A certain population of beavers builds dams across a stream to catch fish. Some years the stream carries more water than other years. The data below was collected by scientists studying the stream over a sixteen year period.

Years Average Stream Depth
(meters) Average Number of
Beaver Dams Average Number of
Beavers
2000-2003 1.20 6 17
2004-2007 0.92 4 12
2008-2011 1.45 7 21
2012-2015 0.78 2 9

If the average depth of the stream for the next 4 years is 1.60 meters, which of the following is most likely to occur?

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

propane is burned to provide the heat in many cooking grills. the chemical reaction for this process is shown in the equation below.

c3h8 + 5o2 ? 3 co2 + 4h2o + energy

what are the products in this chemical reaction?

3co2 + 4h2o + energy
