When blood flow is gone from the extremities for too long, the cells start to die. Depending on the severity of the damage, new cells will either replace the old or that part of the body that is lost to frost bite. Which system was MOST responsible for frostbite?
Those that knew Randy stated he should not have gone treasure hunting because he had a premedical breathing condition known as asthma from a long life of smoking. Asthma causes severe difficulties in breathing when under stress or mild exercise and can lead to death or serious injury without treatment. If Asthma was indeed the reason for Randyâs death instead of frost bite, which system would be MOST responsible?
Blood pressure typically rises during the winter due to constrictions in blood flow, which can lead to an increase in heart attacks, strokes, and other cardiovascular causes of death. Scientists at the Oregon University have uncovered a system that tells the body when to perform one of its most basic defenses against the cold: Shivering. The scientists have discovered the brains wiring system, which take temperature information from the skin which tells the brain when the musculoskeletal system should start shivering. Which system was primarily responsible for initiating Randyâs shivering if frostbite was his cause of death?
The _______________system was triggered when Randyâs blood flow was limited in response to the severe cold temperatures, this led to his brain to send impulses through the ______________ system to constrict blood vessels in the circulatory system and cause shivering. This is the bodyâs first line of defense in response to Frost bite.

Scientists are studying the effects of climate change on the Baltic Sea. Some scientists predict that if current trends continue, the Baltic Sea will become less salty, and it will contain less dissolved oxygen. Because of these changes, the Baltic Sea will have less biodiversity. The location of the Baltic Sea is shown on the map below.

The white-tailed ptarmigan lives at high elevations on mountains that receive a lot of snow in the winter. During the summer, the ptarmigansâ feathers are mottled brown. The birds lose the brown feathers and grow a new set of white feathers during the winter. Scientists are concerned that rising global temperatures will affect the white-tailed ptarmigan.
If global climate change leads to the elimination of snow in the habitat of the white-tailed ptarmigans, which adaptation is most likely to occur over many generations?
Lake Victoria in East Africa is home to many species of fish called cichlids. In 1954 the predatory Nile perch was introduced to Lake Victoria. The Nile perch became the dominant fish species in the lake by the mid-1980s. The number of cichlid species in the lake decreased as the Nile perch population increased. The perch preyed heavily on the cichlid species that fed on the algae and debris on the bottom of the lake. Algae in the lake increased, and oxygen levels decreased. The surface area of the gills of some of the cichlid species has increased in just over 20 years.
Which statement explains the increase in gill surface area seen in some of Lake Victoriaâs cichlids?
