Answer:
B) Styrofoam is a good insulator.
Explanation:
When talking about thermal energy, or a heat, insulator is a material that doesn't allow heat to pass through easily. On the other hand, a conductor is completely the opposite, it allows, quite successfully, transfer of the heat.
So, regarding ice cream, from these definitions above, we can conclude that insulators will prolong melting time, while, in the conductors, ice cream will melt rather fast.
Looking at the table, we see that Styrofoam had the longest melting time, which makes it quite successful insulator.

Answer:
The correct answer is (B) A larger area of the sensory cortex is associated with our lips.
Explanation:
All the sensory inputs that come from the body is received by the somatosensory cortex. Neurons are responsible for sensing the perception of touch, heat, pains, etc on any body part and pass the information to the somatosensory cortex where the information gets processed.
Our lips contain many nerve endings and nerves which makes it very sensitive towards touch, warm, and cold. So due to the large number of nerve in lips it is considered as an erogenous zone which states that this area is very highly sensitive. So the correct answer is B.
