A student conducted an experiment that used two rose plants to determine if a liquid formula for fertilizer was better than a
dry formula. He tested each fertilizer on a single plant for one month, and he concluded that the liquid formula was better.
When he described his conclusion to his teacher, she told him he needed to conduct additional trials. The teacher most
likely asked for additional trials because
ОООО
she did not believe the new formula helped plants grow better than the old formula.
it was necessary to see data from more plants before the conclusion could be accepted.
it was necessary to have tested the fertilizer on different kinds of plants.
she thought he should test additional fertilizer formulas on the same two plants.

It was necessary to see data from more plants before the conclusion could be accepted.

Explanation: It is important to conduct experiments multiple times before coming to a conclusion because there could have been an error when conducting the experiment. He should test out a liquid formula on one plant in a separate pot and the dry formula on another plant in another pot. He should also fertilize them equally to get accurate results.

its been noted for the past decade or so that there is some (approximately 5% to 7%) shrinkage in the brains of people who have schizophrenia, most notably in the gray matter, which is an important part structures in the brain’s amygdala, hippocampus and parahippocampus, which are all involved in memory storage and retrieval memory storage and retrieval.
