What is the independent variable of an experiment?
The independent variable is how each jar is covered. The dependent variable is the amount of maggots in each jar. The control groups are Jar1( no covering, left open), and Jar 2 (covered with netting). The experimental group is Jar 3 Sealed from the outside).
What is the control group in Redis Experiment?
the control was the open jar with meat
What is a personal decision that invoes science?
Does eating meat contribute to health problems.. Apex Which experiment to do.
What is the controlled variable in redi's experiment on spontaneous generation?
The jar that contained the meat with the cover on it.
Francesco Redi disproved the idea of spontaneous generation through an experiment involving?
meat and flies
What equipment did use in his experiment?
Redi used meat, glass jars, and gauze. He put 2 pieces of meat in 2 different jars, and covered one jar with the gauze.
What equipment did Redi use in us experiment?
Redi used meat, glass jars, and gauze. He put 2 pieces of meat in 2 different jars, and covered one jar with the gauze.
Why was the gauze important in redi's experiment?
Redi used a jar, meat and gauze. The gauze kept the flies off the meat. Redi's hypothesis was that if you kept flies away from the meat, maggots would not appear, because the flies did not lay eggs on the meat.
What equipment did redi used in his experiment Why was the gauze important?
Redi used Meat and Jars and the guaze was important becasue it was covering the flies away form the meat.
Why was the gauze important?
The gauze kept the flies off of the meat.
What variables present in redi's experiment on spontaneous generation is not a controlled variable?
The presence of living organisms in the meat jars was not a controlled variable in Redi's experiment on spontaneous generation. This variable was dependent on the conditions set by Redi, rather than being controlled by him.
In redi's experiment what were the manipulated variable and responding variable?
In Redi's experiment on spontaneous generation, the manipulated variable was the presence or absence of gauze on the jars to prevent flies from accessing the meat, while the responding variable was the presence or absence of maggots developing on the meat.
Why francisco redi disprove the sponteneuos origin of life?
Francesco Redi disproved the spontaneous origin of life by conducting an experiment with jars containing meat. He showed that maggots only appeared in the jars where flies had access to the meat, while the jars covered with gauze to prevent flies from landing on the meat did not produce maggots. This experiment demonstrated that life does not arise spontaneously but is generated from pre-existing life forms.
What was Redi's experiment?
Francesco Redi's experiment in the 17th century involved placing meat in jars, some covered with gauze and some left open, to test the idea of spontaneous generation. He demonstrated that maggots did not spontaneously appear on the meat in the covered jars, disproving the prevailing theory at the time.
What is the independent variable of an experiment?
The independent variable is how each jar is covered. The dependent variable is the amount of maggots in each jar. The control groups are Jar1( no covering, left open), and Jar 2 (covered with netting). The experimental group is Jar 3 Sealed from the outside).
What is the appropriate control in an experiment on the effect of heat on meat?
Unheated meat.
What did Francesco Redi discover?
Francesco Redi did an experiment in 1668 that disproved a belief that maggots spontaneously generated on rotting meat. His experiment was to place meat into sets of jars: one set he left open to the air, one set he covered with very fine gauze, one set was completely sealed. Maggots appeared on the meat in the open jars; flies laid eggs on the gauze but no maggots appeared because the scent of rotting meat provides no nourishment; nothing appeared on the meat in the completely sealed jars. Redi believed in spontaneous generation of many things, just not fly maggots. He is credited with beginning the experiments using controls method used now.
