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.

Day 0 5 14 28 Day 0-5 Endometrium is broken down (menstruation) as progesterone falls. Day 5-14 Estrogen rises, endometrium builds. 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. Luteinising hormone (LH) Follicle stimulating hormone (FSH) estrogen progesterone
