosome numbers in it that will not let the sexual reproduction possibly occur.
The correct answers are ATMOSPHERE and BIOSPHERE. Nitrogen is most abundant in the ATMOSPHERE, but nitrogen can't be absorbed by the BIOSPHERE without the help of a special bacteria and without undergoing a process called nitrogen fixation.
The experimenter hypothesized that fertilizer would make the plants grow taller. The results show that, on average, plants with fertilizer grew 0.7 cm taller over the course of 12 days. This small amount of height increase could be attributed to the fertilizer or may be caused by natural differences in the plants.
