The correct answer is;

2. less than 15 s

Explanation:

Grahams law of effusion states

$\frac{Rate 1}{Rate2} =\sqrt{\frac{Molar Mass2}{MolarMass 1} }$

Therefore

we have molar mass of neon gas = 20.18 g/mol

Molar mass of nitrogen gas = 28.014 g/mol

Which gives

$\frac{Rate 1}{15} =\sqrt{\frac{20.18}{28.014} }$ = 0.72

Therefore the rate of effusion of nitrogen gas is 0.72*15 = 12.73 s which is less than 15 s

It's camouflage which allows it to hide in places where the skin can be matched with the leaves or bushes and the predators won't get them easily and get tricked
