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.
