Redi went on to demonstrate that dead maggots or flies would not generate new flies when placed on rotting meat in a sealed jar, whereas live maggots or flies would. This disproved both the existence of some essential component in once-living organisms, and the necessity of fresh air to generate life.

In 1668, Francesco Redi, an Italian scientist, designed a scientific experiment to test the spontaneous creation of maggots by placing fresh meat in each of two different jars. Redi successfully demonstrated that the maggots came from fly eggs and thereby helped to disprove spontaneous generation.

The Francesco Redi Experiment. Francesco Redi was able to disprove the theory that maggots could be spontaneously generated from meat using a controlled experiment. Spontaneous generation, the theory that life forms can be generated from inanimate objects, had been around since at least the time of Aristotle.

Why is Redi’s experiment on spontaneous generation considered a controlled experiment? Redi’s experiment on spontaneous generation is considered a controlled experiment because throughout the experiment only one variable was changed at a time all other variables were kept unchanged or, controlled.

Francesco Redi’s hypothesis about the appearance of maggots was that flies produce maggots.

In Redi’s experiment, what were the manipulated variable and the responding variable? The manipulated variable was the presence or absence of the gauze covering, and the responding variable was whether maggots appear.

Louis Pasteur designed a procedure to test whether sterile nutrient broth could spontaneously generate microbial life. To do this, he set up two experiments. In both, Pasteur added nutrient broth to flasks, bent the necks of the flasks into S shapes, and then boiled the broth to kill any existing microbes.

There are three main variables: independent variable, dependent variable and controlled variables.

What is another word for experimental variable?

The response variable is the focus of a question in a study or experiment. An explanatory variable is one that explains changes in that variable. It can be anything that might affect the response variable.

What is another word for risk factor?

As nouns the difference between reason and factor is that reason is a cause: while factor is (obsolete) a doer, maker; a person who does things for another person or organization.

In algebra, simplifying and factoring expressions are opposite processes. Simplifying an expression often means removing a pair of parentheses; factoring an expression often means applying them.

Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The prime factors of a number or an algebraic expression are those factors which are prime.

Factors of a number are the numbers that divide the given number exactly without any remainder. According to the definition of factors, the factors of 18 are 1, 2, 3, 6, 9, and 18.

The gcf of 9 and 18 can be obtained like this: The factors of 9 are 9, 3, 1. The factors of 18 are 18, 9, 6, 3, 2, 1. The common factors of 9 and 18 are 9, 3, 1, intersecting the two sets above.

Yes, 11 is a prime number. The number 11 is divisible only by 1 and the number itself. For a number to be classified as a prime number, it should have exactly two factors. Since 11 has exactly two factors, i.e. 1 and 11, it is a prime number.

The first few prime numbers are as follows: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, and 199, etc.
