Animal Tissue and Anatomy Questions

Multiple choice zoology gas exchange in humans human respiration the mechanism of breathing breathing and its movements

Choose the correct answer from the alternatives given.
In which of the following structures vocal cords are located?

  1. Oesophagus

  2. Larynx

  3. Pharynx

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

The vocal cords are folds of membranous tissue that are located within the larynx at the top of the trachea. Their edges vibrate in an airstream to produce voice. So, the correct option is 'Larynx'.

Multiple choice zoology gas exchange in humans human respiration the mechanism of breathing breathing and its movements

Choose the correct answer from the alternatives given.
The Adams apple is formed predominantly, by which of the following structures?

  1. Larynx

  2. Pharynx

  3. Oesophagus

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

The Adam's apple is a laryngeal protrusion that is formed by the angle of the thyroid cartilage surrounding the larynx and is seen especially in males. So, the correct option is 'larynx'.

Multiple choice biology breath and blood of life human respiration the mechanism of breathing breathing and its movements

Choose the correct answer from the alternatives given.
The respiratory medium flows unidirectionally ever the respiratory surface in the gas-exchange systems of:

  1. mammals

  2. frogs

  3. birds

  4. insects
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In birds, the air sacs permit unidirectional flow of air through the lungs. Unidirectional flow means that air moving through bird lungs is largely 'fresh' air & has a higher oxygen content. So, the correct option is 'birds'.

Multiple choice evs structure and functions of living organisms -ii experiments on digestive enzymes role of receptors in the mouth types of teeth introduction to human digestive system circulatory system and organs

Nasal chamber is divided in tow parts by?

  1. Sphenoid bone

  2. Palatine bone

  3. Mesethemoid cartilage

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

The nasal cavity is divided into two lateral halves by the nasal septum, which is formed by the vomer, the perpendicular plate of the ethmoid bone, and the septal cartilage.

Among mammals, an herbivore has

  1. More teeth than carnivore

  2. Flatter teeth than carnivore

  3. Teeth that are more pointed than carnivore

  4. Fever teeth than a carnivore
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The teeth of a carnivore are long and pointed, for tearing raw flesh. Herbivores have flat teeth and flat back molars to grind their food. Carnivores do not have flat back molars at all.  Some herbivores do have small, what we call “canine” teeth for biting into tough plants like apples but these are nothing compared to the size and shape of a carnivore’s teeth. True omnivores teeth are most similar to carnivore teeth. Thus, option B is correct. 

Multiple choice biology the age of adolescence menstruation in females changes at puberty what happens if an egg is not fertilized?

Sexual dimorphism is the 

  1. Genotypic difference

  2. Phenotypic difference

  3. Neurological difference

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Sexual dimorphism refers to the condition where the two sexes of the same species show different characteristics apart from the differences in their sex organs.
  • As both sexes consist of different chromosome pattern ( for e.g. XX AND XY in human beings), they differ genotypically.
  • Those observable characters which are visible to us and helps us in knowing the sex of any animal/plant without knowing their chromosome pattern are essentially what phenotypic difference is about.
  • So, the correct answer is 'Both A and B'.
Multiple choice biology our skeletal system and the skin bones and movements joints in the human body joints

Tuberculum and capitulum are related to

  1. Skull

  2. Pelvic girdle

  3. Ribs

  4. Neural arches
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

At the spinal column, the rib starts with the rib head (caput costae or capitulum). The rib bone progresses backwards via the rib neck (collum costae) to the rib tubercle (tuberculum costae). This is where the rib body (corpus costae) begins, which curves round to the front with the rib angle (angulus costae).

Feeding jaggery along with lime water is one of the first aid measure for

  1. Diarrhoea

  2. Constipation

  3. Milk fever

  4. Anthrax
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Milk fever is a disorder of mainly dairy cows close to calving.
  • It is a metabolic disease caused by a low blood calcium level. Feeding jaggery along with lime water, a few days prior to calving and giving soft nutritious and easily digestible food for few days after calving prevent milk fever.
Thus, the correct answer is option C.
