Answer:
At each higher level of consumption, the amount of toxin is magnified.
Explanation:
 Those predators all eat smaller secondary consumers, and those secondary consumers eat the primary consumers, which a lot of the times are exposed to DDT. For example bugs are often the primary target for DDT, once those bugs are exposed to the DDT they carry it in/with them. When a fish eats the bug, that fish is now exposed to the DDT. When the fish is caught and eaten by an eagle that eagle and its young are now being exposed to DDT. The DDT might not effect the full grown eagle for its lifetime but it does effect its young.

Answer:
Higher heat of evaporation required to break hydrogen bonds
Explanation:
Water molecules are joined together by intermolecular hydrogen bonding. Evaporation of liquid water into water vapor requires extra energy to break these hydrogen bonds to separate the water molecules from each other. 
Since a higher heat of evaporation is required, the water molecules absorb the heat from the skin surface or leaf surfaces during perspiration and transpiration respectively. This leaves the cooler skin and leaf surfaces behind. Therefore, the presence of intermolecular hydrogen bonds and the need for extra energy to evaporation water allow it to exhibit a cooling effect.
