|---|---|
| A. Axoneme | I. Centriole |
| B. Cartwheel pattern | II. Cilia and flagella |
| C. Crista | III. Chromosome |
| D. Satellite | IV. Mitochondria |

Consider the following statements:
A. Annelids are true coelomates B. Poriferans are pseudocoelomates C. Aschelminthes are acoelomates D. Platyhelminthes are pseudocoelomates
Choose the correct answer from the options given below:
Annelids — true coelomates (correct). Poriferans — acoelomates; Aschelminthes — pseudocoelomates; Platyhelminthes — acoelomates.
Which of the following is not a steroid hormone?
Glucagon is a peptide hormone (29 aa); the others are steroids derived from cholesterol.
Given below are two statements:
Statement I: In the nephron, the descending limb of loop of Henle is impermeable to water and permeable to electrolytes.
Statement II: The proximal convoluted tubule is lined by simple columnar brush border epithelium and increases the surface area for reabsorption.
In the light of the above statements, choose the correct answer from the options given below:
Descending limb is permeable to water and impermeable to electrolytes (the opposite of what is claimed) — Statement I is false. PCT lining is correct.

| C. Widal test | III. Rhinoviruses |
| D. Allergy | IV. Dust mites |
Choose the correct answer from the options given below:
Common cold — rhinoviruses; haemozoin — malarial pigment from Plasmodium; Widal test — typhoid; dust mites trigger allergy.

| List I (Sub Phases of Prophase I) | List II (Specific characters) |
|---|---|
| A. Diakinesis | I. Synaptonemal complex formation |
| B. Pachytene | II. Completion of terminalisation of chiasmata |
| C. Zygotene | III. Chromosomes look like thin threads |
| D. Leptotene | IV. Appearance of recombination nodules |
Choose the correct answer from the options given below:
Leptotene — thin threads; Zygotene — synapsis (SC); Pachytene — recombination nodules; Diakinesis — terminalisation of chiasmata.
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R:
Assertion A: Breast-feeding during initial period of infant growth is recommended by doctors for bringing a healthy baby.
Reason R: Colostrum contains several antibodies absolutely essential to develop resistance for the new born baby.
In the light of the above statements, choose the most appropriate answer from the options given below:
Colostrum is rich in IgA — passive immunity for the neonate; R explains the medical recommendation in A.
Which one of the following factors will not affect the Hardy-Weinberg equilibrium?
"Constant gene pool" describes the equilibrium itself — it does not perturb it. The other three (recombination, drift, migration) are factors that can disturb H-W equilibrium.
