Who proved that blends of polyblend (plastic waste) and bitumen, when used to lay roads, enhanced the bitumen's water repellent properties and helped to increase road life?

zoology garbage in, garbage out plastic waste thermocol ways to reduce non degradable garbage recycling of paper

  1. Amrita Devi

  2. Ramdeo Misra

  3. WH Pearsall

  4. Ahmed Khan

  5. Ramesh Chander Dagar

Show answer
Correct Option: D
Explanation:

K. Ahmed Khan is an Indian scientist and businessman who made success in using plastic for road construction. He is the founder of KK Plastic Waste Management Pvt.Ltd.He along with his brother Rasool Khan, stung by protests to ban plastic, hit upon the idea of recycling plastic and mixing it with bitumen to lay roads. Ahmed Khan proved that blends of Polyblend and Bitumen, when used to lay roads enhanced the bitumen's water repellant properties and helped to increase road life by a factor of three.

So the correct answer is 'Ahmed Khan'.

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

zoology skeleton and movements introduction to movement introduction to locomotion movement

  1. Leeuwenhoek

  2. Aristotle

  3. Socrates

  4. Swaminathan

Show answer
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

Show answer
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?

zoology skeleton and movements introduction to movement introduction to locomotion movement

  1. Duodenal muscles

  2. Pharyngeal muscles

  3. Skeletal muscles

  4. Lip muscles

Show answer
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.

Show answer
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

zoology skeleton and movements introduction to movement introduction to locomotion movement

  1. Single cell

  2. Single-celled organism

  3. Cell organelles

  4. All the above

Show answer
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. 

Which of the following features is common to all animals without any exception?

zoology skeleton and joints introduction to movement introduction to locomotion movement

  1. Locomotion

  2. Specialised nervous system

  3. Multicellularity

  4. Herbivorous mode of nutrition

Show answer
Correct Option: A
Explanation:
  • Locomotion is the active movement i.e. with consumption of energy shown by all organism. Need, type and extent of locomotion differ from organisms to organism based on their organisation. 
  • The specialised nervous system is seen in only organisms with organ system level of organisation. 
  • Several organisms are unicellular, hence multicellularity is not a common feature of all organisms. 
  • All organisms differ in their mode of nutrition. They can be autotrophic or heterotrophic. If heterotrophic, they can be herbivores, carnivores or omnivores.
  • So, the correct option is 'Locomotion'.

How many muscles are used in the movement of a bone?

  1. 1

  2. 2

  3. 3

  4. 4

Show answer
Correct Option: B

The movement and locomotion of all animals is exactly the same.

zoology skeleton and joints introduction to movement introduction to locomotion movement

  1. True

  2. False

Show answer
Correct Option: B
Explanation:
Animals exhibit a wide range of movements. The voluntary movements that result in a change of place or location are called locomotion. There are three main types of movements, namely, amoeboid, ciliary and muscular.
Streaming of protoplasm in the unicellular organisms like Amoeba is a simple form of movement. In Paramoecium, cilia help in the movement of food and in locomotion as well. In Paramoecium, cilia help in the movement of food and in locomotion as well. Birds fly, fish swim and humans use limbs for changes in body postures and locomotion as well. Hence, the answer is false.
