Answer:
The idea of spontaneous generation was disproved by Francesco Redi.
Explanation:
- Spontaneous generation is a theory that states that living organism can generate from an inanimate object.
- In, 1668, Francesco Redi demonstrate an experiment explaining the theory of spontaneous generation by using meat.He noticed that flies laid eggs on meat which was kept open and maggots developed.
- He took three pieces of meat to do the experiment.
- The first piece of meat was kept open and as usual maggot development takes place.
- With the 2nd piece of meat,he covered it with a piece of cheesecloth and noticed that,flies lay eggs on the cheesecloth but when he removed the cloth,maggot did't form.
- Next, he took a piece of paper and cover the meat piece, and he noticed that flies did't lay any eggs and thus no maggots formed.
This is because the active
site of the receptors on the cell and the hormone are akin to lock and key
respectively. The conformations of the receptor’s active site and the hormone allow them to
interlock with specificity. The receptor (which is a transmembrane protein) is
connected to second messengers inside of the cell that triggers a biochemical
cascade in response to the hormone.
It was proposed in 465BC.
