Draw the Core
Label if you’re able
Annotate if you’re great

Draw the Core
http://sciencevideos.wordpress.com Draw the Core 2
This presentation is for practice with assessment statements where
you need to draw, label, annotate or where a diagram would be very
helpful to describe, outline or identify.
One slide has the assessment statement. The next has the diagram
and the last has the diagram with labels.
How could you use it in your revision?
• QuickDraw flashcards – can you draw the item in the statement?
• Labeling practice – can you add the correct labels?
• Explain, outline, annotate, describe practice. Take the diagram or
image and use it to help in your treatment of objective 2 and 3
assessment statements.
This is a work in progress – but you might
find it useful. It will be updated later.
The diagrams in the presentation are all creative commons (unless otherwise noted), which means you can
share, edit and print them, as long as you cite the source as http://sciencevideos.wordpress.com.
Remember:
It’s an exercise in
clarity, not a
colouring-in
competition!
Assessment statements have been taken from the online IB Biology subject guide:

Drawing in IB Biology Exams

7. (a) Draw a labeled diagram showing the ultrastructure of a typical prokaryote. [4]
• You can use pencil and a ruler.
• You must not use coloured pencils.
As of 2011, exams will be scanned and look like this:
This bit gets cut off
The scanning machine only looks inside the boxes, so stay inside!
Use extra paper if needed, but include a note to that effect in this box.
Make sure the extra paper is labeled clearly.
• Draw clearly! Not too light or messy.
• Practice first on the scrap paper.

At low temperature:
Increase in temperature
increases rate of reaction.
At high temperature:
Increase in temp. leads to
sharp decline in rate as
enzymes are denatured.

Light intensity
At low light intensity:

K
Transition phase
I + N > E + M (but less so)
Increased competition as space
and resources are used up. Rate
of population growth slows.
Exponential phase
I + N > E + M
Abundant space and resources. Very little
competition so reproduction is high.
Plateau phase
I + N = E + M
High competition as space and
resources are limited. High effect
of natural selection.

Draw The Core

  • 1. Draw the Core Label if you’re able Annotate if you’re great Stephen Taylor http://sciencevideos.wordpress.com Draw the Core 1
  • 2. Draw the Core http://sciencevideos.wordpress.com Draw the Core 2 This presentation is for practice with assessment statements where you need to draw, label, annotate or where a diagram would be very helpful to describe, outline or identify. One slide has the assessment statement. The next has the diagram and the last has the diagram with labels. How could you use it in your revision? • QuickDraw flashcards – can you draw the item in the statement? • Labeling practice – can you add the correct labels? • Explain, outline, annotate, describe practice. Take the diagram or image and use it to help in your treatment of objective 2 and 3 assessment statements. This is a work in progress – but you might find it useful. It will be updated later. The diagrams in the presentation are all creative commons (unless otherwise noted), which means you can share, edit and print them, as long as you cite the source as http://sciencevideos.wordpress.com. Remember: It’s an exercise in clarity, not a colouring-in competition! Assessment statements have been taken from the online IB Biology subject guide: http://xmltwo.ibo.org/publications/migrated/production-app2.ibo.org/publication/7/part/2/chapter/2.html
  • 3. Drawing in IB Biology Exams http://sciencevideos.wordpress.com Draw the Core 3 7. (a) Draw a labeled diagram showing the ultrastructure of a typical prokaryote. [4] • You can use pencil and a ruler. • You must not use coloured pencils. As of 2011, exams will be scanned and look like this: This bit gets cut off The scanning machine only looks inside the boxes, so stay inside! Use extra paper if needed, but include a note to that effect in this box. Make sure the extra paper is labeled clearly. • Draw clearly! Not too light or messy. • Practice first on the scrap paper.
  • 5. A Terrible Drawing… http://sciencevideos.wordpress.com Draw the Core 5 Too light Unlabeled Messy Tiny
  • 7. A Rubbish Drawing… http://sciencevideos.wordpress.com Draw the Core 7 Where are these labels pointing? The arrow heads are unnecessary Unclear labels Outside the scanning box Messy shading Criss-crossed label lines Wiggly label lines
  • 9. A Good Drawing… http://sciencevideos.wordpress.com Draw the Core 9 • Good use of space • Clear strong lines • Label lines are straight • Labels clearly written • Scale bar if appropriate • Lines touch the labeled structure • No unnecessary shading or colouring
  • 10. http://sciencevideos.wordpress.com Draw the Core 10 2.2.1 Draw and label a diagram of the ultrastructure of Escherichia coli (E. coli) as an example of a prokaryote. All assessment statements taken from the online IB Biology subject guide: http://xmltwo.ibo.org/publications/migrated/production-app2.ibo.org/publication/7/part/2/chapter/2.html

At high temperature: Increase in temp. leads to sharp decline in rate as enzymes are denatured. Rateofreaction Rateofreaction Rateofreaction Light intensity At low light intensity: Increase in light intensity increases rate of reaction. At high light intensity: Increase in light intensity has no effect on rate of reaction – plateau. CO2 concentration At low [CO2] : Increase in [CO2] increases rate of reaction. At high [CO2] : Increase in [CO2] has no effect on rate of reaction – plateau as all active sites are filled.

Day 14-28 Endometrium maintained by high progesterone levels to prepare for fertilisation. endometrium Day 0-14 FSH and LH stimulate development of the oocyte (egg) in the ovary. Day 14 peak of LH causes ovulation. Day 15-28 FSH and LH inhibited by estrogen and progesterone, preventing further release of eggs. Day 0-14 estrogen increases, building the endometrium. Day 14-18 estrogen drops, progesterone peaks, maintaining endometrium and inhibiting FSH and LH. Day 28 Progesterone drops if the egg is not fertilised and does not implant onto endometrium.
