Francesco Redi performed his experiment against the theory of spontaneous generation. In his experiment, he takes one glass jar and a piece of flesh and analyzes them in three different situations.
<h3>Why did Francesco Redi perform his glass jar experiment?</h3>
Francesco Redi performed his glass jar experiment in order to illustrate the evidence against the theory of spontaneous generation.
He demonstrate that dead maggots or flies would not generate new flies when positioned on rotting flesh in a sealed jar, whereas live maggots or flies would have the capability to grow some eggs of maggots.
This experiment discredited both the presence of some essential components in once-living organisms and the requirement of fresh air to induce living life.
The complete question is as follows:
Which choice best summarizes the outcome of Redi‘s experiment?
- Evidence for the theory of spontaneous generation.
- Evidence against the theory of spontaneous generation.
- Evidence for the theory of special creation.
- Evidence for the theory of the origin of life.
Therefore, the correct option is B, i.e. Evidence against the theory of spontaneous generation.

A chemosynthetic bacteria is a producer. Chemosynthetic bacteria produce energy by using chemical reactions similar to photosynthesis but without the light as a catalyst. A chemosynthetic bacteria can produce organic molecules (i.e. glucose) from inorganic molecules just like photosynthetic organisms.
<span>Excess nitrogen is brought in the pond from the fertilizer, which are ladden in nitrogen and phosphorous, and rain water or running water takes that nitrogen to the water bodies.Bacteria must have come from the sewage disposal in the pond. Sewage is rich in organic material and allows proliferation of bacteria, which is taken to the pond when the sewage is disposed in the pond.</span><span />
Answer:
Physical changes can easily be reversed but chemical changes cannot because in physical change only state is changed while in chemical change, new substances are formed. For example, when water in liquid form is condensed, it changes into solid form (ice). It is a physical change because water in liquid and solid have the same chemical formula only arrangement of molecules are different. Burning of wood is a chemical change because new substances i. e. carbondioxide and heat is produced.
