(a) State four effects of specimen E on farm animals
(b) Name the primary and intermediate host of specimen E,
(c) State three adaptive features of specimen F which enable it to survive in Its host
(d) State three control measures of each of specimens E and F in livestock management

Answer Details

(a) Four effects of specimen E on farm animals include:

1. Reduced feed intake: Specimen E can cause a decrease in appetite and feed intake in infected animals, which can lead to weight loss and decreased productivity.
2. Anemia: Infected animals may develop anemia due to the destruction of red blood cells by the parasite.
3. Weakness and lethargy: Infected animals may become weak and lethargic, which can also impact their productivity.
4. Death: In severe cases, specimen E can cause death in infected animals.

(b) The primary host of specimen E is the tsetse fly, and the intermediate host is the bloodstream of the infected animal.

(c) Three adaptive features of specimen F that enable it to survive in its host include:

1. Ability to evade the immune system: Specimen F is able to evade the immune system of its host, allowing it to avoid detection and continue to thrive.
2. High reproductive rate: Specimen F is able to reproduce quickly within its host, allowing it to establish a large population and compete with other microorganisms for resources.
3. Ability to adapt to changing environments: Specimen F is able to adapt to changing conditions within its host, allowing it to survive in a range of different environments.

(d) Three control measures of specimen E in livestock management include:

1. Use of insecticides: Tsetse flies can be controlled using insecticides, which can reduce the number of infected animals.
2. Improved management practices: Improved management practices such as regular veterinary care, nutrition, and sanitation can help to reduce the impact of specimen E on livestock.
3. Use of resistant breeds: Some breeds of livestock are resistant to the effects of specimen E and can be used to reduce the impact of the parasite on livestock populations.

Three control measures of specimen F in livestock management include:

1. Use of antibiotics: Specimen F can be controlled using antibiotics, which can kill the microorganisms and reduce their impact on the host.
2. Improved hygiene and sanitation: Improved hygiene and sanitation practices can help to reduce the spread of specimen F and other microorganisms in livestock populations.
3. Use of vaccines: Vaccines can be used to protect livestock against specimen F and other microorganisms, reducing the impact of these parasites on livestock populations.
