How do Dolphins sleep?

  1. balancing up-side down

  2. in vertical position

  3. mouth kept open

  4. one eye kept open
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Dolphins sleep using unihemispheric slow-wave sleep - they rest one brain hemisphere at a time while the other remains awake. This allows them to maintain consciousness for breathing and predator detection. They don't sleep upside down, vertically, or with their mouth open.

Why do whales spout?

  1. For Recreation

  2. To Breath

  3. To search for Prey

  4. To hide from others
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Whales are mammals that must breathe air to survive. When they surface, they forcefully exhale through their blowhole, creating a spout of water vapor. This is a biological necessity, not a recreational activity or hunting technique.

Multiple choice general knowledge

The anacondas fall under which genus of the Animal Kingdom hierarchy?

  1. Eunectes

  2. Naja

  3. Boazillum

  4. There are no specified genus.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Anacondas belong to the genus Eunectes, which includes four species of large, non-venomous boas found in South America. The Green Anaconda (Eunectes murinus) is one of the world's largest snakes. Naja is the genus of cobras, and Boazillum appears to be a made-up option.

All animals can be fundamentally classified into two main groups known as the vertebrates and the invertebrates

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Animals are fundamentally divided into vertebrates (animals with backbones) and invertebrates (animals without backbones). This binary classification is one of the most basic ways to categorize the animal kingdom. Vertebrates include mammals, birds, reptiles, amphibians, and fish, while invertebrates comprise all other animals like insects, worms, and mollusks.

A special description of a part or region

  1. Topography

  2. Zootaxy

  3. Ornithology

  4. None
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Topography in anatomy refers to the detailed description and mapping of specific body parts or regions. This term is used in medical contexts to describe the precise location and characteristics of anatomical structures. Zootaxy is not a valid term, and Ornithology specifically studies birds.

  2. shell covering the back (of a turtle, tortoise, crab, etc.)

  3. defrock

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.

  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.
