Answer 1

Answer:

Neither of them are correct.

Cynobacterium is the prokaryote which grows on the fur of polar bears.

Answer 2

Answer:

Nostoc is a Cyanobacterium which grows on the fur of polar bear.

Explanation:

• The prokaryote that develops on polar bear fur is called cyanobacteria.
• Cyanobacteria are prokaryotic, which means they lack a distinct nucleus and membrane-bound organelles.
• Typically, such species are bacteria.
• Cyanobacteria, on the other hand, are not harmful to polar bears, whereas bacteria typically cause illnesses.
• These bacteria are photosynthetic.
• They live in colonies within the polar bears' fur.
• The polar bear's white fur acquires a yellowish-green hue from this bacteria.
• Polar bears may blend into their surroundings thanks to their white fur. In arctic circumstances, their coat is so well-camouflaged that it occasionally appears to be a snow drift.
