PLI CAN SOMEONE CAN HARLP ME As Betty waits, she counts the number of waves that pass her during a 10-second period; she counts just 1 She estimates that the distance between crests is 6 meters. Betty sees the perfect wave and begins paddling. She pushes herself up, stands on the surfboard and rides the wave all the way in to shore, a distance of about 60 meters. It takes her about 10 seconds to ride the wave in. Use two methods to calculate the speed of the wave based pn the information presented. Are they the same? Explain how you got your answers.

In this experiment you were asked to present three possible mechanisms. describe those mechanisms here and include drawings of those mechanisms. how will the bromination of trans-cinnamic acid and trans-stilbene allow you to distinguish between the three possibilities? what would you expect to find in your data in each scenario?

This is a typical grassland food web. it is also a small picture of an important cycle on earth: the carbon cycle. describe how the carbon gets into this food web. a) bacteria and fungi, the decomposers, recycle carbon from dead organisms. b) carbon is found in the grass and is passed from one level to the next in this food web. eliminate c) all living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere. d) plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.
