Dr. riehm shows you an unlabeled tissue slide and says the tissue is very resistant to stretching, tearing, and compression. he then asks you what you can conclude about the structure of the extracellular matrix (ecm)

it would be the percentage of food eaten by the flock

i remember doing this lab

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.

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.
