Explanation:

Spontaneous generation was the idea that living things could come from non - living things. Francesco Redi tested if meat would turn into maggots. In the flask experiment, when broth was heated in a flask with intact neck, bacteria didn't grow; when neck was broken, bacteria grew. This disproved spontaneous generation, showing living things come from other living things (biogenesis). Unicellular organisms are made of one cell. When DNA comes from two parents, it's sexual reproduction. The genetic code is the sequence of nucleotides in DNA or RNA that determines the amino - acid sequence of proteins.
