While Louis Pasteur was the one that procured the germ theory of disease that explains that diseases are caused by microorganisms, the first researcher that provided direct experimental data to support the said theory is Robert Koch.
Robert Koch developed a criteria for the causality of disease from microorganisms called the Koch's postulates. The Koch's postulates indicate that:
(1) The bacteria must be present in every case of the disease
(2) <span>The bacteria must be extracted and isolated from the host with the disease and should be directly visualized and/or grown in culture
(3) There must be a healthy experimental host that will reproduce the disease once the isolated bacteria is injected
(4) The bacteria should be recoverable from the previously healthy host

Answer:
The correct option is B) adaptation
Explanation:
The features and properties of an organism that make it favourable to live in an environment are termed as the adaptations of that organism. Over time, evolution occurs and organisms with better adaptations survive as they are better suited to live in a particular environment. The light-coloured moths were adapted to live on Earth when the colour of the trees had not gone dark. With time, as the colour of trees got darker, the moth had to change colour to be better adapted to live on Earth.
Answer:
Inputs for the Electron Transport Chain are NADH, H+, ADP, FADH2, O2. Outputs: NAD+, ATP, FAD, H2O. 1)
Producers are very important to ecosystem reason being without the producers we would not be able to survive. Producers make their own food by use of sun which turns simple raw materials into food.
Herbivores are consumers who eat only green plants. Omnivores eat animals and plants. Scavengers only eat dead organisms. Scavengers help the environment in that they eat dead organisms and decomposes the broken organic material down to the raw material.
