<span> When a frog catches an insect, it throws its sticky tongue out of it’s mouth and wraps it around its prey. The frog’s tongue then snaps back and throws the food down its throat.</span>
"The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top."
Oldest to youngest: Layer B, Layer C, Layer A
The oldest is always at the bottom, the youngest layer is at the top
Each layer contains the square of the layer number.
<span>So,
Let's figure out :
1 squared = 1 </span>
<span>2 squared = 4 </span>
<span>3 squared = 9 </span>
<span>4 squared = 16 </span>
<span>5 squared = 25
</span>6 squared = 36
<span>Hence,
The total number of oranges in the pile = 1+4+9+16+25+36
= 91 oranges
</span><span>
D. 91</span>
