A city council must decide whether to ban the use of a pesticide that has been linked to declines in pollinator populations. To make an informed decision, they should consider the pesticide’s persistence, bioaccumulation potential, toxicity to non-target organisms, and the availability of safer alternatives. If a viable, equally effective, but non-persistent alternative exists, how should this impact the council’s decision? 

In P2P applications, each peer is operating as a server and a client at the same time.

With Persistent-HTTP, multiple objects can be sent over single TCP connection between client and server. 

An email user agent is located in an end system in the network edge, but an email server is located in the network core.

Compared with client-server architecture, applications with the P2P architecture can be self-scaling. For example, file distribution time with the P2P architecture is not linearly dependent on the number of peers while the one with the client-server architecture is.

True/False: Pearson Correlations can be used as long the outcome variable and predictor variable are the same type (i.e., either both continuous or both categorical).
