The diagram below represents 4 species of Bacteria. Which statement is correct concerning the chances of survival for the species if there is a change in the environment? Captionless Image A) Species A has the best chance of survival because it has the most genetic variation B) Species B has the best chance of survival because it has no genetic mutations C) Neither species B nor D will survive because they will compete for the same resources D) None of the species will survive because bacteria reproduce asexually

Answer:

a has most genetic variation

Think of examples of how the following parts of natural selection exist within mice populations:

Overproduction-

Competition-

Variation -

Selection-

A group of scientists wants to observe the adaptation of a foreign fish species in a river ecosystem. To do this, they want to enclose the top and sides of a section of a river to block light and matter from entering the area. Evaluate whether this experimental system is an isolated system. Justify your answer based on the definition of an isolated system.
