BIOMAGNIFICATION LAB REPORT AIM The aim of this lab is to model bioaccumulation and biomagnification through a food chain. MATERIALS 100 M&M’s Paper towel to lay M&M’s on 20 small cups labelled “zooplankton” 5 medium cups labelled “minnow” 2 larger cups - one labelled “eel #1”‚ and another labelled “eel #2” 1 bowl labelled “osprey” PROCEDURE The pile of M&M’s represents the phytoplankton population in a lake. The printed “M” on the candy represents the amount of DDT (in ppm)

Light Microscopy Lab Lab write-up 1 Parveen Rajper Biology 101 Principles of Biology 1 September 29‚ 2012 Introduction: The light microscope helps see the microscopic world that the naked eye cannot see. If there were no microscopes in the world‚ than it would be very difficult to understand the many particles that surround the living world. The purpose of this lab experiment is to become familiar with a microscope. It is hypothesized that it will be difficult

His mistress was a kind-hearted woman who was glad to educate Douglass‚ but her under her husband’s influence she became fierce and ceased to instruct him. What Douglass means when he writes that “education and slavery were incompatible with each other” (paragraph 2) is they are mismatched and do not apply with each other. A slave cannot be educated or intelligent because when a person is “a slave for life‚” (paragraph 7) they have no

These rate especially the 600rpm and the 300rpm are then used to calculate PV (deals with the total solids) and YP (deals with the carrying capacity of the mud)‚ the gel is related to the gel strength which deals with the suspended capacity. From analysis when heated as compared to when at room temperature the PV and

California. Laboratory agar looks gelatinous because it is dissolved in boiling water and cooled. Agar can be easily distinguished from the other materials commonly found in a laboratory due to its distinctive smell. At room temperature‚ agar is a gel and it stays firm at 65ºC and melts at 85ºC. It solidifies when the temperature reaches 32 – 40ºC. It is used as various microoragnisms’ culture medium‚ especially for bacteria and it is also served as a thickening for soups and sauces‚ in jellies and
