Answer:
Water soluble hormones bind to a cell surface localized receptor initiating a signaling cascade using intracellular second messengers for example epinephrine.
Hormone binding activates the G-protein and G-protein activates the adenylyl cylase and it catalyzed the conversion of ATP to cAMP which is second messenger in this pathway. cAMP activate the protein kinase and then protein kinase activate certain cytoplasmic protein which alter the activity of cell.
The hydrogen bonds between complementary nucleotides is what keeps the two strands of a DNA helix together.

What is deforestation?</h3>
- Deforestation, also known as forest clearance, is the removal of a forest or tree stand from land before it is put to another use other than that of a forest.
- Deforestation can occur when forestland is converted to agricultural, ranching, or urban uses. Tropical rainforests experience the highest concentration of deforestation. At the moment, woods encompass about 31% of the Earth's land area.
- This represents a loss of one-third of the forest cover that existed prior to the development of agriculture, with the last century accounting for half of that loss. An area the size of Bangladesh's forest is lost each year between 15 and 18 million hectares. 2,400 trees are typically felled every minute.
