Level 2 Animal Care: Biology Revision MCQ's

Which of the following is NOT a function of blood in mammals?

• Transporting oxygen

• Regulating body temperature

• Producing antibodies

• Digesting food

Answer explanation

Blood functions include transporting oxygen, regulating body temperature, and producing antibodies. However, digesting food is not a function of blood; digestion occurs in the digestive system.

What is the normal body temperature range for most mammals?

• 35-37°C

• 37-39°C

• 39-41°C

• 41-43°C

Answer explanation

The normal body temperature range for most mammals is typically between 37-39°C. This range is crucial for maintaining metabolic processes and overall health.

Which digestive system structure allows ruminants like cows to extract more nutrients from plant material?

• Large intestine

• Stomach

• Rumen

• Cecum

Answer explanation

The rumen is a specialized stomach chamber in ruminants like cows that allows for fermentation and breakdown of plant material, enabling them to extract more nutrients compared to other digestive structures.

What is the purpose of rumination in animals like cows and sheep?

• To produce milk

• To regurgitate and rechew food

• To eliminate waste

• To regulate body temperature

Answer explanation

The purpose of rumination in animals like cows and sheep is to regurgitate and rechew food. This process aids in digestion by breaking down food further, allowing for better nutrient absorption.

Which of the following is a sign that a bird may be egg-bound?

• Excessive preening

• Lethargy and straining

• Increased appetite

• Frequent flying

Answer explanation

Lethargy and straining are key signs of a bird being egg-bound, indicating distress and difficulty in laying eggs. Excessive preening, increased appetite, and frequent flying are not typical indicators of this condition.

What is the function of the swim bladder in fish?

• Breathing oxygen from the water

• Controlling buoyancy

• Detecting vibrations in the water

• Filtering out waste products

Answer explanation

The swim bladder in fish primarily functions to control buoyancy, allowing them to maintain their position in the water column without expending energy. This is essential for their movement and stability in aquatic environments.

Which of the following helps reptiles regulate their body temperature?

• Sweating

• Panting

• Basking in sunlight

• Shivering

Answer explanation

Reptiles are ectothermic and rely on external heat sources to regulate their body temperature. Basking in sunlight allows them to absorb heat, which is essential for their metabolic processes.

What is the purpose of the lateral line in fish?

• Breathing

• Detecting electrical signals

• Sensing water movement and vibrations

• Controlling fin movement

Answer explanation

The lateral line in fish is primarily used for sensing water movement and vibrations, allowing them to detect changes in their environment, which is crucial for navigation and hunting.

Which nutrient deficiency can lead to metabolic bone disease in reptiles?

• Protein

• Vitamin C

• Calcium

• Iron

Answer explanation

Calcium deficiency is a primary cause of metabolic bone disease in reptiles, leading to weakened bones and deformities. Unlike protein, vitamin C, or iron, calcium is crucial for maintaining bone health.

What is the main function of feathers in birds?

• Insulation

• Flight

• Display

• All of the above

Answer explanation

Feathers serve multiple functions in birds: they provide insulation to maintain body temperature, enable flight through their aerodynamic structure, and are used for display during mating rituals. Thus, the correct answer is 'All of the above'.
