Drug A is nearly twice (40% better) as good as drug B in elevating pulse because the particular worm used in testing drug B had a higher “resting” (pre-drug) pulse and there was less change to bring it to the same rate as was seen post-drug in worm A. 6.

Nicotinic agonist
A nicotinic agonist is a drug that mimics the action of acetylcholine (ACh) at nicotinic acetylcholine receptors (nAChRs). The nAChR is named for its affinity for nicotine.Examples include nicotine (by definition), acetylcholine (the endogenous agonist of nAChRs), choline, epibatidine, lobeline, varenicline and cytisine.
