Section A - Very Short Answer Type Questions (2 Marks Each)
| Question | AP Inter 1st Year Zoology Answer Key 2025 |
| 1. Define species richness. | Species richness refers to the number of different species present in a particular ecosystem, community, or geographic area. It is a measure of biodiversity that takes into account the variety of species, without considering their relative abundance or distribution. |
| 2. What is the Haematocrit Value? | The Haematocrit (Hct) value represents the proportion of red blood cells in the total blood volume, expressed as a percentage. It signifies the ratio of red blood cell volume to total blood volume. Normally, the Haematocrit value ranges from 40-54% in males and 37-48% in females. |
| 3. Mention any two substances secreted by mast cells and their functions. |
Two substances secreted by mast cells are:
a. Histamine: It causes blood vessels to dilate, leading to increased permeability and smooth muscle contraction, resulting in allergic symptoms such as itching, swelling, and increased mucus production. b. Heparin: It acts as an anticoagulant, preventing blood clotting and promoting blood flow, which helps to prevent excessive clotting during inflammation. |
| 4. Mention the animals that exhibited a "tube-within-a-tube" organisation for the first time. Name their body cavity. | The animals that exhibited a "tube-within-a-tube" organization for the first time are Annelids (segmented worms), such as earthworms. Their body cavity is called a "true coelom" or "schizocoelom". |
| 5. What is botryoidal tissue? | Botryoidal tissue refers to a type of tissue that resembles a cluster of grapes. It is characteristic of the placenta in mammals, particularly in the early stages of development. |
| 6. What are 'Jacobson's organs? What is their function? | Jacobson's organs, also known as vomeronasal organs (VNOs), are specialized sensory organs found in many animals, including mammals, reptiles, and amphibians. Their function is to detect pheromones, which are chemical signals that convey information about reproductive status, dominance, and other social behaviors. |
| 7. What is kinety? | Kinety refers to a group of cilia (hair-like structures) that beat in a coordinated manner to create a current or movement in a specific direction, typically found in ciliates and other protists. |

| 9. What do you mean by parasitic castration? Give one example. | Parasitic castration refers to the phenomenon where a parasite infects a host organism and manipulates its reproductive system, leading to the suppression or elimination of the host's reproductive capabilities. Example: The parasitic crustacean Sacculina infects crabs and manipulates their reproductive system, rendering them sterile and unable to reproduce. |
| 10. Define Commensalism. Give one example. | Commensalism is a type of symbiotic relationship where one organism, the commensal, benefits from the association, while the other organism, the host, is neither harmed nor benefited. Example: Remora fish (suckerfish) attach themselves to the bodies of sharks and feed on their leftover food particles, providing no benefit or harm to the shark. |
