*2025 UTME REGISTRATION TO START ON MONDAY, 3RD FEBRUARY, 2025.* The registration for the 2025 Unified Tertiary Matriculation Examination (UTME) will now commence on Monday, February 3, 2025, instead of Friday, January 31, 2025. This change is necessary to allow the Board to implement essential adjustments to its registration templates. These adjustments come in light of the recent suspension of certain law programmes at selected universities, as submitted to the Board by the Council for Legal Education. Additionally, the Board discovered that some Computer-Based Test (CBT) centres had used deceptive facilities to be approved, prompting the need for further scrutiny and corrections by disapproving such centres. The Board acknowledges the disruption this may cause to candidates and other stakeholders and sincerely apologizes for any inconvenience. The additional time will be used to ensure that all necessary changes are made for a smooth registration process. Fabian Benjamin, Ph.D Public Communication Advisor JAMB

Question 1 C. Is defined as the amount of energy required to remove an electron from an isolated atom or molecule G. Melting point and boiling point I. Faraday's second law of electrolysis states that if the same amount of electricity is passed through different electrolytes, the masses of ions deposited at the electrodes are directly proportional to their chemical equivalents.(2c) HOCL (hypochlorous acid) is acidic because it can donate hydrogen ions (H⁺) when dissolved in water. This release of H⁺ ions makes the solution acidic. On the other hand, NaHL (sodium hypochlorite) is basic because it is a salt formed from a strong base (NaOH) and a weak acid (HOCL). When NaHL dissolves in water, it produces hydroxide ions (OH⁻), which make the solution basic.

Questions 2 a(i). Random motion Negligible volume Elastic collision (c) HOCl (hypochlorous acid) is considered acidic because it readily donates a hydrogen ion (H+) when dissolved in water, while NaOH (sodium hydroxide) is basic because it readily dissociates in water to produce hydroxide ions (OH-) which are responsible for a basic solution. Key points: HOCl: When HOCl dissolves in water, it can release a hydrogen ion (H+) making it an acid. NaOH: When NaOH dissolves in water, it readily separates into sodium (Na+) and hydroxide (OH-) ions, making it a base.

(2a) UNDER PRIMARY SUCCESSION (i) Occurs in areas where no soil or vegetation existed before, such as after a volcanic eruption or glacier retreat. (ii) Starts from scratch, with no remaining vegetation or soil. UNDER SECONDARY SUCCESSION (i) Occurs in areas where soil and vegetation were previously present, but were disturbed or damaged, such as after a forest fire or clear-cutting. (ii) Starts with remaining vegetation, such as seeds, roots, or stumps.

(1ai) Homeostasis refers to the ability of the body or a system to maintain a stable internal environment despite changes in external conditions. (1aii) (i) Kidney. (ii) Liver. (iii) Pancreas. (1c)

(6a) Explanation of Reproductive Methods (i) Oviparity Oviparity is a mode of reproduction in which animals lay eggs that develop and hatch outside the mother’s body. The embryo receives no direct nourishment from the mother. Example: Birds, reptiles, amphibians. (ii) Viviparity Viviparity is a reproductive method where embryos develop inside the mother’s body and receive nourishment directly from her before birth. Example: Humans, mammals, some sharks. (6b) Three Classes of Oviparous Animals 1. Aves (Birds) – e.g., hen, pigeon. 2. Reptilia (Reptiles) – e.g., lizard, snake. 3. Amphibia (Amphibians) – e.g., frog, toad.

WAEC GCE BIOLOGY THEORY (4a) Image (4b) Type of Inheritance Illustrated The type of inheritance illustrated in this cross is -incomplete dominance. In this form of inheritance, neither allele is completely dominant over the other, resulting in a blending of traits in the phenotype of the offspring. (4c) Mechanism of Incomplete Dominance In incomplete dominance, the alleles for a trait blend together in the phenotype of the heterozygous offspring. In this case, the red allele (R) does not completely mask the expression of the white allele (r). Instead, when an R allele is combined with an r allele, the resulting phenotype is an intermediate color—in this case, pink flowers. This occurs because the expression of the alleles produces a phenotype that is a mixture of both parental traits, rather than one being dominant over the other. (4d) Test Cross with F1 Offspring A test cross involves breeding an individual of unknown genotype with a homozygous recessive individual to determine the genotype of the former. Let’s analyze the outcomes based on the F1 offspring (Rr), which are pink flowered. (4di) Genotype of the Parent The genotype of the parent used in the test cross is rr (homozygous recessive). (4dii) Phenotypes of the Result of the Cross The phenotypes of the result of the cross will be: - Pink flowers (Rr) - White flowers (rr) (4diii) Genotypes of the Result of the Cross The genotypes of the result of the cross will be: - Rr (pink) - rr (white) (4div) Genotypic Ratio of the Offspring Obtained The genotypic ratio of the offspring obtained from the test cross will be: - 1 Rr : 1 rr This means that there is a 50% chance for each genotype, resulting in a genotypic ratio of 1:1 for Rr (pink) and rr (white). This comprehensive analysis illustrates the principles of inheritance and the effects of dominant and recessive alleles on phenotypic expression.
