input: Please answer the following: What is the missing first step of the following process: - The receptors will lock onto a target cell using these chemical receptors on the surface, which docks onto the cell surface - The receptors then go into the cell - The receptors use it like a factory - The receptors take it over and make it produce thousands or in some cases millions of copies of new viruses - The copies come streaming out of the cell - The copies infect other cells to make more viruses, or they escape from the body and infect a new victim -
++++++++++
output: The flu virus has receptors, which are like viral Velcro, on the surface of the virus particle

Please answer this: What is the missing first step of the following process: - Some is reflected back into space - The rest of the energy is absorbed by land and oceans, heating the Earth - Heat radiates from Earth to space - Some of this heat is trapped by greenhouse gases in the atmosphere - Human activities such as burning fuel are increasing the amount of greenhouses gases - This causes more heat radiation to stay trapped in our atmosphere - The Earth's temperature rises -
