Answer:
The correct answer is convergent evolution.
Explanation:
The wings of bats, butterflies, and most birds are the example of analogous structure. Analogous structures are the structures which are similar in appearance and function but have separate evolutionary origin.
They are similar superficially because they experienced a natural selection that evolved them to have that shape which helps them to fly. Analogous structures are produced due to convergent evolution.
Convergent evolution describes the presence of the same trait in unrelated species. Therefore the correct answer is convergent evolution.
Inner core, outer core, mantle and crust
Answer:
1. when there is a cut, the surface area of the skin becomes rough which activates the Thrombin, that catalyzes the activation of fibrinogen present in plasma.
2. albumin contributes mostly of making plasma protein
3. albumin contributes the major portion to the osmotic pressure of plasma.
4. fibrinogen mainly forms the structural framework of a blood clot during blood coagulation.
Answer:
The right answer is A
Explanation:
Because animals take in sugar and oxygen, break them down and release carbon dioxide and water along with ATP as usable energy.
Answer: -plants
-animal waste
Explanation:
Fossil fuels are the fuels which are generated after a long time taking geological process over the buried organic matter obtain from dead animals, animal dung and plants. The organic matter remain under the heap of earth crust under intense heat and pressure. The heat and pressure generate fuels which are valuable for the entire society as when they are burned they produce huge amount of thermal energy. These includes the crude oil like petroleum, natural gas and coal.
