In 1927, the geneticist Hermann Muller exposed living fruit flies to X-rays. He found that the fruit flies' offspring displayed dramatic mutations. Muller concluded that the X-rays damaged chromosomes. What was the independent variable in Muller's experiment?
-
The X-rays
-
The fruit flies
-
The mutations
-
The chromosomes
Correct Answer
A. The X-raysExplanation
In Muller's experiment, the independent variable is the X-rays. This is because the X-rays were deliberately manipulated and controlled by Muller in order to observe their effects on the fruit flies and their offspring. The independent variable is the factor that is changed or manipulated by the researcher in an experiment to see its impact on the dependent variable, which in this case would be the mutations observed in the fruit flies' offspring.Rate this question:

Tony observes that corn seedlings will bend toward a light source. He grows 150 corn seedlings. He then removes the tips from 50 seedlings, covers the tips of another 50 seedlings with aluminum foil, and leaves the last 50 seedlings alone. He puts all the seedlings near a strong light source and observes them for 3 days. Which hypothesis is Tony testing?
-
If a seedling is watered, it will always grow toward the light.
-
If a seedling is exposed to a light source, the seedling will bend toward the light.
-
If the tip of a seedling is removed, the seedling will die, even if exposed to light.
-
If light does not reach the tip of a seedling, the seedling will not bend toward the light.
Correct Answer
A. If light does not reach the tip of a seedling, the seedling will not bend toward the light.Explanation
Tony is testing the hypothesis that if light does not reach the tip of a seedling, the seedling will not bend toward the light. He conducts an experiment where he removes the tips from 50 seedlings, covers the tips of another 50 seedlings with aluminum foil, and leaves the last 50 seedlings alone. He then observes all the seedlings near a strong light source for 3 days. By comparing the growth and bending patterns of the different groups of seedlings, Tony can determine if the presence or absence of light at the tip affects the seedlings' ability to bend towards the light.Rate this question:

An inference is
-
A logical interpretation of data.
-
The same as an observation.
-
A statement involving numbers
-
A way to avoid bias
Correct Answer
A. A logical interpretation of data.Explanation
An inference is a logical interpretation of data because it involves drawing conclusions or making predictions based on the information or evidence that is available. It requires analyzing the data and using reasoning to come to a logical conclusion. Inferences go beyond simple observations, which are just statements of what is directly observed, and they also do not necessarily involve numbers or calculations. Inferences are important in many fields, such as science and research, where they help to make sense of data and draw meaningful conclusions.Rate this question:

To be useful in science, a hypothesis must be
-
Measurable
-
Testable
-
Observable
-
Correct
Correct Answer
A. TestableExplanation
A hypothesis must be testable in order to be useful in science. This means that it must be possible to design experiments or gather data that can either support or refute the hypothesis. If a hypothesis is not testable, it cannot be proven or disproven through scientific methods, and therefore it is not considered valid in the scientific community. A testable hypothesis allows scientists to conduct experiments and gather evidence to support or reject the hypothesis, ultimately contributing to the advancement of scientific knowledge.Rate this question:
