The population of bacteria in a petri dish doubles every 12 h. the population of the bacteria is initially 500 organisms. how long will it take for the population of the bacteria to reach 800?

0.096 hours which when multiplied gives you 5 hours

Explanation: Initially the population is 500 organisms which is the 0 hour,then do the following calculation:

800 x 0.06 ÷ 500 = 0.096

The 0.06 comes from:

1000x ÷ (500x12) = 0.06

Plato

Asian elephants are more closely related to mammoths because they share more nodes and branches on the phylogenetic chart. This relationship suggests a closer evolutionary ancestry. Mastodons and Paleomastodons are not the same species. There are branches from Paleomastodon and Mammuts that suggest speciation occurred. Mammuts also have common evolutionary ancestors that Paleomastodons do not have.
