- Carbon dioxide from the burning fossil fuels enter the atmosphere - The make-up of the atmosphere changes - Some energy from the sun cannot escape back through the changed atmosphere - The earth begins to heat because of the extra trapped energy - Human beings cut down trees - Human beings do not re-plant the trees - Trees cannot help take the extra carbon dioxide from the atmosphere - The extra trapped energy starts to change the earth's short term weather - Eventually the long-term climate patterns start to change - What might be the first step of the process?
----
Answer: Human beings burn fossil fuels (oil, gas, etc.)

Q: - Blood is carried to the kidneys through the renal arteries - The kidneys contain filters inside - The filters capture the waste products - The waste is combined with water to make urine - The urine leaves the kidney and is collected in the bladder - The cleaned blood is returned to the body. What might be the first step of the process?
A: Waste products are deposited in the blood

Answer: Oxygen enters the body through the mouth or nose

[Q]: - Food begins to be processed by the digestive system - The pancreas releases enzymes to aid digestion - Digested food affects the amount of sugar in the blood - The pancreas releases one hormone to lower the blood sugar (glucose) level - The pancreas releases another hormone to raisethe blood sugar (glucose) level. What might be the first step of the process?
****
[A]: Food enters the body

input: Please answer the following: - Waste enters the kidneys - A processing moment in the kidneys let waste and fluid pass - Prevents larger molecules to pass - Fluid goes back to the bloodstream - Bad waste is removed - The final product is turned into urine. What might be the first step of the process?
++++++++++
output: Fluid

- The atoms become unstable - The atoms split - In alpha decay, two protons and two neutrons are released from the atom - In beta decay, a neutron changes into a proton and an electron - The proton joins the nucleus of the atom - The electron is released - What might be the first step of the process?
----
Answer:
The nuclei of some atoms have too few or too many neutrons
