<span>Globally, diversity naturally has increased over time, though the great mass extinctions have decreased it for a while. The most famous of the mass extinctions is the one that claimed the dinosaurs, but we are currently in the midst of a human-created mass extinction. Local diversity, on the other hand, is constantly increasing and decreasing at very short time scales. There are many factors that affect diversity, and the major natural circumstances are given here. Human-generated impacts on diversity have almost always been negative, and are covered in the Conservation Issues section.</span>
Answer:
this is my lazy guess but: human activity, differences in emitted energy from earth, and natural fluctuations. BUT DONT TRUST ME LOOK IT UP IM NOT SMART
Answer:
I think it's Gene, maybe!
If a pathogen penetrates the first line of defense, the nonspecific internal defenses (as part of the second line of defense) it will possibly encounter are: an inflammatory response and neutrophils.
If a pathogen able to somehow pass through the the barriers shielding the body, one of the first active responses of the innate immune system is triggered. It is termed as an inflammatory response.
The major role of an inflammatory response is to set up a physical barrier against the spread of an infection.
Neutrophils are the phagocytic cells which move throughout the body in the blood. They are generally the first immune cells to show up at the site of an infection.
