Through the course of evolution, plants have developed smaller gametophytes and larger sporophytes. Study the list of plants. Th
Lapatulllka [165]

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.'

xxTIMURxx [149]

Answer:

a lunar eclipse

Explanation:

The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere. This should not be confused with a solar eclipse which is similar but instead the sun, moon, and earth align in that order which causes the moon to completely block the sun to anyone on earth.

Predict what would happen to muscles if a pesticide that inhibits acetylcholinesterase was present at the motor end plate.
Anarel [89]
If a pesticide that inhibits acetylcholinesterase is present in a muscle, THE MUSCLE WILL BE CONTRACTING REPEATEDLY. 
The enzyme, acetylcholinesterase is the one responsible for the termination of muscle contraction, when this enzyme is deactivated, the muscle contraction will not be turned off and the concerned muscle will contracts repeatedly.
