How has a rise on global temperature impacted the life of the polar bear? A rise in temperatures has disrupted the Arctic food c

hain common to polar bears. Key to maintaining a healthy weight and insulative fat layer is a diet of seals. The US Geological Survey suggest that if such trends continue, two-thirds of the world's Arctic ice could disappear by 2050. The accumulation of greenhouse gases in the Earth's atmosphere has been substantially increased by the combustion of fossil fuels. Scientists predict that malnourishment among the bears resulting in smaller litter sizes will result in their extinction in several decades. As a result of melting sea ice, there should be more vegetation on-shore for the polar bears to eat.

Answer: A rise in temperatures has disrupted the Arctic food chain common to polar bears.

Explanation:

Global warming is the sustained increase in the average temperature of the earth, sufficient to cause climate change.

This rise in temperature has denied polar bear the presence of ice caps, that they usually get on in their hunts for seals. Consequently, the Arctic FOOD CHAIN has been disrupted, as polar bears are less likely to feed on seals

Note that other options DO NOT give the impact of global warming on polar bears

What are four characteristics of a good extraction solvent?
ella [17]

A good extraction solvent should have a strong solubilizing capability for the compound of interest, it should be immiscible or only weakly misciblewith the matrix solvent ( the first solution or mixture containing the compound from its natural source, e.g., water/ether. water/ chloroform, etc. If possible the extraction solvent should be non-flammable, non-toxic or of low toxicity, reasonably volatile, and of low eco-impact. Inexpensive and available, of high purity , and shelf stable. If one is determining the compound of interest by UV/Vis spectrophotometry or fluorescence, the solvent should have extremely low absobance or emission at the wavelength of analysis

Answer:

negative feedback

Explanation:

The negative feedback system is the most common in the body, being considered by many authors the primary mechanism for the maintenance of homeostasis. It causes a negative change from the initial change, that is, a stimulus contrary to the one that led to the imbalance. In the case of the above question, when the ambient temperature increased, your body began to sweat to lower the temperature, that is, your body is trying to make a stimulus contrary to what is happening in the environment, so we can state that your body is going through a negative feedback system.
