Answer:
The comparison of a measurement with a known standard, used to determine whether the measurement is reliable. Measurement accuracy is identified as the difference between the measurement of a factor and the accepted value for that factor from a trusted external source, or the percentage by which the two values differ.
Explanation:
Heterospory, highly reduced gametophytes, ovules, pollen, seeds are the five adaptations common to all seed plants that ensure their success in the adaptation to land. Three things: The gametophytes of seed plants are reduced and dependent upon the parent sporophyte which protects them (particularly in the case of the female gametophyte). Pollen is covered with sporopollenin which is resistant to physical factors in the environment. The structure of the seed protects the next generation sporophyte and allows it to remain dormant until conditions are right for germination, development and growth.
Answer:
Plate Boundaries

Puerto Rico might be on a plate boundary. When two plates slide against each other (also called a transform boundary) they can cause a earthquake to happen on the surface.
At higher latitudes, climates become colder. The closer you are to the ground, the warmer it will be, but if you're far from the ground, it'll be cold.
