Compare the effectiveness of molecular diffusion in a simple organism (unicellular) versus a multi-cellular organism. What are the limitations of diffusion and how do multi-cellular organisms overcome these problems?
Homework Answers
Simple organism - Diffusion more effective over only in small
distance.
Simple organism have Surface area / volume ratio is large. So,
diffusion is of nutrients pass very fast in the membrane.
Multi cellular organisms - Surface area / volume ratio is small. So, the diffusion is very low in the membrane.
The limitation of diffusion - based on size, shape, and function
of cells. Diffusion occurs only over small distances so it limits
size and shape of the cells.
The multi-cellular organisms overcome these problems by using
carrier protein by active process using ATP or against the
gradient.

LAB EXERCISE #6: Kirby-Bauer Disk Diffusion Test for Antibiotie Sensitivity Determination The Kirby Bauer Test is an agar diffusion test that is used to determine the effectiveness of antibiotics killing various species of bacteria. Filter paper disks saturated with the antibiotic of interest are placed a Mueller-Hinton agar plate on which bacteria that has been isolated from a clinical sample has been sarcad. The antibiotic then diffuses from the disk...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
