Answer: <u>Option C, they digest pathogens</u>
Explanation: Monocytes are involved in the process of digesting pathogens and infected cells, termed as phagocytosis.
Monocytes don't produce antibodies, only B cells can produce antibodies. So, option A and D are incorrect. Also they appear colorless when observed under the microscope. They don't appear granular, so option B is also incorrect.
The answer is behavioral isolation.
Reproductional isolation is a way to prevent closely related species to mate each other. This is due to reproductive barriers which can be either prezygotic (before fertilization) and postzygotic (after fertilization) barrier. Behavioral isolation is an example of postzygotic barrier. It is based on behavior, including mating sounds and rituals. Thanks to behavior isolation, the different species (in this example gentoo penguins and emperor penguins) will have different mating rituals so they could attract only individuals of their own species, respectively.
Error is the amount of imprecision or variation in a set of measurements. It is expressed as a percent error. So the statement is true! Hope this helped!
