Problem: - They process it with millions of tiny nephrons - Remove all the waste - The kidneys return the blood back to the body through the renal artery - Send the urine with the waste to the bladder through the ureters. What might be the first step of the process?

A: The kidneys receive blood from the renal artery

Problem: Given the question: - Engines produce carbon dioxide - Living things produce waste - Waste decomposes - Decomposition produces methane - Water evaporates - Water vapor joins the atmosphere - Carbon dioxide, water vapor and methane are greenhouse gases - What might be the first step of the process?
++++++++++++++++++++++++++++++++
The answer is:
People breathe and expel carbon dioxide

input question: - These pores are called stomata - Water is absorbed by the roots and passes through vessels in the stem on its way to the leaves - Chlorophyll absorbs the sun's energy - It is this energy that is used to split water molecules into hydrogen and oxygen - Oxygen is released from the leaves into the atmosphere - Hydrogen and carbon dioxide are used to form glucose or food for plants. What might be the first step of the process????
output answer: Carbon dioxide from the air passes through small pores (holes) in the leaves

- The oxygen travels into the body - Breaks down into glucose - Carbon dioxide is produced by the glucose breakdown - The carbon dioxide is exhaled out of the body through the nose or mouth. What might be the first step of the process?
----
Answer: A person takes in oxygen through their nose or mouth

Q: - They secrete digestive juice 'externally' into the small intestine - There are enzymes for breaking down fats, proteins , and carbohydrates - Digestive juices flows from the pancreas through an excretory duct into the small intestine - When the blood sugar levels rise, as they might after a meal, insulin is released - When blood sugar levels are too low, the pancreas releases glucagon into the bloodstream - What might be the first step of the process?
A: Over 99% of the exocrine pancreas cells produce digestive juices

[Q]: - Melted rock inside the Earth is also called molten rock, or magma - Magma moves up through Earth's crust, but it does not always reach the surface - When magma erupts onto Earth's surface, it is known as lava - As lava flows from volcanoes it starts to cool - Minerals form when magma and lava cool - What might be the first step of the process?
****
[A]:
There are places inside Earth where rock will melt
