Answer:
Ligand A and ligand B can cause same cellular responses in a cell when they are attached to different receptors.

Such type of response is present in acetylcholine, while when two different ligands attached to two different receptors, same response will occur. This type of response is present in glucagon and epinephrine etc. ligands are responsible for controlling the transcription process when it binds or attached to the DNA molecule of the cell.

Answer: start seeds as early as mid-January
1 to 1 1/2 inches of water each week
Use as much sunlight as you possibly can
Mulch and prune them
explanation:
Well count how many half lifes it would take to get from 1 to 0.125 first
1 to 0.5 - 1 half life
0.5 to 0.25 - 2nd half life
0.25 to 0.125 - 3rd half life
so essentially it would take 3 half lives to get to 0.125 kg of radium.
Now simply multiply the number of half lives with the half life value given
(3x1620) to get your answer as the number of years that it would take.
Hope this helps
