Explain what you mean and I can try and help
Van Leeuwenhoek discovered "protozoa" - the single-celled organisms and he called them "animalcules". He also improved the microscope and laid foundation for microbiology. He is often cited as the first microbiologist to study muscle fibers, bacteria, spermatozoa and blood flow in capillaries.
Concentrations of this toxin are found in the ant as well as in the lizard and the bird, as they are part of the same food chain. The lizard eats ants and the bird eats the lizard. This phenomenon is called biomagnification.
Biomagnification refers to the cumulative increase in concentrations of a persistent substance as one moves up the food chain (trophic chain).
Biomagnification is therefore a process in which the concentration of a substance present in a biotope increases throughout a food chain; by extension, the result of this process.
Answer:
1. The phrase Darwin used to describe his broad theory of evolution is *descent with MODIFICATION."
2. All of life is related through common ancestry, accounting for the "UNITY" of life.
3. The "DIVERSITY" of life arises from the adaptation of species to different habitats over long spans of time.
4. Darwin proposed a mechanism for how evolution occurs, which he called "NATURAL SELECTION"
5. Two key observations underlying natural selection are that members of a population vary in their "inherited traits"
6. Darwin inferred that those organisms with traits best suited to the environment ten to leave more "OFFSPRING" than other members of a population
7. This unequal reproduction in a population leads to the gradual accumulation of "adaptations" to the environment
