Pelvic girdle consists of two coxal bones. Each coxal bone is formed by the fusion of three bones  (i), Ischium, and (ii) . At the point of fusion of the above bones, there is a cavity called (iii) to which the thigh bone articulates. The two halves of the pelvic girdle meet ventrally to form the pubic symphysis containing (iv) cartilage.

  1. (i) Clavicle (ii) Scapula (iii) Sternum (iv) Glenoid

D Correct answer
Explanation

The pelvic girdle is composed of two coxal bones, each formed by the fusion of the ilium, ischium, and pubis. The acetabulum is the cup-like cavity where these three bones meet and the femur articulates, and the pubic symphysis contains fibrous cartilage.

A Correct answer
Explanation

The hip bone or innominate bone or coxal bone is a large, flattened, irregularly shaped bone. It consists of three parts, the ilium, ischium, and pubis, which are fused in the adult.

Match column I with column II and select the correct option from the codes given below.  


Column I(Skeletal Part)   Column II(Number of bones)
A.Cranium   (i) 22
B. Skull(Cranial and facial bones)  (ii) 8
C. Face (iii) 14
D. Hind limb  (iv) 24
E. Ribs (v)  30

  1. A-(i), B-(ii), C-(iii), D-(v), E-(iv)

  2. A-(ii), B-(i), C-(iii), D-(v), E-(iv)

  3. A-(i), B-(ii), C-(iii), D-(iv), E-(v)

  4. A-(v), B-(iv), C-(iii), D-(ii), E-(i)

B Correct answer
Explanation

The cranium consists of 8 bones, the face has 14, the skull (cranium + face) has 22, the hind limb has 30, and the rib cage has 24. Matching these gives A-(ii), B-(i), C-(iii), D-(v), E-(iv).

In newborn roofing bones of the skull leave soft gaps called as the ______

  1. Sutures

  2. Fontanelle

  3. Symphasis

  4. gap junctions

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
An infant's skull is made up of 6 separate cranial (skull) bones:
  • Frontal bone
  • Occipital bone
  • Two parietal bones
  • Two temporal bones
These bones are held together by strong, fibrous, elastic tissues called sutures. Also, the soft spaces between the bones that remain open in babies and young children are called fontanelles. Sometimes, they are called soft spots. These spaces are a part of normal development. 

So, the correct option is 'Fontanels'.

Multiple choice zoology production of food from animals animal breeding animal husbandry and its importance introduction to animal husbandry

Animal husbandry and plant breeding programmes are the examples of

  1. Reverse evolution

  2. Artificial selection

  3. Mutation

  4. Natural selection

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Animal husbandry and plant breeding programmes are the examples of artificial selection. The artificial selection is the modification of species by selective breeding. Animals or plants with desirable characteristics are interbred with the aim of altering the genotype and producing a new strain of the organism for a specific purpose. Traditional breeding techniques have been supplemented by more recent methods of genetic engineering, genetic testing and embryo manipulation. Sequencing of genomes of commercially important animals and plant species has enabled the inheritance of desired genes to be monitored directly by molecular methods.

So, the correct answer is 'Artificial selection'.
