Answers for Bio Practice w/s.The practice w/s is tittled Quiz 4 and Quiz 5.
Quiz 4 : From Cells to Organisms
Section A:
1. B
2. D
3. B
4. B
5. C
Section B:
1 (ai)(1) Skeletal tissue [½ mark]
(2) Muscular tissue [½ mark]
(ii)(1) Animals require a structure that provides support (skeletal tissue) to keep it upright whereas plants are supported by cellulose and turgor pressure.
(2) Animals move and require muscles for movement whereas plants are stationary and do not need muscles [1]
(b) Name Function Organ
Respiratory system Transport air in and out of the body[1]
Lungs[½]
Nervous system[½]
Allows the transmission of messages[½], in the form of Brainelectrical impulse[½], around the body for communication [½]between different organs[½]
Digestive system[½] Breaks down food[½] so that they can be absorbed by the Stomachbody[½]
Circulatory system[½] Transports blood around the body[½] to allow all tissues to Heartreceive oxygen and food[½]
2 (i) Red Blood cell.
(ii) Transport oxygen around the body.
(iii) Contains haemoglobin/acucleated/bioconcave[any 1]
(iv) Haemoglobin can bind reversibly with oxygen/ lacks nucleus so can pack in more haemoglobin/ bicomcave so it has a large SA:VOL to allow for faster diffusion of oxygen into the cell [any 1 with resepect to anwer in (iii)][1 mark each]
Quiz 5: Diffusion /OsmosisSection A
1. A
2. D
3. C
4. B
5. C
Section B
1(a) Movement of molecules from a region of higher concentration to a region of lower concentration[½], down a concentration gradient[½]
(b) Movement of water molecules from a region of higher water potential to a region of lower water potential[½], through a partially permeable membrane.[½].
(c)It is the movement of substances across a cell membrane against a concentration gradient[½], using energy[½] from respiration.
(d) Diffusion OsmosisMovement of molecules Movement of water molecules onlyPresence of partially permeable membrane Partially permeable membrane must be is not needed present
2(ai) distilled water
(aii) Diluted salt solution
(aiii) Concentrated salt solution
(bi) Water in solution move into the potato[½]because the solution has a higher water potential than the potato cells[½].
(bii) Water potential of solution inside and outside X is the same[½], thus no net osmosis of water[½]. Thus no change in length.
(biii) Water in potato move out[½] because the solution has a lower water potential than the potato cells[½].
(c) Ensure accuracy of result.
3(a) Sugar molecules are smaller[½] than pores of the membrane whereas starch are larger[½] than the pore of the membrane.
(bi) Membrane burst[1]
(bii) Process: OsmosisExplanation: Since the sugar molecules are unable to diffuse out, the solution in the visking tubing has a lower water potential than the solution in the beaker[½]. Thus water move in by osmosis until the membrane can no longer hold the excess water[½] and burst.
