the graph. 6.1 dN = rmax N (K-N) dt K ANS: “dN/dt” in the equation above is a differential calculating notation that represents instantaneous change in population size (N) over time (t). 6.2 ANS: When the population size (N) approaches the carry capacity (K) and N=K then the equation is rewritten as such: dN = rmax K (K-K) dt K 6.3 ANS: Therefore when (N=K) then dN/dt = 0. When dN/dt = 0 then the population

DNS zones are categorized by where information is stored, whether they are able to be written to, and the type of data they send and receive. Zones can be kept in an Active Directory or in text files. Primary Zones- are a zone that hosts a read and writes copy of the DNS zone in which records are produced and administered. Only one primary server per zone is allowed, and only this server loads and hosts the master copy of the zone. In addition, this server is also the only one allowed to process
