Innate immunity is a defense system that we are born with and that protects us against antigens. It is the sum of all defense mechanisms that occur naturally to protect an individual from infectious diseases. They are physiological mechanisms that are present throughout the entire animal kingdom and it is an inherent quality of each species.

Explanation:
The organism found in this domain is bacteria. Bacteria do not have cell walls. This is why we take anti-biotics, they attack the cell membrane of the bad bacteria since they have no wall to protect themselves
Answer:
UV radiation basically damages skin by transferring energy to molecules in your skin, such as DNA, fat, proteins, etc. These molecules, which are already in their proper arrangement, absorb this energy. If the molecules absorb enough energy, the bonds holding them together can break, forming a new shape completely. For a cell that already has been chugging along smoothly thanks to specific molecules with specific shapes doing specific jobs, this is a big deal and causes serious problems.
Explanation:
UV radiation damage to DNA is a particular problem. DNA is a huge molecule and actually quite fragile. When a molecule of DNA is present in a cell, it resembles a zipper: it has two strands, with each strand tightly bound to corresponding molecules on the opposite side, called bases.
