The student wants to know what gases are produced by the snails and Elodea in light and dark conditions. Assuming the student only has time for one experiment, what setup will yield the most complete data? All test tubes contain bromothymol blue. Experiment 1: Light room with test tubes A to D. A contains 1 snail. B contains Elodea. C is empty. D contains 1 snail and Elodea. Dark room with test tubes E to H. E contains 1 snail. F contains Elodea. G is empty. H contains 1 snail and Elodea. Experiment 2: Light room with test tubes A to D. Each test tube contains 1 snail. Dark room with test tubes E to H. Each test tube contains Elodea. Experiment 3: Light room with test tubes A to D. Each test tube contains 1 snail and Elodea. Dark room with test tubes E to H. Each test tube is empty. Experiment 4: Light room with test tubes A to D. A contains 2 snails and Elodea. B contains 1 snail. C and D are empty. Dark room with test tubes E to H. E contains Elodea. F contains 1 snail and Elodea. G and H are empty. a. Experiment 1 b. Experiment 2 c. Experiment 3 d.

Fittoniya [83]

(B) 25% GG, 50% Gg, and 25% gg

<u>Explanation:</u>

Given:

Green is dominant and is coded by G

Albino is recessive and is coded by g

Two corn plants that are heterozygous for color are crossed.

The heterozygous condition of the plant would be Gg.

The cross is shown in the table attached.

According to the punnett square drawn,

The genotypic ratio is 1 : 2 : 1 (GG : Gg : gg)

                                 = 25% GG , 50% Gg , 25% gg

Phenotypic ratio = 3 : 1 ( green : albino)

                           = 75% green, 25% albino

The researchers should look for patterns in their observations and provide an alternative explanation for the results which occurred. Based on the results and their understandings, they should further make another hypothesis and check for its authenticity.

In scientific researches, the results of a hypothesis generally do not get the expected results but this leads to new findings and discoveries.
