7) Part F) True or false? The water-soluble portion of a phospholipid is the polar head, which generally consists of a glycerol molecule linked to a phosphate group.
|
True |
|
False |
7) Part G) If a red blood cell is placed in a salt solution and bursts, what is the tonicity of the solution relative to the interior of the cell?
|
Isotonic |
|
Osmotic |
|
Hypotonic |
|
Hypertonic |
Homework Answers
7. True because thhe hydrophilic i.e water-loving portion of a phospholipid is the polar head and the hydrophobic portion is the non polar tail.
8.hypotonic. When the red blood cell is placed in a hypotonic solution it will bloat up and may explode because extracellular fluid has lower osmolarity then the fluid inside the cell

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...
