<span>Water has a surface skin. Some insects are able to generate tiny bubbles under their bodies which makes them buoyant enough to not break thru the water's skin. This skin is also known as surface tension. </span><span>Some bugs and small objects (pins or paperclips, etc) can rest on the surface of the water due to surface tension. Water molecules are bipolar and attract each other forming a skin. The bug or paperclip make tiny depressions in the water skin which provides buoyancy. A detergent will ruin the water tension (because it is a wetting agent) and the bug or paperclip will sink.</span><span>

Match the creature to its distribution pattern.
lorasvet [3.4K]

Answer:

The correct match would be:

  • Swallow - migration
  • Tiger - sparse distribution—scarce
  • Devil’s Hole pupfish - local endemic
  • Humpback whale - sparse distribution—widely dispersed

Swallows are small migratory birds belonging to the family Hirundinidae found all around the world. Migrating swallows can cover around 200 miles in a day.

Tiger has become endangered species due to excessive hunting and habitat loss. It is estimated that only 3800 tigers are left in the wild.

Devil’s Hole pupfish is a species of a fish only found in Devils Hole which is a  geothermal aquifer-fed pool located in Ash Meadows National Wildlife Refuge  in Nevada city of the United States

The humpback whale or <em>Megaptera novaeangliae</em> is a species of baleen whale which is widely distributed in all major oceans including Pacific, Atlantic, and Indian oceans.
