Suppose that a genetic alteration resulted in the synthesis of cyclin-dependent kinases that no longer provided the "go" signal at the cellular checkpoint. Predict the immediate outcome if this were to alter the normal cell life-cycle processes at the G2 checkpoint. The cells involved would
a. grow and otherwise function undergoing mitosis
b. exit the cell cycle completely and enter a nondividing cellular state
c. most likely remain in suspended metaphase, unable to enter anaphase
d. proceed as normal, enter the G1, S, G2, and M phases and divide

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.
