Answer:
Explanation:
RNA is single-stranded, not double-stranded: Unlike Dna polymerases, RNA polymerases are able to join RNA nucleotides together without requiring preexisting strand of RNA.
Answer:
Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the high pressure system to the low pressure system, causing wind. The wind will carry moisture since it is coming from the ocean.
Explanation:
Winds refers to the movement of air which are produced due to differences in air pressure.
These pressure differences are to uneven heating of the earth by the sun. Due to the uneven shape of the earth, regions around the equator receive a fairly consistent heating from the Sun. However, with increase in latitude north and south, there is more uneven heating of the earth's surface by the Sun. When air is heated, warm air rises up to the atmosphere. This produces a pressure difference and subsequently cold air sinks downward to replace it. This constant air movement results in winds. The winds generated moves from a high pressure system to a low pressure system. The greater the pressure difference, the greater the wind force.
When warm air from land rises, air from the ocean in to replace it. The wind coming from the ocean is moisture-laden, and results in precipation on land.
