SPM Biology – Answering Techniques in Paper 3 SPM Biology candidates typically commit the mistake of thinking that the length of their answered essay or structured questions equates to marks deserve‚ under the formula‚ Length of Structure Answer/Essay = Marks. This is wrong and Berry Berry Easy wishes to clear the air regarding this issue. It is never about how long you write but more about how accurate you write. So for Berry Readers who can write long answers but never seemed to score well‚

that decreasing levels of carbon dioxide correspond to increasing pH. Which cellular structure in elodea carries out the process that is most likely to result in increasing pH? Which structures‚ if found in a cell‚ would provide the best evidence that the cell is eukaryotic? Where in the cell do the following occur? Calvin cycle‚ glycolysis‚ Kreb’s cycle‚ electron transport chain. Students in a biology class tested the effects of antibiotics on the growth of bacteria. They cultured bacteria

Was it supported or refuted by their research? [2 marks] The author’s hypothesis was that‚ “ Carotenoids protect photosynthetic organisms against potentially harmful photooxidative processes and are essential structure component of the photosynthetic antenna and reaction center complexes”. The authors hypothesis was not supported

This is a practice test for biology 101 test 2. You should also review all lectures and practice writing questions for each lecture set. You will also want to take advantage of the test banks under the “Lessons” tab in Angel. In addition to these sample questions and the test banks‚ you are advised to study the diagrams from all chapters and be able to label main structures. 1) The function of the rough endoplasmic reticulum(RER) is: a) Digestion b) Support c) DNA isolation d)

Bacterial Biology █ BRIAN D. HOYLE An understanding of the fundamentals of bacterial biology is critical to bacteriologists and other forensic investigators attempting to identify potential biogenic pathogens that may be exploited as agents in biological warfare or by bioterrorists. Fundamentals of Bacterial Biology Bacteria are one-celled prokaryotic organisms that lack a true nucleus (i.e.‚ a nucleus defined by a membrane). Bacteria maintain their genetic material‚ deoxyribonucleic

AS Biology - Unit 1 ------------------------------------------------- Metabolism Metabolism is a term to describe all reaction which is taking place within a cell and is separated into two types which are * anabolic = compounds being built up * catabolic = compounds being broken down ------------------------------------------------- Water The water molecule is a molecule which is made up from 2 hydrogen atoms and 1 oxygen atom. It is bounded by 2 covalent bonds and has is polar.
