In your lesson, you should be able to find this passage, "One possible cause of the End Triassic mass extinction is an enormous rifting event. It was the largest volcanic event in Earth's history. At the time, the present-day continents were part of a single super continent known as Pangaea. Across this continent, large rift zones were developing as Pangaea started to break up. The volcanism produced would have erupted massive floods of basaltic lavas and released large amounts of gas."
rhe mRNA (messenger RNA) takes the transcribed RNA strand to ribosomes in the in the cytoplasm. Here, tRNA will attach to codons using anticodons. The tRNA will also bring amino acids that will make a polypeptide chain. This makes proteins.
Ocean currents are driven by wind, water density differences, and tides. Oceanic currents describe the movement of water from one location to another. Currents are generally measured in meters per second or in knots (1 knot = 1.85 kilometers per hour or 1.15 miles per hour).
The conditioned stimulus is a previously neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually comes to trigger a conditioned response.
