What were the experiments that were used to explain the concept of spontaneous generation?
Francesco Redi - One of the first to disprove spontaneous generation. An Italian Doctor Who proved maggots came from flies. (Italian 1668) Lazzaro Spallanzani - One of the first to disprove spontaneous generation. An Italian scientist who proved microorganisms could be killed by boiling. (Italian 1767) Louis Pasteur - One of the first to disprove spontaneous generation. A French scientist who proved that micro organisms was carried by dust not air. (French 1864) In 1953 Miller and Urey experiment called as electric spark experiment shows how process of formation of organic compounds or first living cell formation occur.

ViviThe scientist's name was Francesco Redi. Anyways, the spontaneous generation experiment was carried out by a scientist (Redi), who hypothesized that organisms just popped out of nowhere (spontaneous). Previously, people rationalized that maggots popped out from meat. So the scientist set up an experiment. He placed two jars of meat outside. He covered one jar, and the other was left open. In a couple weeks time, one jar had maggots but the other did not. This disproved the idea of spontaneous generation. Check this out:

Explain how Pasteur's experiments showed that living things do not come from nonliving things?
Louis Pasteur's experiments demonstrated that living organisms do not spontaneously arise from nonliving matter. By conducting experiments with swan-necked flasks that prevented dust and microbes from entering the flask while allowing air to pass, Pasteur showed that microorganisms in the air were responsible for contamination and growth, not spontaneous generation. This contributed to the refutation of the theory of spontaneous generation and supported the idea of biogenesis, where living organisms arise from preexisting living organisms.
How did the theory of spontaneous generation explain the origin of simple life?
The theory of spontaneous generation proposed that simple life forms could arise from non-living matter spontaneously. It suggested that organisms like maggots could materialize from decaying matter without the need for pre-existing life. This theory was eventually discredited through experiments by scientists such as Louis Pasteur, who demonstrated that life only comes from pre-existing life.
Can the principle of probability explain the numerical results of Mendel's experiments?
This is true
What is spontaneous process explain the role of free energy in these processes?
A spontaneous process is one that occurs naturally without requiring any external influence. Free energy is a measure of the potential energy available to do work in a system. For a process to be spontaneous, the free energy change must be negative, meaning that the system moves to a lower energy state, increasing its stability. Essentially, free energy serves as a driving force for spontaneous processes by determining whether a reaction or process will occur on its own.
What questions did Mendel left unanswered?
Mendel's experiments did not address the underlying mechanisms responsible for the transmission of hereditary factors, known as genes. He also did not investigate the concept of genetic linkage or the role of chromosomes in inheritance. Additionally, Mendel's work did not explain the phenomenon of gene interactions or genetic interactions.
