This is the reason inspite of being at the higher latitude region some indigenous people having darker skin tone needs to have vitamin D as supplements or eat foods rich in VItamin D.

Answer:
The greenhouse effect:
The process in which gases in the atmosphere trap heat from the sun and warm the Earth. is the natural warming of the Earth’s atmosphere Solar radiation enters the atmosphere mainly as light and some of that radiation is absorbed by the Earth’s surface then changed to heat that is reradiated into the atmosphere where it is absorbed by greenhouse gases then reradiated back to Earth again
Ans.
The phosphatases are enzyme molecules that remove phosphate groups from their substrates. In signal transduction pathways, phosphatases deactivate protein kinases by breakdown of phosphoric acid mono esters into free hydroxyl group and a phosphate ion. It causes termination of signal transduction as protein kinases are no longer active to transmit signals.
Thus, the correct answer is 'they inactivate protein kinases to turn off signal transduction.'
