Ivanovski's work with the tobacco mosaic disease demonstrated that a pathogen smaller than a bacterium was responsible for the disease. This finding challenged the existing notion of pathogens being solely bacteria, leading to a shift in the germ theory to include entities smaller than bacteria, eventually paving the way for the discovery of viruses.

What is evolution best categorized as?
Evolution is best categorized as a scientific theory that explains how species change over time through the process of natural selection and genetic variation. It provides a framework for understanding the diversity of life on Earth.
What is one widely accepted theory in life science?
One widely accepted theory in life science is the theory of evolution by natural selection, proposed by Charles Darwin. This theory explains how species change over time through the process of natural selection, where organisms best adapted to their environments are more likely to survive and reproduce.
What does Darwin theory predict?
Darwin's theory of evolution by natural selection predicts that species will evolve over time through the process of natural selection, with traits best suited for survival and reproduction becoming more common in a population. This theory explains how biodiversity arises and how species are adapted to their environments.
Charles Darwin originally published the idea that all species have descended over time from common ancestors. This idea is known as evolution. Evolution is best categorized as?
Evolution is best categorized as a scientific theory that explains how species change over time through a process of natural selection, genetic variation, and adaptation. It provides a framework for understanding the diversity of life on Earth and how species have evolved to their current forms.
Are there multiple theories of evolution?
No- only one. Darwin's Theory of Evolution: •Natural Selection says that better qualities of a specie goes to the next generation and the species becomes better over time; the species that fitted the nature best; served to make new species through mutation and cross breeding.

Which theory, such as the trichromatic theory or opponent process theory, best explains color vision in humans?
The trichromatic theory best explains color vision in humans. This theory suggests that there are three types of cones in the retina that are sensitive to different wavelengths of light, allowing us to perceive a wide range of colors.

Which theory of light best explains the interference of light?
The wave theory of light best explains interference phenomena, where light is considered to propagate as a wave. This theory posits that when two waves overlap, they can either reinforce (constructive interference) or cancel out (destructive interference) each other depending on their relative phases. This accounts for the patterns observed in interference experiments.
