Bats have wings and no feathers. Ostriches and Emus have both feathers and wings, but they can’t fly mainly due to their huge size. Penguins have feathers and flippers (not wings). “A” is incorrect as bats doesn’t have feathers. “B” is incorrect as penguins doesn’t have wings. “C” is incorrect as there are birds that has both feathers and wings. “D” is the correct answer

Ans 16:

Organism X is actually emu, because it has wings AND feathers. So correct answer is D.Answer B however is wrong, as it tells emus ONLY have feathers. Answer C is wrong as organism X can be any bird, even penguins. And answer A is also wrong as bats don't have feathers and ostriches have wings too.

oil has a low boiling point than water. Therefore we use oil to make the cooking process faster and easier
