Multiple choice

The rats espousing to swim near the edge of a water maze is a typical example of

  1. Gravitaxis

  2. Thigmotaxis

  3. Thermotaxis

  4. Rheotaxis

  5. Phonotaxis
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Thigmotaxis is the movement of an organism either towards or away from the stimulus of physical contact or to the proximity of a physical discontinuity in the environment.the most prominent example can be observed in rats espousing to swim near the edge of a water maze).

Multiple choice

What is the muscular tube that starts from the mouth and ends at the anus called?

  1. Digestive gland

  2. Alimentary canal

  3. Oesophagus

  4. Molars

  5. Vermiform appendix
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Alimentary canal, also called digestive tract, is the pathway by which food enters the body and solid wastes are expelled. The alimentary canal includes the mouth, pharynx, oesophagus, stomach, small intestine, large intestine and anus.

  2. Young one is protected inside an egg shell.

  3. Fetus is well protected.

  4. The fetus remains in the womb till the end of the gestation period.

  5. Child birth occurs at the end of gestation period.

B Correct answer
Explanation

The egg shell is seen in the case of oviparous animals, which lay eggs. As the egg comes through the oviduct, it is covered by a shell made of calcium carbonate. The young one hatches out of the incubated egg. The egg shell is absent in viviparous animals.

Multiple choice

What is meant by the term 'incubation'?

  1. Birds sitting on the eggs so as to make them hatch

  2. The mechanism of hearing

  3. The process of egg forming inside the mother bird

  4. Giving birth to live young ones
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Birds sitting on the eggs so as to make them hatch is called incubation.

Multiple choice

The fluid absorbing substance of the cartilage is

  1. chitin

  2. chondroitin

  3. kinin

  4. keratin

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Chondroitin is a molecule that occurs naturally in the body. It is a major component of cartilage. Chondroitin helps to keep cartilage healthy by absorbing fluid particularly water into the connective tissue. It may also block enzymes that break down cartilage, and it provides the building blocks for the body to produce new cartilage.

Multiple choice

The opening of truncus arterisus in frog is guarded by

  1. three semilunar valves

  2. two semilunar valves

  3. one semilunar valve

  4. four semilunar valves

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The truncus arteriosus in frogs is guarded by three semilunar valves that prevent backflow of blood into the ventricle during ventricular relaxation. These valves are similar to the semilunar valves (aortic and pulmonary) in the human heart and ensure unidirectional blood flow from the single ventricle to the arterial system.

Multiple choice

A lymph node is regarded as a part of

  1. circulatory system

  2. digestive system

  3. endocrine system

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

Lymph nodes are integral components of the circulatory system, specifically the lymphatic circulation which is a subset of the broader circulatory system. They filter lymph as it returns to the bloodstream, and the lymphatic vessels ultimately drain into the subclavian veins, connecting directly to blood circulation.

Multiple choice

Foramen of Panizzae is present in the heart of lizards in between

  1. pulmonary arch and systemic arch

  2. two systemic arches

  3. two auricles

  4. left auricle and ventricle
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Foramen of Panizza is a unique anatomical feature in reptiles like lizards, connecting the left and right systemic arches. This allows blood to bypass the lungs when diving, adapting to their ectothermic metabolism.
