Exam 2: Principles of Science and Systems

The ability of an ecosystem to recover from a disturbance is known as

The statement, "Since every insect I have examined so far has six legs, I conclude that all insects must have six legs" is an example of

The progress of science is mainly happens when a scientist working in isolation and discovers something very important.

An important value of science is that it provides the methodology to prove that a theory is correct.

In experimentation, dependent variables are also known as _____________ variables.

Susan is conducting an experiment to see if plants will grow better with application of fertilizer. She separates 50 plants into two groups of 25. One group receives a liquid fertilizer when watered every other day, and the other group receives only water on the same days. The plants are kept in a greenhouse with constant and equal amounts of sunlight, and a constant temperature. She measures the plants once a week for 12 weeks. At the end of 12 weeks, the plants with the fertilizer grew an average of 9 inches, and the ones that were not given the fertilizer grew an average of 5 inches -In the scenario described above, the plants that received fertilizer are the _______________ group, and the plants that did not receive fertilizer are the ___________ group.

Which of the following scenarios are free from bias?

In a food chain, grass absorbs sunlight to make sugar, the grass is eaten by a rabbit, and the rabbit is eaten by a fox.What is a throughput that connects this system?

_________________ is a process for producing knowledge methodically and logically.

Ideally, science

From the following statements and questions, which is the best example of deductive reasoning?

Proof in science is always

Double-blind studies are especially useful in

A scientific consensus

At the end of 12 weeks, the plants with the fertilizer grew an average of 9 inches, and the ones that were not given the fertilizer grew an average of 5 inches. -In the above scenario, why did Susan place the plants in a greenhouse and control the amount of sunlight and temperature?

The damage to an ecosystem caused by a hurricane or flood can be referred to as

Experiments in which conditions are deliberately altered and all other variables are held constant are known as ___________ experiments.

Which of the following is a closed system?
