Explanation:
I'm unsure on what your lab was about or what you experimented but I'll give you a definition of the carbon cycle.
The carbon cycle is the process in which carbon gets moved around in all the hemispheres of the earth. For example, atmosphere, geosphere, pedosphere, biosphere, etc. Carbon is very important not only many minerals but all biological compounds.
Best of Luck!
The right options are;
determine the x- and y- variables
plot the data points
draw a line of best fit to represent the data trend
A graph is a diagram which displays the relationship between two or more measurements or numbers using curve, line or bars. When creating a graph, it is important to determine the x- and y- variables. An independent variable is usually represented on the X-axis (horizontal line) while a dependent variable is usually represented on the Y-axis (vertical line). The data points should be plotted and connected by drawing a line, curve or bars to represent the data trend.
Answer:
An index fossil is a fossil used to determine the age of the sediments in which it is found. When quickly approximating the age of new finds, an archaeologist looks at the rocks in which it is buried, as those sediments would have been on the surface at the time of the death of the pre-historic creature.
