Early coal miners used canaries in cages as an early warning system to detect dangerous air
blagie [28]

Answer:

Because the Arctic glacier is crucial in cooling the land.

Explanation:

The glaciers contained in the Arctic are essential for cooling the earth's climate, which is why Arctic conditions are so important in determining the earth's climate changes.

These glaciers reflect about 80% of the sunlight in the northern hemisphere, and can cool the region's climate. If Arctic glaciers melt, most of the sun's rays will be absorbed by the ocean, increase the temperature and increase the melting of the glaciers.

As a result, the entire ecosystem will be damaged.

The endosymbiotic theory proposes that eukaryotic cells arose as a result of large cells engulfing smaller, aerobic bacteria. th
lina2011 [118]

The organelle that provides evidence for this theory is the mitochondria and the chloroplast.

<h3>What is the endosymbiotic theory?</h3>

The endosymbiotic theory is the theory which describes how the eukaryotic cells arose from simple prokaryotic cells.

In the endosymbiotic theory states that when two prokaryotic cells with several abilities came together, one engulfed the other and existed in a symbiotic relationship that enabled  the cells to meet their needs for survival an growth.

The mitochondria and the chloroplast provides evidence for the endosymbiotic theory.

In conclusion the endosymbiotic theory describes  how eukaryotic cells arose from simple prokaryotic cells.
