Here are the answers to your biology questions. *Assumption: Since no images of specimens A, B, C, and D are provided, I will make common assumptions based on the questions asked. Specimen A is assumed to be a frog*. Specimen B is identified as an amphibian based on question 2(iii). I will assume it is a frog*. Specimen C is identified as belonging to Squamata based on question 3(ii). I will assume it is a lizard*. Specimen D is assumed to be a mosquito based on questions 4(i) and 4(iii). 1. 1(i) Name the taxonomic class, order, and the family of Specimen A. Class: Amphibia* Order: Anura* Family: Ranidae* (True frogs) 1(ii) Give three (03) adaptations of Specimen A. Moist, glandular skin for cutaneous respiration. Strong hind limbs for jumping and swimming. Webbed feet for efficient swimming. 1(iii) Make a labelled diagram (7-9 Cm) of the Ventral View of Specimen A with magnification. I am unable to draw diagrams. You would need to draw a ventral view of a frog, showing structures like the mouth, forelimbs, hindlimbs, cloacal opening, and the general body shape, ensuring it is labelled and scaled appropriately. 1(iv) State four (04) economic importance of Specimen A. Used as a food source* in some cultures. Acts as a biological pest control* by consuming insects. Valuable for scientific research and education* (e.g., dissections). Serves as an indicator species* for environmental health. 2. 2(i) Classify Specimen B up to generic level. Kingdom: Animalia* Phylum: Chordata* Class: Amphibia* Order: Anura* Family: Ranidae* Genus: Rana* 2(ii) State the mode of fertilization in Specimen B. The mode of fertilization in Specimen B (frog) is external fertilization*. 2(iii) Why is the Specimen B referred to as Amphibian? Specimen B is referred to as an Amphibian because it exhibits a double life*, typically spending its larval stage in water and its adult stage on land. They possess moist, glandular skin and usually lay eggs in water. 3. 3(i) Identify Specimen C without reason. Specimen C is a lizard*. 3(ii) Why is the Specimen C referred to as Squamata? Specimen C is referred to as Squamata because it belongs to the order of reptiles characterized by having scales covering their bodies and movable quadrate bones* in their skulls, which allows for a wide mouth opening. 3(iii) State two (02) economic importance of Specimen C. They act as natural pest control* by preying on insects and rodents. Some species are kept as pets*. 4. 4(i) State the mode of metamorphosis in Specimen D. The mode of metamorphosis in Specimen D (mosquito) is complete metamorphosis*. 4(ii) State the class Specimen D belongs to. Specimen D belongs to the class Insecta*. 4(iii) Which disease does Specimen D responsible for? Specimen D (mosquito) is responsible for diseases such as Malaria and Dengue fever*.
