Final Exam Diagrams

Question 1

Draw and label a motor neuron (and know the function of each structure).

Question 2

Draw and Label a half-view of an animal pollinated flower (and know the functions of each part too).

Answer 2

-sepals as outermost part of flower
-petals as largest part of flower
-stamen drawn with recognizable anther and filament
OR
anther and filament shown as parts of the stamen
-carpel/pistil drawn with recognizable stigma, style and ovary
OR
stigma, style and ovary shown as parts of the carpel
-nectary at base of the ovary
-ovule inside the ovary

Question 3

Label the structures of the human heart (and know the function of each).

Question 4

Label a diagram or x-ray of the human elbow joint (and know the function of each structure, including the movements of flexion and extension).

Question 5

Diagram of Oxygen Dissociation Curve

Answer 5

-diagram showing normal oxygen dissociation curve.
-diagram showing curve with increased CO2 to the right
-both axes correctly labelled
c. sketch/statement of S-shaped «oxygen dissociation» curve
-axes of graph labelled correctly as percentage oxygen saturation of hemoglobin on y-axis AND partial pressure of oxygen on x-axis
-curve shifted to right (and lower) for higher partial pressure /concentration of CO2 /lower pH

Question 6

Identify phases of the cell cycle based on a cyclin concentration graph (Review #1)

Question 7

Draw and label a diagram to show the structure of a membrane. (Review #1)

Question 8

Draw Prokaryotic and Eukaryotic (animal and plant?) cells (Review #1 and watch video on how to simplistically draw)

Question 9

Draw DNA double strand

Answer 9

-Purines (2 rings) always bind to pyrimidines (1 ring): A + T and G + C
-Hydrogen bonds form between bases to bind the two antiparallel strands of DNA together (forming a double helix)
-2 Hydrogen bonds form between A + T and 3 Hydrogen bonds form between C + G
