Mon-Day 1
Bio - REGENTS REVIEW SESSIONS begin this Wednesday immediately after school; we will quickly and efficiently analyze an entire Bio Regents exam, and GENERALIZE from each question. This will maximize your preparation and potential for success on the 2012 Bio/LE Regents exam.
explained the phenomenon of BIOMAGNIFICATION in which a non-biodegradable substance that is not excreted or egested, accumulates in greater and greater concentrations in higher level consumers due to overall decrease in biomass of each higher level (90% of biomass is lost due to excretion and other life functions).
We then began to discuss the observed phenomenon of ecological succession, which merely shows that organisms (biotic factors) that are best adapted to a nearly barren environment, can change that environment (its abiotic factors), thus making the environment habitable for more complex organisms that are adapted to the more fertile environment.
AP Chem - finished up our qualitative analysis observations.
