Spontaneous generation does not happen.
Rudolf Virchow was trying to advance the concept that diseases have cellular origin and proposed the idea that cells arise from pre-existing cells (omnis cellula e cellula). He aimed to show that diseases are caused by changes within cells themselves, rather than being caused by external factors. Virchow's work laid the foundation for modern cellular pathology and our understanding of the cellular basis of disease.
peeps used miroscopes! and found cells and did some more thinking and looking and they were clever.
Louis Pasteur was responsible for the development of the swan knecked flask experiment which effectively disproved the previously accepted theory that cells were spontaneously generated from non-living matter (abiogenisis- without reproduction of cells). Pasteur was alive from 1822-1895 and during that time people debated the issue with reference to how bacteria and mould could just "appear" on food and drink. Many believed that just because you boiled some broth and covered it to show that no bacteria grew did not prove that bacteria came flying in through the air,because boiling killed the "active substace" and air was also needed for spontaneous generation of bacteria. So pasteur developed the swan-knecked flask which allowed air in, but trapped any microorganisms in the bend of the kneck, preventing them from reaching the broth. He added beef broth to these swan-necked flask, boiled them to kill any microorgansms that may already be present, and left them sitting. Months and months later there was still no growth of bacteria. But when he broke the kneck of one flask, bacteria grew in the broth within days. Also in another flask, he tilted itover so broth could pour into the bend of the neck then he straightened it again. This flask also had bacterial growthwithin a few days. The experiment showed that if bacteria -already living cells- were allowed into the broth, then more bacteria could grow, but if they were trapped in the neck and never got to the broth, the broth remained clear and free from bacteria. It is said there is still a Louis Pasteur swan-necked flask with broth in it, with no bacterial growth in it, this many years down the track.
The products of respiration are Carbon dioxide, Energy and Water. The energy is used by all your body cells to carry out life processes. The Carbon Dioxide and Water are released when you breathe out. You can prove this by breathing into limewater-if it goes cloudy, Carbon Dioxide is present. Cobalt Chloride paper will prove water is present, as will the condensation if you breathe on a mirror!
Yeast is a living organism as it exhibits characteristics such as growth, metabolism, and reproduction. These can be observed through experiments showing yeast cells breaking down sugars to produce energy, forming new cells through budding or division, and responding to environmental stimuli. Additionally, yeast cells contain organelles like mitochondria and a nucleus, which are characteristic of living cells.

The theory of spontaneous generation was false.
It is what you are trying to prove
You start by speaking proper English. 'How do you prove you WERE'NT trying to break into someone's webmail?'
used to prove the analogous homologous characteristics of evolution
nothing
what are you trying to prove? if you were trying to prove a lemon can make lemonade the lemon can be used as a product to ensure that the theory is in fact "feasible"
