Biology Test 3
The pitcher plant is characterized by which of the following plants ?
  • Autotrophes
  • Insectivorous
  • Allergen
  • None of the above
Explanation:

The pitcher plant is an insectivorous plant, meaning it derives some or most of its nutrients from trapping and consuming insects.

It has modified leaves known as pitfall traps—a deep cavity filled with digestive liquid.

This adaptation helps the plant survive in nutrient-poor soils by obtaining essential nutrients from prey.

Which among the following have been found to produce a protein called Defensin-1, which has been found potential to develop drugs for antibiotic resistant bacteria?
  • Codfish
  • Cuttle Fish
  • Honey bee
  • Domestic Fly
Explanation: Honey bees have been found to produce a protein called Defensin-1, which has potential for developing drugs to combat antibiotic-resistant bacteria. Defensin-1 is part of the honey bee's immune response and exhibits strong antimicrobial properties.
Lepidopterology is a branch of biology, which deals with the studies of which of the following?
  • Lipids and fats
  • Butterflies and moths
  • Tongue
  • Lakes and Ponds
Explanation: Lepidopterology is the branch of biology that deals with the study of butterflies and moths. It involves the classification, life cycle, behavior, ecology, and conservation of these insects
The study of Plants Tissues is called__?
  • histology
  • cytology
  • mycology
  • myrmecology
Explanation: Histology, the study of plant tissues, involves analyzing their microscopic structure and function. It includes examining various tissue types, such as vascular, epidermal, and ground tissues, to understand plant growth, development, and physiological processes. Histologists use techniques like staining and microscopy to observe cells and tissues, aiding in research and agricultural advancements.
Which of the following belongs to the Order Pinnipedia?
  • whale
  • cow
  • mole
  • sea lion
Explanation: Sea lions belong to the Order Pinnipedia, which also includes seals and walruses. This order is characterized by their fin-like limbs and adaptations for aquatic life.
Which of the following forms the boundary between the middle and inner ear?
  • incus
  • oval window
  • pinnae
  • tympanic membrane
Explanation: The oval window forms the boundary between the middle ear and the inner ear. It is a membrane-covered opening that the stapes bone (one of the middle ear ossicles) connects to, transmitting vibrations from the middle ear into the fluid-filled inner ear.
Which nerves send messages from all the senses to the brain?
  • Motor nerves
    • Explanation: Sensory nerves are responsible for sending messages from all the senses to the brain. These nerves carry information about touch, temperature, pain, and other sensory stimuli from various parts of the body to the central nervous system.
