Structural Organisation in Animals · Question 45

The terga, sterna and pleura of cockroach body are joined by :

1. Cartilage
2. Cementing glue
3. Arthrodial membrane
4. Muscular tissue

Choose the correctly matched pair :

1. Adipose tissue – Dense connective tissue
2. Areolar tissue – Loose connective tissue
3. Tendon – Specialized connective tissue
4. Cartilage – Loose connective tissue

Choose the correctly matched pair:

1. Inner surface of bronchioles - squamous epithelium
2. Moist surface of buccal cavity - Glandular epithelium
3. Inner lining of salivary ducts - Ciliated epithelium
4. Tubular parts of nephrons - Cuboidal epithelium

What external changes are visible after the last moult of a cockroach nymph ?

1. Both fore wings and hind wings develop
2. Mandibles become harder
3. Labium develops
4. Anal cerci develop

Which one of the following is one of the paths followed by air or O2 during respiration in the adult male Periplaneta americana as it enters the animal body?

1. Spiracle in metathorax, trachea, tracheoles, oxygen diffuses into cells
2. Mouth, bronchial tube, trachea, oxygen enters cells
3. Spiracles in prothorax, tracheoles, trachea, oxygen diffuses into cells.
4. Hypopharynx, mouth, pharynx, trachea, tissues

Select the correct option with respect to Cockroaches :-

1. Nervous system comprises of a dorsal nerve cord and ten pairs of ganglion
2. The fore wings are tegmina which are used in flight
3. Malpighian tubules convert nitrogenous wastes into urea
4. Males bear short anal styles not present in females

Identify the tissue shown in the diagram and match with its characteristics and its location :- [Figure]

1. Smooth muscles, show branching, found in the walls of the heart.
2. Striated muscles, tapering at both-ends, attached with the bones of the ribs
3. Skeletal muscle, shows striations and closely attached with the bones of the limbs
4. Cardiac muscles, unbranched muscles, found in the walls of the heart
