What is the final step of the following process: - Solar radiation reaches Earth's atmosphere - 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
----
Answer: The Earth's temperature rises

Q: What is the final step of the following process: - Electrical signals in the brain travel through nerves to muscles - Two types of proteins exist in filaments in the muscles - The filaments move when the brain instructs them to - The motion of the filaments cause the muscle to shorten and contract
A: Opposing pairs of muscles exist in order to provide the necessary range of motion.

[Q]: What is the final step of the following process: - Bacteria enter the body - Bacteria start to divide and grow - The uncontrolled growth takes away resources from other cells - Other cells cannot function properly - We feel unwell - The growth and division of bacteria produce toxins - Toxins harm the body - The body tries to react to the toxins
****
