1. Which of the following studies include 2 factors in their study? Indicate the two factors used if the answer is YES. a) A certain study delved into the effects of magnetic fields on cell dedifferentiation, or the loss of the cells' ability to become specialized cells, in bread wheat. The study used two wheat genotypes and three levels of magnetic field strength. The results show that the differences between wheat genotypes and two levels of magnetic strength were significant for some treatments related to callus indication. b) The effect of temperature on the growth of a bacteria under accurately controlled conditions has been examined in an apparatus which permits food to be supplied at any desired rate by means of an automatic syringe mechanism. Six temperatures were used, from 15° to 40° at 5° intervals, with a single rate of food supply. Total and viable cell counts were frequently made and growth curves constructed. c) A certain study aimed to understand the growth and plankton abundance in aquaponics culture. Completely Randomized Design (CRD) was employed with two treatments in triplicates. The treatments are treatment A (positive control using organic liquid fertilizer) and B (drip irrigation aquaponics with a water debit of 100 ml/day/plant).

1. Which of the following studies include 2 factors in their study? Indicate the two factors
2. A study was conducted to determine the growth performance of swine among varying
levels of protein supplements (20% and 40%) and percent of cassava root (20%, 30%, 40%)
as additive in rice bran. All the levels of factors were purposively selected. The treatment
combinations were randomly assigned to swine of the same initial weight. Percent gain in
weight were obtained after 2 months. Suppose all the assumptions for the parametric test
were satisfied. What treatment structure was used in this experiment?
used if the answer is YES.
