Which result from the Miller and Urey experiment provides evidence that the molecules of life could have spontaneously been produced in the ancient Earth environment?
a
After their experiment, they produced DNA from amino acids.
b
They showed how DNA can be produced from simple molecules that included water, oxygen, carbohydrates, and lipids.
c
Their experiment produced amino acids—the building blocks of life—from chemicals that existed in the environment of ancient Earth.
d
Miller and Urey's experiment provided evidence that showed that although oxygen was lacking in the environment of ancient Earth, it could be readily made from the decomposition of rocks and minerals.

- A researcher studies a mutation that occurs in humans and writes four facts about the mutation in a chart. 1. The mutation is caused as a result of chance. 2. The mutation leads to a genetic disease. 3. The mutation occurs in sperm cells and is passed to the next generation. 4. The mutation is not discovered or fixed by the cell's enzymes.
