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
Answer:
it tells us that it is the change in the characteristics of a species over several generations and relies on the process of natural selection
Explanation:
Natural Selection: The process where organisms have better adapted to their environment and tend to survive and produce more offspring than those without the adaptations
With that dictionary definition we know that we develop certain characteristics in order for survival. The characteristics are developed over multiple generations. One example is that we have a part of our body that we needed before, but no longer need as we don't need to be immune to poisonous foods (or that's what our body tells us)
It's found in the chloroplast

<em>Correct option: </em><em>D</em>
