  3. Foot and Mouth

  4. Pebrine

  1. Liver

  2. Gall bladder

  3. Pancreas

  4. Spleen

  1. pericardium

  2. pleural membrane

  3. peritoneal membrane

  4. meninx

Multiple choice

Which of the following statements about nutrition in amoeba is/are incorrect?

a. The enzymes present in vacuole break down the food. b. The food becomes soluble inside the cytoplasm in amoeba. c. The cytoplasm disappears after absorption of food.

  1. only a

  2. only b

  3. only c

  4. only a and c

  5. a, b and c
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

This is the correct answer as all the statements are incorrect. 

Digestive enzymes present in the cytoplasm enter the food vacuole to break the food down. The digestion takes place inside the food vacuole due to which the food becomes soluble. The food vacuole disappears after the absorption of food in amoeba.

Multiple choice

Patagium is an organ in flying mammals which is synonymous to

  1. flippers

  2. parachute

  3. wings

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

The patagium in flying mammals like bats functions as a parachute-like membrane that provides lift and drag during gliding and flight. Unlike wings (which have rigid structures) or flippers, the patagium is a flexible skin membrane that creates resistance against air, similar to parachute mechanics.

Multiple choice

Prominent oral structures are derived from

  1. pharynx

  2. larynx

  3. gill pouch

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

During embryonic development, prominent oral structures including parts of the mouth, palate, and certain throat structures derive from the gill pouches (pharyngeal pouches). These are evolutionary remnants in vertebrate development. The pharynx, larynx, and gill pouches are related embryological regions.

Multiple choice

Epiglottis is a part of

  1. pharynx

  2. larynx

  3. glottis

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

The epiglottis is indeed part of the larynx (voice box). It's a leaf-shaped cartilage that projects upward behind the tongue and protects the trachea during swallowing. The pharynx is the throat region, and the glottis is the actual opening into the larynx - the epiglottis guards this opening.
