Summary

• Description:

  The MS Word document comprises Form 2 Biology Mid Term 2 Exam 2025 with Marking Scheme. The PDF version is also available upon your request.

  The marking scheme is in a different document.

  The exam paper, titled "FORM 2 BIOLOGY MID TERM 2 2025 EXAM" in the document, appears to have 14 main questions or question blocks (questions are numbered 1 to 13, with two questions labeled as 14). The total marks for the questions with specified marks and available text is at least 49 marks (Question 11a text is missing, so its marks are not included in this sum). The duration for the exam is not specified in the provided document snippet.

  The topics covered in the exam include:

  • Introduction to Biology & Classification:
    • Defining Taxonomy and Species.
  • The Cell:
    • Stating main functions of a microscope.
    • Functions and adaptations of the cell wall in plant cells.
  • Movement of Substances into and out of Cells:
    • Investigating a physiological process (likely osmosis) using a raw potato tuber and glucose solution.
    • Explaining results and observations in such an experiment.
    • Importance of active transport in living organisms and the role of oxygen concentration.
  • Nutrition in Plants and Animals:
    • Significance of chlorophyll, stomata, leaf midrib, and veins in photosynthesis.
    • Forms in which carbohydrates are stored in plant and animal tissues.
    • Calculating the number of teeth from a dental formula.
    • Explaining the result of bile duct blockage.
    • Identifying the process of peristalsis and the role of dietary components in food movement.
    • Distinguishing between homodont and heterodont dentition.
    • Stating the function of carnassial teeth.
    • Writing a dental formula based on given information.
  • Gaseous Exchange:
    • Explaining the differences in the percentage composition of carbon (IV) oxide and oxygen in inhaled and exhaled air.
  • Respiration/Energy Requirements:
    • Explaining why males may require more energy than females after a certain age (based on a table, though part of the question text for 11a is missing).
    • Naming other factors (besides sex and age) that determine energy requirements in humans.
  • Transport in Plants and Animals:
    • Distinguishing between single and double circulatory systems.
    • Naming defects of the circulatory system in humans.
    • Stating functions of blood other than transport.
    • Stating adaptations of xylem to water transportation.
  • Enzymes:
    • Accounting for the shape of a graph showing the effect of temperature on an enzyme-catalyzed reaction ( denaturation).
    • Identifying the optimum temperature for enzyme activity.
    • Stating other factors that affect the rate of enzyme-controlled reactions.
