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.

Ans 6:

Fe facts:1) Ostriches have wings, though it is not used for flying.2) Bats do not have feathers. They have hairs like other mammals.3) Emu has wings and again not used for flying.4) A penguin has feathers.5) Almost all birds have wings and feathers.So, option D is the only one that seems right.

Ans 3:

Class : Class 9
We fry stuff in oil because oil has much higher boiling point in comparison to water. So after heating when oil reaches temperatures greater than the boiling point of water (100 C) it instantly vaporize the water present in food into steam. ... Oil fries it and gives a crispy texture.
