Answer:
The trees that have a thick, waxy coating on their surface of their needles, are found in the Taiga biome. The plant diversity is less in such ecology. The most common types of trees are the conifers. 
Adaptation of waxy coating and needles help them to retain water, and protect them from cold.

Answer:
Gain the attention of the audience
Explanation:
In any given speech it is of the utmost importance to establish contact with the public. Asking intriging questions is very effective and stimulates (by provoking human curiosity) the attention of the audience. Who can deny that he/she is tempted to continue to listen to a possible explanation of his/her own personal anxiety?

According to Cloward and Ohlin's theory, there are three subcultures juveniles may enter:
Criminal subcultures
Conflict subcultures
Retreatist subcultures
Criminal subcultures gear towards organized crimes, where they commit criminal acts to climb the social ladder in the criminal world and are rewarded through financial means. 
Conflict subcultures on the other hand tend to do less serious crimes, but instead use violence as a way to gain respect.
Retreatist subcultures turn to drugs and alcohol, seeing themselves as rejects.
With that, the answer would be Conflict subcultures or a conflict gang.
