Multiple choice biology locomotion and movements introduction to locomotion skeleton and joints movement in animals

The purpose of locomotion is to search

  1. Food

  2. Shelter

  3. Mate

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Animals move for a variety of reasons, such as to find food, a mate, a suitable microhabitat, or to escape predators.
  •  For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms. Hence, The purpose of locomotion is to search Food, Shelter and Mate. So,the correct answer is 'All of the above'.

Human body exhibits type of movement is

  1. Amoeboid

  2. Ciliary

  3. Muscular

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Movement is a characteristic feature of living organisms. The different types of movement exhibited by cells of the human body are: 
  • Amoeboid movement: Leucocytes present in the blood show amoeboid movement. 
  • Ciliary movement: Reproductive cells such as sperms and ova show ciliary movement.
  •  Muscular movements:  Muscle tissue found inside of the heart, digestive organs, and blood vessels serve to move substances throughout the body. Hence, The cells of the human body exhibits type of movement are Amoeboid, Ciliary and Muscular.
So, the correct answer is 'All of the above'.

The ability to move from one place to another is called as

  1. Locomotion

  2. Tropic movement

  3. Nastic movement

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

  •  Locomotion is when the movement of a part of the body leads to change in the position and location of the organism. 
  •  In multicellular animals, these movements include walking, running, jumping, crawling, climbing, swimming, flying, galloping, slithering, and so on. Hence, The ability to move from one place to another is called Locomotion.
So, the correct answer is 'Locomotion'.

Which of the following assist locomotion in snake

  1. Scutes

  2. Parapodia

  3. Flagella

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Generally snakes have two kind of scales. Its top and sides are generally covered by smaller scales and The bottom of the snake is covered by short but very wide scales that look like rungs on a ladder.
  • These special scales at the bottom surface are called scutes.They form the belly of the snake and are integral in the snake’s ability to move.
  • Hence scutes assist in locomotion in snake.
  • So,the correct answer is 'Scutes'.

Locomotion is

  1. Voluntary movement

  2. Involuntary movement

  3. Nastic movement

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

  • Locomotion in biology pertains to the various movements of organisms (single-celled or multicellular organisms) to propel themselves from one place to another.

  • In multicellular animals, these movements include walking, running, jumping, crawling, climbing, swimming, flying, galloping, slithering, and so on. Voluntary muscles are the ones that you can control. 

  • Most of them move your bones around. If you want to run, walk, ride a bike, wave your arms around, or eat your favorite sandwich, it is your voluntary muscles by which u move your arms, legs, and body around. Hence, Locomotion is Voluntary movement.
     
So, the correct answer is 'Voluntary movement'.

The smallest muscle in the human body is

  1. Sartorius

  2. Stapedius

  3. Stapes

  4. Mandibular
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Stapedius is a muscle on the wall of the tympanic cavity of the middle ear. It is the smallest skeletal muscle in the human body. It acts reflexively in response to loud sounds by reducing excessive vibrations that may injure the internal ear. Thus the correct answer is option B.

Epicuticle in exoskeleton is made up of

  1. Lipoprotein

  2. Chitin

  3. Polysaccharide

  4. Fructolipase
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The exoskeleton of animals within the phylum Arthropoda mainly consists of a coating called the cuticle.
  •  On the exterior surface of the cuticle is a thin, waxy layer called the epicuticle. 
  • The epicuticle is formed of three layers; the inner layer is the cuticulin, which is made from lipoproteins. Hence, Epicuticle in exoskeleton is made up of Lipoprotein
    • So, the correct answer is 'Lipoprotein'.

Which of the following is not a biological function of skeleton?

  1. Support

  2. Storage

  3. Excretion

  4. Movement
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • The human skeleton is the internal framework of the body.
  •  It is composed of around 270 bones at birth this total decreases to around 206 bones by adulthood after some bones get fused together. 
  • The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulation. Hence, Excretion is not a biological function of the skeleton.
So, the correct answer is 'Excretion'.

Shedding of exoskeleton to replace it due to growth in body is called as

  1. Moulting

  2. Ecdysis

  3. Both A and B

  4. Molding
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • Ecdysis is the moulting of the cuticle in many invertebrates of the clade Ecdysozoa.
  •  Since the cuticle of these animals typically forms a largely inelastic exoskeleton, it is shed during growth and a new, larger covering is formed.
  • The remnants of the old, empty exoskeleton are called exuviae. 
  • In arthropods, such as insects, arachnids and crustaceans, Moulting is the shedding of the exoskeleton (which is often called its shell), typically to let the organism grow. Hence, Shedding of the exoskeleton to replace it due to growth in the body is called ecdysis and moulting. 
So, the correct answer is 'Both A and B'.
