Scientists use radio technology in order to track endangered species. These include radio collars, tags and chips. These devices can then be tracked wither via satellites through GPS technology or by locating the radio waves emitted by these devices using receivers.
These devices have proven very helpful in tracking organisms and monitoring their populations.
Some frogs are slimy because they are covered in a mucous coating. This coating helps them keep their skin moist which helps them breathe through their skin. The mucous often contains other chemicals, like antibacterial or anti fungals to help protect the frog.

The bare soil surface type affects the amount of runoff because it has
no other stopping mechanism that prevents runoff to happen. Just like in the
use of pesticide, it is
harmful to human agriculture because it contains an antifreezing chemical
(present in transportation vehicles). When the chemical seeps into the soil, it
will create a runoff and can seep into the groundwater causing pollution.

The best answer is A
Saltwater fish are hypotonic to their surroundings. This means their blood has a higher water concentration than the surrounding sea water.
Due to the fact that there is more salt and less water outside their bodies, there is a tendency to take in salt and lose water.
To counter this, salt water fish drink a lot of the sea water and urinate very little. Special cells in the gills actively eliminate salt at the cost of extra energy and these fishes do not absorb any salt from the water they drink.
Answer:
Biodiversity or Biological diversity is a term that describes the variety of living beings on earth. It is described as degree of variation of life. Biological diversity encompasses microorganism, plants, animals and ecosystems such as coral reefs, forests, rainforests, deserts etc.
-In biodiversity, each species, no matter how big or small has an important role to play in ecosystem. It represents the wealth of biological resources available to us. It’s all about the sustaining the natural area made up of community of plants, animals, and other living things that is begin reduced at a steady rate as we plan human activities that is being reduced by habitat destruction.
