Welcome back to our Examination Paper Analysis<\/strong> series!<\/h2>\n

Recently, one of my students shared with me that he encountered difficulties while attempting this interesting experiment-based question from the 2019 P6 Rosyth School (ROSYTH) Prelim<\/strong> Examination Paper<\/strong>.<\/p>\n

This question is about finding out how the amount of dissolved oxygen in water affects various types of organisms in the water, which I would share and discuss with everyone in today\u2019s blog post!<\/p>\n

We have been learning that organisms need to take in oxygen for respiration to release energy to survive. However, do ALL organisms need oxygen to survive, and if not, which organism does not?<\/p>\n

Do read on to find out! \ud83d\ude4a<\/p>\n\n

Question Analysis<\/h2>\n

Let\u2019s take a look at Q14.<\/p>\n

Thought Process<\/h2>\n

Here is a brief summary of what this question is about:<\/p>\n

    \n
  1. This is an experiment-based<\/strong> question on how the amount <\/strong>of dissolved<\/strong> oxygen <\/strong>in water affects various types of organisms<\/strong> in the water.<\/li>\n
  2. The organisms are placed in two containers, one with<\/strong> more dissolved oxygen<\/strong> than normal and the other one with less dissolved oxygen<\/strong> than normal.<\/li>\n
  3. Students are then asked to choose the option<\/strong> that best represents the number of organisms left in each container with different amounts of oxygen<\/strong>.<\/li>\n<\/ol>\n

    After reading the question, does anyone have their answer in mind yet? For those with an answer in mind, were you all deciding between options (2) and (4)?<\/p>\n

    If you did, am I right to say that your thought process is as follows?<\/p>\n

    \"\"<\/p>\n

    For those of you who chose either (2) or (4) as the answer, sadly, both options are incorrect<\/strong>!<\/p>\n

    What is wrong with the thought process above in answering this question?<\/p>\n

    The crux is that you answered the question using your own knowledge<\/strong> and DID NOT use the information given in the question<\/strong>, leading you to apply the wrong concepts to this question.<\/p>\n

    Thus, to avoid using the wrong concepts, I always advise my students to execute the following steps when tackling questions:<\/p>\n
