Question

Question;1.;List two differences observed between plant and;animal cells. (2 points);2.;2. Describe the function of the following? (3;points);a. cell membrane;b. nucleus;c. flagella;d. mitochondria;e. chloroplasts;f. ribosomes;3.;Distinguish between an osmoconformer and an;osmoregulator. (2 points);4.;List two ways that osmoregulators maintain the;balance between their internal salt and water concentrations. (2 points);5.;5. If a freshwater cell were placed in;saltwater, would that cell increase in size, decrease in size, or stay the;same? Explain the reasoning. (4 points);6.;6. If a marine cell was placed in freshwater;would that cell increase in size, decrease in size, or stay the same? Explain the reasoning. (4 points);8. a. Did the volume of the potato cores placed in the;distilled water increase, decrease, or stay the same? (1 point);9. a. Did the volume of the potato cores placed in the 7%;solution increase, decrease, or stay the same? (1 point);11. While sitting at the front of the classroom, someone;walks in while wearing strong perfume. Within seconds, the smell is noticed by;other students in front of the room. A student sends a text message to a friend;in the back of the classroom who claims he cannot smell the perfume. Explain;why the smell will eventually reach him. Given enough time, what will;eventually happen to the perfume molecules? (4 points);12. While watching a special on animals, a student discovers;that hares tend to lose heat through their ears. Based on this and what is;known about surface-to-volume ratios, propose an explanation as to why hares;that live in hot climates (such as the desert) have large, extended ears. (4;points);15. (Appliation) How might the information gained from this;lab about osmosis be useful, or how can this knowledge be applied to everyday;life? (12 points)
