How does pkc’s signaling role change in response to growth factor signaling versus an immune response?
pkc interacts directly with signaling molecules in both cascades, but only exhibits kinase activity during growth factor signaling.
pkc interacts directly with signaling molecules in growth factor cascades, but interacts with signaling inhibitors during immune signaling.
pkc amplifies growth factor cascades, but turns off immune cascades.
pkc is activated during growth factor cascades, but is inactivated during immune response cascades.

1. the geologists have established a set of principals that can can be used o determine the relative ages of rock. this principal is applied to sedimentary and volcanic rocks. the rocks exposed to wall of grand canyon has layers and by studying the number of horizontal layers in the rock(strata) the relative age can be determined. the layer first formed will appear at the bottom and the the layer of strata last formed appear at the top. by using this information the approximate age of rocks can be determined.

2. carbon dating is used to find the relative age of rock in numbers which means for the rocks that has age between 1-70,000 years.

3. for the rocks of age range between 1,000 - billion of years potassium-argon dating is used.
