intestine of frog


  1. Ileum

  2. Jejunum

  3. Duodenum

  4. None of these

The epithelial lining of the alveoli of frog's lungs facing lung
cavity is

  1. Columnar and ciliated

  2. Squamous and ciliated

  3. Squamous and nonciliated

  4. Columnar and nonciliated
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ciliated columnar epithelium comprises columnar cells which have cilia on free surface. This epithelium lines most of the respiratory tract and fallopian tubes.

Multiple choice zoology frog circulatory system in frog frog - digestive system, circulatory system, excretory system and reproductive system animal diversity - ii (phylum: chordata)

A spiral valve present in

  1. Sinus venosus of frog's heart

  2. Right auricle of rabbit's heart

  3. Pylangium of the conus arteriosus of frog's heart

  4. Synangium of the conus arteriosus of frog's heart
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A large twisted spiral valve divides incompletely the cavity of pylangium into a left dorsal cavum  pulmocutaneum and right ventral cavum aorticum.

Multiple choice zoology animal diversity - ii (phylum: chordata) circulatory system in frog frog - digestive system, circulatory system, excretory system and reproductive system frog

Glands of Swammerdam are related with

  1. Spinal nerves of frog

  2. Cranial nerves of frog

  3. Endocrine system of frog

  4. Alimentary canal of frog
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Glands of swammerdam are soft chalky masses of calcareous bodies found in the dorsal root ganglion of spinal nerve in frog. These form reserve supplies of calcium.

Multiple choice zoology frog circulatory system in frog frog - digestive system, circulatory system, excretory system and reproductive system animal diversity - ii (phylum: chordata)

When a frog is transferred from $20^{o}$C to $30^{o}$C, its body temperature ________________.

  1. Falls to $15^{o}$C
  2. Rises to $30^{o}$C
  3. Falls to $12^{o}$C

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

Frogs are ectothermic (poikilothermic) animals, meaning their body temperature fluctuates with the ambient temperature of their environment.

Multiple choice zoology frog circulatory system in frog frog - digestive system, circulatory system, excretory system and reproductive system animal diversity - ii (phylum: chordata)

Three chambered heart of frog is not as efficient as four chambered human heart because _______________.

  1. Heart muscles are not strong

  2. It does not hold enough blood

  3. Ventricle does not pump blood properly

  4. Oxygenated and deoxygenated blood mix up
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Frog has three chambered heart with two atria and one ventricle, the Left atrium receives oxygenated blood from the lungs while the right atrium receives deoxygenated blood from the body. Both the atria empty into single ventricle due to which the blood gets mixed up. So the 'Oxygenated and deoxygenated blood get mixed up'. 
So, the correct answer is 'Oxygenated and deoxygenated blood mix up'
Multiple choice zoology animal diversity - ii (phylum: chordata) circulatory system in frog frog - digestive system, circulatory system, excretory system and reproductive system frog

Velocity of conduction of nerve impulse in frog is ________________.

  1. Faster than sound

  2. 30 metro per second

  3. 300 metro per second

  4. None of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The velocity of nerve impulse conduction in a frog is significantly slower than 30 m/s, typically ranging around 20-30 m/s depending on the nerve fiber type. Since 30 m/s is a specific value but often cited as an approximation, 'None of these' is technically correct if the exact value is not listed.
