Sebaceous Glands
Streptomyces and Penicillium produce antibacterial chemicals as a means of competition with other microorganisms in their environment. This allows them to gain a competitive advantage for resources and space. The production of these antibacterial chemicals increases their chances of survival and reproduction.
Specific defense refers to the immune response that targets a specific pathogen or foreign substance, utilizing specialized immune cells and proteins tailored to recognize and eliminate that particular threat. This type of defense provides a more targeted and efficient response compared to innate immunity.
Moles have hair on their bodies for insulation and protection. The hair helps regulate their body temperature and provides a layer of defense against predators and the elements.
The skin acts as the first line of defense against infection by creating a physical barrier to pathogens. It contains antimicrobial peptides and sebaceous glands that help protect against harmful microorganisms.
The epidermis tissue, which is the outermost layer of plant tissue, provides the most protection by forming a protective barrier against physical damage, pathogens, and water loss. This tissue is covered by a waxy cuticle that helps prevent dehydration and serves as a defense against environmental stresses.

The defense mechanism of the stag beetle larva is to excrete a secretion. They can also play dead if they fear they are in danger.

One example of a chemical defense in your skin is the secretion of antimicrobial peptides like defensins. These peptides help to kill bacteria and other pathogens on your skin's surface, providing a first line of defense against infections.
