Name the types of burns one can get and which structures of the integument are damaged

First degree burns include only the outer layer of skin, otherwise known as the epidermis. Skin in this condition is usually red in appearance, and can be quite painful. An example of a first degree burn injury is a common sunburn. The skin will be dry, and healing usually occurs in 3-5 days. The injured epithelium peels away from the healthy skin during the healing process, and hospitalization is only required if the pain is intolerable or there is a fluid imbalance.

Second degree burns are further divided into two subcategories: partial thickness and full thickness. In partial thickness second degree burns, there may be blisters present and the injury will involve the epidermis and upper layers of the dermis. The wound will be pink or red in color, extremely painful, and may appear wet. This type of burn heals in several weeks without grafting and scarring is usually minimal.

Third degree burns are the most severe type. All layers of the skin are destroyed and the damage extends into subcutaneous tissues. Areas can appear black or white and will be dry or leathery in texture. The wound will not blanch when pressure is applied, and there is no pain involved because the pain receptors have been destroyed along with the rest of the dermis.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.
