Questions Related to animal diversity - ii (phylum: chordata)

Ureotelic vertebrates are?

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

  1. Fish

  2. Reptiles and cartilaginous fish

  3. Bony fish and mammals

  4. Amphibians; mammals, cartilaginous fish

Show answer
Correct Option: D
Explanation:

The excretion of urea is called ureotelism. Land animals, mainly amphibians mammals, convert ammonia into urea. These animals are called ureotelic. Urea is a less toxic compound than ammonia. Eg marine fishes, many amphibians etc.


So the correct option is "amphibian, mammals, cartilaginous fish".

  3. Vestigeal structures

  4. All

Show answer
Correct Option: C
Explanation:

Nictitating membrane (Third eyelid or Plica semilunaris). It is thin, transparent and freely movable fold which is used to clean cornea in frog, pigeon, apes etc.

  1. faecal matter

  2. urine

  3. sperms

  4. all of these

Show answer
Correct Option: D
Explanation:

The cloaca is a small, median chamber that is used to pass faecal matter, urine and sperms. So, the correct answer is (d).

In a uriniferous tubule, what is the short and tubular region, that follows the Bowman's capsule known as?

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

  1. Neck

  2. Proximal convoluted tubule

  3. Henle's loop

  4. Distal convoluted tubule

Show answer
Correct Option: C
Explanation:

In a uriniferous tubule, 'Henle's loop' is the short and tubular region, that follows the Bowman's capsule.

So, the correct option is 'Henle's loop'.

Fill up the blanks in the following paragraph by selecting the correct option.
The vascular system of frog is well-developed ______ (i) type. The blood vascular system involves heart, blood vessels and blood. Heart has 3 chambers, two atria and one ventricle and is covered by a membrane called ______ (ii). A triangular structure called ______ (iii) joins the right attrium.

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

  1. (i)- open; (ii)- conus arteriosus; (iii)- neurilemma

  2. (i)- closed; (ii)- sinus venosus; (iii)- pericardium

  3. (i)- open; (ii)- neurilemma; (iii)- conus arteriosus

  4. (i)- closed ; (ii)- pericardium; (iii)- sinus venosus

Show answer
Correct Option: D
Explanation:

The vascular system of frog is well-developed (i) 'closed' type. The blood vascular system involves the heart, blood vessels and blood. The heart has 3 chambers, two atria and one ventricle and is covered by a membrane called (ii) 'pericardium'. A triangular structure called (iii) 'sinus venosus' joins the right atrium.

So, the correct answer is '(i)- closed ; (ii)- pericardium; (iii)- sinus venosus'.
