<u>Answer</u>:
C) They invade the body and can cause a humoral immune response.
This best explains the impact that pathogens in the environment might have on one's body.
<u>Explanation</u>:
Pathogens are the microorganisms that are found in the environment and have the tendency to cause diseases. The human body has various lines of defenses against the incoming pathogens, the Nonspecific responses keep the pathogens outside the body and these responses are common for all pathogens. If a pathogen manages to enter the body, then a series of specific responses are triggered which are focused on the type of pathogen.
The humoral response is a category of specific immunity and involves the substances found in body fluids. It particularly targets the newly invading pathogens. Hence, option C correctly describes the impact of pathogens on the body.
The correct answers (c.) punctuated equilibrium.Punctuated equilibrium is a mode of evolution that the certain foraminifera (shelled protozoa) represents. It is , in fact, the hypothesis of the evolutionary development of rapid episodes that is marked between long periods of little or even with no change at all.
