    Study Notes

    Biology - Zoology for 2014 Syllabus

    • This biology paper is designed for students who are enrolled in the 2014 syllabus.
    • It covers the subject of zoology
    • Total marks for the paper: 35
    • The duration is 2 hours
    • Students are required to answer all questions, and must illustrate their answers with labeled diagrams and examples wherever necessary.

    Group A

    • Questions in this group are multiple choice and focus on various aspects of biology, including hormones, cell structures, reproductive systems, and disease transmission.
    • Answers should be chosen from the provided options.

    Hormone Questions

    • Question 1(a) asks about the hormone secreted by Leydig cells.
      • Options: Vasopressin, Gonadotropins, Oxytocin, Testosterone.
      • The correct answer is Testosterone.
    • Question 1(b) asks about the origin of the acrosome in a spermatid.
      • Options: Nucleus, Mitochondria, Golgi bodies, Ribosome.
      • The correct answer is Golgi bodies.
    • Question 1(c) asks about the infective stage of Plasmodium Falciparum.
      • Options: Sporozoite, Trophozoite, Cryptozoite, Merozoite.
      • The correct answer is Sporozoite.
    • Question 1(d) asks about the term Mendel used to denote a unit responsible for character transmission.
      • Options: Chromosome, Elementle, Factor, Gene.
      • The correct answer is Factor.
    • Question 1(e) asks about the phenomenon involved in nerve impulse conduction.
      • Options: Biochemical, Biophysical, Electrical, Electrochemical.
      • The correct answer is Electrochemical.

    Fill in the Blank Questions

    • Question 2 presents a series of statements with underlined portions that require completion.

    Group B

    • This section assesses knowledge regarding various biological processes and concepts.

    Essay-Type Questions

    • Students are required to answer any four questions from this group, using two to three sentences for each answer.
    • Each answer should be concise yet informative.
    • Question 3(a) asks about the significance of crossing over.
      • This involves the exchange of genetic material between homologous chromosomes.
      • It promotes genetic diversity and variation in offspring.
    • Question 3(b) asks about the formation of the AIDS provirus.
      • The AIDS retrovirus, HIV, upon entering a host cell, uses its reverse transcriptase enzyme.
      • This enzyme converts its RNA genome into DNA, which then integrates into the host cell's DNA, forming the provirus.
    • Question 3(c) provides a statement about the giant honey bee, Apis mellifera.
      • The giant honey bee is known for its honey production.
      • It is a species of honey bee commonly used for honey production.
    • Question 3(d) asks about the genotype of a carrier of haemophilia.
      • Haemophilia is a recessive sex-linked disorder.
      • Carriers, typically females, have one normal X chromosome (X) and one X chromosome carrying the recessive haemophilia gene (X").
      • Their genotype is therefore represented as X" X.
