In aquaculture ponds, zeolite is applied to selectively trap and adsorb toxic unionized ammonia and ammonium ions ($\text{NH}_4^+$) and bind hazardous metabolic gases (such as hydrogen sulfide, $\text{H}_2\text{S}$), thereby purifying the pond water column and benthic sediment.
Correct Option: Option 3 (Zeolite).

Freshly caught broodstock lobster should be given a dip treatment in to remove polychaete worms,
sponges, and ciliates
Freshly captured spiny and slipper lobster broodstock (Panulirus homarus, Thenus unimaculatus) from natural marine reefs frequently harbor heavy fouling loads of commensal polychaetes, stalked barnacles, and fouling peritrich ciliates (Zoothamnium, Epistylis).
prophylactic chemical dip in formalin ($100-150\text{ ppm}$ bath for 30–60 minutes, or short dip at $200\text{ ppm}$) rapidly detaches epibionts, ciliates, and polychaetes without injuring lobster gill filaments.
Correct Option: Option 3 (Formalin).

Which point in the replication cycle appears most easily blocked by antivirals?
In viral replication kinetics, the most clinically accessible and successful pharmacological target for antiviral therapeutics is viral nucleic acid replication (RNA and DNA polymerase activity).
Nucleoside analogues and polymerase inhibitors selectively terminate viral elongation chains without damaging host cellular replication machinery.
Correct Option: Option 2 (Virus RNA and DNA replication).
