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

Which of the following is the form of locomotion?

  1. Swimming

  2. Opening of stomata

  3. Blooming of flowers

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

Locomotion can be seen in  different media. 
Animals move through, or on, four types of environment: 

  • Aquatic (in or on water), 
  • terrestrial (on the ground or other surfaces, including arboreal, or tree-dwelling),
  •  fossorial (underground), and 
  • aerial (in the air). Hence, Swimming is the form of locomotion.
So, the correct answer is 'Swimming'.

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'.

Multiple choice zoology neural control and coordination structure and function of spinal cord the spinal cord spinal cord

Lining of brain ventricle and central canal of spinal cord is called as

  1. Ependyma

  2. Endothelium

  3. Mesothelium

  4. Neurosensory
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The ciliated cells that line fluid-filled cavities of ventricles of the brain and central canal of the spinal cord are called as ependyma. The endothelium is the inner most layer of arteries and veins. Mesothelium is the epithelial layer of the thoracic and abdominal cavity. The afferent nerves serve the neurosensory function. 
So, the correct answer is option A.

Meninges are the membranes of connective tissue. What is the location of these membranes in the human body?

  1. Brain and spinal cord

  2. Cerebrum

  3. Mid brain

  4. Spinal cord
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The primary function of the meninges and of the cerebrospinal fluid is to protect the central nervous system. Infection of the meninges is called Meningitis. It could be bacterial, Viral, Fungal or Protozoal in origin.

Cavity present in the spinal cord is termed as

  1. Central canal

  2. Fourth ventricle

  3. Volkmanns canal

  4. Iter
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The fourth ventricle present between the brainstem and the cerebellum is called the metacoel. It continues to the spinal cord in the form of the central canal to form the cavity of the spinal cord filled with the cerebrospinal fluid. The central canal is also called the neurocoel.

A. Central canal is the cavity of the spinal cord.
B. The fourth ventricle is present between the brain stem and the cerebellum.
C. Volkmann's canal is present in the long bones.
D. Iter connects the 3rd and the 4th ventricle.
Hence, the correct answer is 'Central canal'
