Abiology student is studying ways to grow crops in soils that are high in salts and other dissolved solids. to determine whether corn plants can tolerate salty soil conditions, she grows one corn plant in typical non salty soil and one corn plant in the same soil plus 0.5 kilograms of salt. after 6 weeks of growth, the corn plant grown in salty soil is only about 50% of the mass and height of the corn plant grown in non-salty soil. how can this research be improved so that she will have greater confidence in her data?

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
