Based on this information, what type of transport is used for glucose in blood and intestinal cells? what type of transport is involved in this process?

Transport active.

Explanation:

Glucose is the main source of cellular energy. It is captured by most cells in the body through carrier proteins present in the plasma membrane in favor of their concentration gradient. On the other hand, in intestinal epithelial cells and renal tubules, glucose is captured against its concentration gradient using apical membrane transport proteins and then exits the cell through the basement membrane to enter the bloodstream, in favor of its concentration gradient using membrane carriers known as GLUT's.

Glucose uptake by intestinal epithelial cells always occurs by active transport because it uses a membrane protein in transport even when it is in favor of the concentration gradient.

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.
