Diversity in Living Organisms

3,323 Questions

The diversity in living organisms deals with the classification of life forms into various kingdoms and phyla. This topic covers specific traits of bacteria, animal body cavities, and structural adaptations for survival. These fundamentals are crucial for biology sections in medical entrance and state board exams.

Researchers at Cornell University have demonstrated that homing pigeons can sense changes in the earth's magnetic field, see light waves that people cannot see, detect low-frequency sounds from miles away, sense changes in air pressure, and can identify familiar odors.

  1. A. sense changes in air pressure, and can identify familiar odors

  2. B. can sense changes in air pressure, and can identify familiar odors

  3. C. sense changes in air pressure, and identify familiar odors

  4. D. air pressure changes can be sensed, and familiar odors identified

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This is a sentence correction/redundancy elimination question. The original sentence lists capabilities redundantly with 'can' appearing multiple times. Option C 'sense changes in air pressure, and identify familiar odors' maintains parallel structure without the redundant 'can' while preserving meaning.

  1. A. sense changes in air pressure, and can identify familiar odors

  3. C. sense changes in air pressure, and identify familiar odors

  4. D. air pressure changes can be sensed, and familiar odors identified

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The question asks for a grammatically correct and parallel construction. The original sentence uses 'can sense' and 'can identify' - repeating 'can' is unnecessary and disrupts parallel structure. Option C correctly places both verbs in their base form ('sense' and 'identify') after the implied 'can', creating proper parallel structure: 'can sense changes...and identify familiar odors.' The other options either maintain the unnecessary repetition of 'can' or use awkward passive voice constructions.
