Ans.

Gametophyte shows haploid, gamete-forming stage of plant's life cycle, while sporophyte shows diploid, spore-forming stage of plant's life cycle. In green algae, gametophytes and sporophytes are isomorphic (indistinguishable). In bryophytes, such as mosses, gametophyte shows dominant stage as it is most visible stage in their life-cycle. In vascular plants, such as ferns and seed plants, sporophytes show dominant stage.  

Thus, 'seed plants show briefest gametophyte stage' and 'mosses show longest gametophyte stage.'

How does a psuedoscorpian differ fron a true scorpion
alisha [4.7K]
Among the most obvious differences between pseudoscorpions and scorpions is size. Scorpions range from a half-inch long to more than 7 inches; many of the commonly encountered scorpions in the United States are 2 inches long or longer, making them easy to spot with the naked eye. Pseudoscorpions, on the other hand, reach between just under one-tenth of an inch to barely over a quarter-inch long, making them inconspicuous in most circumstances. Most are under 1/8 inch.

Novay_Z [31]

Ans.

The first pass effect is defined as a phenomenon of metabolism of drug, in which drug concentration is greatly decreased before reaching the systemic circulation. It represents that fraction of drug lost, at the time of absorption of drug in gut.

Thus, the client is not receiving all the dosage of ingested drug (aspirin) because of the 'first pass effect.'
