Question

1 multiple choice 2 points a student investigated the effect of temperature on the germination of radish seeds. he thought that exposure to high temperatures would limit the seeds ability to germinate. since it could denature proteins needed for growth. three hundred seeds were soaked in distilled water for one hour. they were then divided into three groups. one group was placed in an oven set to 450 degrees f for 10 minutes. another group was placed in an oven set to 200 degrees f. the last group was kept at room temperature. the seeds were then planted in three separate flats and given the same amount of water. the flats were placed in a location with a constant temperature of approximately 70 degrees f. each day for two weeks the number of seeds that germinated in each group was recorded. total number of bean seeds germinated after being placed in the oven. 200 degrees 450 degrees room temperature 54 26 88 which group is the control group in this experiment? 0 degrees room temperature 450 degrees 200 degrees 2 multiple choice 2 points how can drawing a conclusion in science be different from making a guess? making guesses is more fun than drawing conclusions. they are the same thing. conclusions are based on evidence and data, while guesses are not. guesses are always correct, but conclusions are often wrong.

Explanation:

1. In an experiment, the control group is the one that is not exposed to the experimental treatment. Here, the group kept at room temperature is the control as it has no special temperature - related treatment (unlike the groups at 200 and 450 degrees).
2. In science, a conclusion is a statement that is derived from evidence (such as data from an experiment). A guess, on the other hand, is an unfounded prediction.

Answer:

1. Room temperature
2. Conclusions are based on evidence and data, while guesses are not.
