Match List I with List II:
| List I | List II |
|---|---|
| A. Fibrous joints | I. Adjacent vertebrae, limited movement |
| B. Cartilaginous joints | II. Humerus and Pectoral girdle, rotational movement |
| C. Hinge joints | III. Skull, don't allow any movement |
| D. Ball and socket joints | IV. Knee, help in locomotion |
Choose the correct answer from the options given below:
Fibrous — skull (immovable); cartilaginous — vertebrae; hinge — knee; ball-and-socket — humerus/pectoral girdle.
Following are the stages of cell division:
A. Gap 2 phase B. Cytokinesis C. Synthesis phase D. Karyokinesis E. Gap 1 phase
Choose the correct sequence of stages from the options given below:
Cell cycle: G1 (E) → S (C) → G2 (A) → karyokinesis (D) → cytokinesis (B).
The "Ti plasmid" of Agrobacterium tumefaciens stands for:
Ti = Tumour-inducing — it produces crown gall tumours in dicots; modified Ti is used as a plant gene-transfer vector.
Match List I with List II:
| List I | List II |
|---|---|
| A. Pons | I. Provides additional space for Neurons, regulates posture and balance |
| B. Hypothalamus | II. Controls respiration and gastric secretions |
| C. Medulla | III. Connects different regions of the brain |
| D. Cerebellum | IV. Neuro secretory cells |
Choose the correct answer from the options given below:
Pons literally means "bridge" — connects brain regions. Hypothalamus contains neurosecretory cells. Medulla controls respiration. Cerebellum manages posture and balance.
Match List I with List II:
| List I | List II |
|---|---|
| A. Axoneme | I. Centriole |
| B. Cartwheel pattern | II. Cilia and flagella |
| C. Crista | III. Chromosome |
| D. Satellite | IV. Mitochondria |
Choose the correct answer from the options given below:
Axoneme — cilia/flagella; Cartwheel — centriole; Crista — mitochondrion; Satellite — chromosome.
