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

Deamination occurs mostly in the brain. T/F
ki77a [65]

The answer is false.

Deamination is the process (reaction) in which an amine group is removed from a molecule of amino acid. The enzymes that are involved in this reaction are called deaminases. Deamination can be used for energy(break down of amino acids), when there is too much protein intake. Amine group is converted to ammonia that is then converted to urea or uric acid in the urea cycle and at the end excreted through the urine.

In the human body, deamination occurs mostly in the liver (e.g. urea cycle), but also in the kidneys (deamination of glutamate).

bija089 [108]

Answer:

The biological carbon cycle

Autotrophs capture carbon dioxide from the air or bicarbonate ions from the water and use them to make organic compounds such as glucose. Heterotrophs, or other-feeders, such as humans, consume the organic molecules, and the organic carbon is passed through food chains and webs.
