Answer:

Greenhouse gas emissions could cause a 3°-6°C increase in mean land surface temperature at high temperatures and temperatures latitudes. Despite this, few experiments have isolated the effects of temperature for this scenario on trees and forests. This review focuses on tree and forest responses at boreal and temperate latitudes, ranging from the cellular to the ecosystem level. Adaptation to varying temperatures revolves around the trade- off between utilizing the full growing season and minimizing frost damage through proper timing of hardening in autumn and dehardening in spring.

Answer:

- Trichinosis

- Bacterial endocarditis

Explanation:

Trichinosis is a parasitic infection that has as its etiological agent the nematode parasites of the genus Trichinella, and the species of greatest interest to human medicine is Trichinella spiralis.  One of the first and characteristic symptoms of infection is the swelling of the eyelids, which appears around the 11th day after infection. Subsequently hemorrhages appear in the eye sclera and in the back of the eyes, eye pain and photosensitivity. Then there is the appearance of muscle pain, along with a rash and bleeding below the nails causing dark red vertical lines about 1 to 3 mm long. The pain is intense in the muscles linked to breathing, chewing and swallowing.

Bacterial endocarditis is always associated with a bacteremia that the immune system has failed to counteract. In other words, the presence of bacteria in the bloodstream, which is usually sterile, represents an important cause of bacterial endocarditis, an infection that affects the inner membrane lining the heart and heart valves, especially if they already have a disorder. The disease sets in when bacteria from various parts of the body - from the mouth mainly, but also from the skin, intestines, respiratory tract, and urinary tract - are carried through the bloodstream to a heart valve or other damaged endocardial area where fix it. Among the many symptoms, indicative of the presence of this disease in the body are thin dark red vertical lines about 1 to 3 mm long in the nails.
