Who is the author of the book 'Gait of animals'?

  1. Leeuwenhoek

  2. Aristotle

  3. Socrates

  4. Swaminathan


Correct Option: B
Explanation:

The author of the book 'Gait of animals' is Aristotle. It was written in 350 BC.
This book consists of information about the movement of animals. Gait is the pattern of movement of the limbs of animals, during locomotion over a solid substrate. Most animals use a variety of gaits, selecting gait based on speed, terrain, the need to maneuver, and energetic efficiency. Aristotle was an ancient Greek philosopher and scientist born in the city of Stagira, Chalkidiki, in the north of Greece. He was a student of Plato and considered as an important figure in western philosophy.

  • So, the correct option is 'Aristotle'.

Read the following statements and select the correct 
Statement 1 : Locomotion is the movement of an individual from one place to another. 
Statement 2 : All movements are locomotions buts all locomotions are not movement.

  1. Both statements 1 and 2 are correct

  2. Statement 1 is correct but statement 2 is correct

  3. Statement 1 is Incorrect but statement 2 is correct

  4. Both statements 1 and 2 are incorrect


Correct Option: A
Explanation:

Both the statements are true.

So, the correct option is 'Both statements 1 and 2 are correct'.

Which of the following muscles are not able to contract voluntarily?

  1. Duodenal muscles

  2. Pharyngeal muscles

  3. Skeletal muscles

  4. Lip muscles


Correct Option: A
Explanation:

Muscles which are able to contract voluntarily are only skeletal muscles.

A) Duodenal muscles are not skeletal but smooth muscles and are therefore not able to contract voluntarily.
B) Pharangeal muscles are skeletal muscles and are hence able to contract voluntarily.
C) Skeletal muscles are under voluntary control and can be contracted voluntarily.
D) Lip muscles are skeletal muscles and are hence able to contract voluntarily.
So, the answer is 'duodenal muscles'.

Which of the following statements is not true ?

  1. The cartilage is not as hard as bones.

  2. A snake moves by making loops.

  3. All animals show exactly similar movements.

  4. Snails move with the help of their muscular feet.


Correct Option: C
Explanation:
All animals do not show exactly similar movements.
Animal movements are usually based on their habitat. Different animals have different organs for locomotion. For example, Snakes crawl by forming loops while birds fly with their wings. 

Taxis is movement in

  1. Single cell

  2. Single-celled organism

  3. Cell organelles

  4. All the above


Correct Option: D
Explanation:

Taxis is a kind of behavioural response of a cell, cell organelles or an organism to an external stimulus such as light or food. It is the orientation of an organism or a cell in a specific spatial relationship to a stimuli. If the movement is towards the stimuli it is positive taxis and if it is away from the stimuli it is negative taxis. 

Thus, the correct answer is option D. 

Select the correct option. 

  1. Locomotion is shown by multi cellular organisms

  2. Paramecium uses tentacles for locomotion

  3. Hydra uses cilia for locomotion

  4. Kangroo cannot walk backward


Correct Option: D
Explanation:

  • Locomotion is a feature exhibited by both unicellular and multicellular organisms. 
  • Paramecium uses cilia for its locomotion and Hydra uses somersaulting or gliding movement for its locomotion. 
  • Kangaroos can't walk backward. An unusual feature of the kangaroo is that it cannot walk backwards. This is because of its unusually shaped hind legs and bulky tail which can grow up to four feet long.

So the correct option is 'Kangaroo cannot walk backward'.

What does the word pseuopod mean ?

  1. Hidden arm

  2. False foot

  3. Soft bodied

  4. Multi limbed


Correct Option: A

Which of the following statements is not true?

  1. The cartilage is not as hard as bones.

  2. A snake moves by making loops.

  3. All animals show exactly similar movements.

  4. Snails move with the help of their muscular feet.


Correct Option: C
Explanation:

All animals exhibit different patterns of movements. The movements differ with differences in the types of joints present in the animals. Example: In birds, the forelimbs are modified to result in wings, which leads to flying movement. In case of kangaroos, the hind limbs are modified such that they contain flexible muscles resulting in their jumping movement. In humans, the legs are modified so that they walk with two limbs only, as opposed by other vertebral mammals like dogs, cats etc. which have 4 limbs.

Hence the statement, 'all animals show exactly same movements' is false.

A snail moves with the help of its

  1. Shell

  2. Wings

  3. Bristles

  4. Feet


Correct Option: D
