Asample has a c614 activity of 0.0015 bq per gram of carbon.
(a) find the age of the sample, assuming that the activity per gram of carbon in a living organism has been constant at a value of 0.23 bq.
(b) evidence suggests that the value of 0.23 bq might have been as much as 45% larger. repeat part (a), taking into account this 45% increase.

Choose all that apply. when creating a graph, you should: determine the x- and y- variables label the scale on the x- and y- axes plot the data points draw a line of best fit to represent the data trend

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
