Biological transmission differs from mechanical transmission in that biological transmission involves reproduction of a pathogen
in an arthropod vector prior to transmission. works only with noncommunicable diseases. requires direct contact. occurs when a pathogen is carried on the feet of an insect. involves fomites
Biological transmission involves reproduction of pathogens in an arthropod vector prior to transmission. In terms of epidemiology, we can term a vector as an organism that is from infected to the uninfected. An infected organism which develops biological vector passes it to its host. For example a mosquito.
A mosquito being a mechanical vector carries an infected organism to its host either through the legs or through the other body parts
The type of information you are looking for is called confirmation/confirmatory biased information. (If I am misunderstanding the question, please correct me) Scientists sometimes skew the results or lie about the results in order to support their own personal beliefs or goals.
When the P680 special pair of photosystem II absorbs energy, it enters an excited (high-energy) state. Excited P680 is a good electron donor and can transfer its excited electron to the primary electron acceptor, pheophytin.
