Diversity in Living Organisms

3,829 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.

B Correct answer
Explanation

Yes, it is correct. Viruses reproduce only inside the cells of the host organism, which may be a bacterium, plant or animal.

  2. multicellular

  3. cell clusters

  4. unicellular or multicellular

  5. unicellular, multicellular or cell clusters

E Correct answer
Explanation

Yes, it is the correct answer. Microorganisms can exist as unicellular, multicellular or cell clusters.

Multiple choice

All Rattlesnakes belong to the Viperidae family strikes when special heat sensing pits on its face sense a prey, after biting its prey, follows its body heat to locate it.

  1. belong to the Viperidae family strikes when special heat sensing pits on its face sense a prey, after biting its prey, follows its body heat to locate it

  2. belonging to the Viperidae family strike when special heat sensing pits on their face senses a prey; after biting their prey, follow the body heat of the bitten prey to locate it

  3. which belong to the Viperidae family strike when special heat sensing pits on their face sense a prey; after biting their prey, follow its body heat to locate it

  4. belong to the Viperidae family and strike when special heat sensing pits on their faces sense a prey, and after biting their prey, follow the body heat of the bitten prey to locate it

  5. belong to the Viperidae family; they strike when special heat sensing pits on their face sense a prey, and after biting their prey, follow the body heat of the bitten prey to locate it
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Correct answer; removes the subject verb errors of referring to the singular 'family' rather than the plural 'rattlesnakes' as the subject of the sentence; removes the ambiguity about whether rattlesnakes follow their own body heat or the prey's body heat.

Multiple choice

A careful perusal of the history of the evolution of whales reveals that they were not always complete sea dwellers but evolved slowly from amphibian ancestors.

  1. reveals that they were not always complete sea dwellers but evolved slowly

  2. reveals that the whales were not always complete sea dwellers but evolved slowly

  3. reveals that the whales had not always been complete sea dwellers but evolved slowly

  4. reveals that the whales had not always been complete sea dwellers but had evolved slowly

  5. revealed that they had not always been complete sea dwellers but evolved slowly
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Correct. The option removes the error of missing antecedent by using 'whales' instead of 'they'. Also, the option removes the error of Tense Usage by using Past Perfect to report an event (whales being amphibians/ were not complete sea dwellers) that took place before the evolution of whales into sea mammals.

Multiple choice

The planktonic larvae of the king crab (Lithodes aequispinus) use which of the following types of nastic movement while swimming upwards?

  1. Thigmotaxis

  2. Thermotaxis

  3. Rheotaxis

  4. Gravitaxis

  5. Phonotaxis
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Gravitaxis is a response to the attraction due to gravity. The planktonic larvae of the king crab (Lithodes aequispinus) use a combination of positive phototaxis (movement towards the light) and negative gravitaxis (upward movement).

Multiple choice

Why is the shape of birds streamlined?

  1. To minimize force of friction

  2. To increase force of friction

  3. To overcome gravitational force

  4. To protect themselves from the ill effects of sunlight
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Birds evolved streamlined bodies to minimize air resistance (friction) during flight, making movement more efficient. Increasing friction would make flight harder, while body shape is unrelated to overcoming gravity or protection from sunlight.
