Identify the parasites in A and B and suggest two biological control measures for the parasite in B. Then, identify the diseases affecting Animal 1 and Animal 2.

You're on a roll — 3.6.1 The parasite in B is a trematode (or flatworm). This is indicated by its complex life cycle involving a snail as an intermediate host and a sheep as the definitive host, characteristic of a liver fluke. The classification is: Trematode 3.6.2 A: The life cycle in A, involving a human and a cow, with larvae in meat, represents a tapeworm (specifically, Taenia saginata* or beef tapeworm). B: The life cycle in B, involving a sheep and a snail, represents a liver fluke (e.g., Fasciola hepatica*). The parasites are: A: Tapeworm B: Liver fluke 3.6.3 Two biological measures that can be used to control the parasite in B (liver fluke) are: Introducing natural predators* of snails (e.g., ducks) into affected areas. Introducing competitor snail species* that do not serve as intermediate hosts for the liver fluke. 3.7.1 Animal 1: The symptoms of bleeding from the mouth, nose, and anus are characteristic of Anthrax*. Animal 2: The symptoms of dark red urine, pale eyes, and anaemia are characteristic of Redwater fever* (also known as Bovine babesiosis). The diseases are: Animal 1: Anthrax Animal 2: Redwater fever 3.7.2 Anthrax is a deadly bacterial disease. Animal 1 is suffering from Anthrax. The animal is: Animal 1 3.7.3 Based on the information provided: Animal 1 has Anthrax, which is an infectious bacterial disease*. Animal 2 has Redwater fever, which is an infectious parasitic disease*. Therefore, neither animal is indicated to have a non-infectious disease based on the primary diseases described. The answer is: Neither 3.7.4 The disease in Animal 2 is Redwater fever, which is caused by Babesia parasites. These parasites are transmitted by ticks. The specific vector is: Tick What's next? 📸
