Answer:
Regarding pathogens, the statement that is true is that viruses cannot reproduce on their own.
Explanation:
Viruses are pathogenic agents not considered as living beings, since they are only constituted by genetic material surrounded by a viral capsid, besides not fulfilling vital functions.
These agents are unable to reproduce on their own, so they need to place their genetic material —DNA or RNA— inside a host cell, to modify its nuclear DNA and be able to reproduce.
The other options are not correct because:
- <u><em>Influenza can cause an upset stomach</em></u><em>. Influenza primarily affects the respiratory system.</em>
- <u><em>Pathogens affect everyone equally.</em></u><em> Each individual's immune response is different when exposed to the same pathogen.
</em>
- <u><em>Fungi are large, stoneflies organisms</em></u><em>. The pathogenic fungi, such as Candida albicans and Trichophyton, are different from the mushrooms and fungi that can be seen in soil or decomposed organic matter.</em>

Answer: Interferons
Explanation:
Interferons can be defined as the cells that is already being virus affected and they release some chemicals out of it in order to prepare the cells or to enhance the cells for anti-viral response.
The cells a group of signaling proteins which is being released by the host cells in response to the presence of virus in the body.
Chemically they are cytokine molecules which is used as a defense mechanism to protect the other cells of the body from being infected.
Certain response like fever, muscle pain are caused by the interferon.
