Scientists stanley miller and harold urey sealed water, methane, ammonia, and hydrogen in a flask, to simulate earth’s early environment. they exposed the chemicals to electric charges to simulate lighting. what did the process produce? a. nucleic acids b. bacteria c. viruses d. amino acids

The correct answer is D. amino acids.  

Miller and Urey were the ones who tested the chemical origin of life and they supported the theory that the life is formed spontaneously through naturally occurring chemical reactions. They designed the experiment in which the conditions of Earth's early atmosphere were simulated and showed that several organic amino acids had formed spontaneously from inorganic materials like water, methane, ammonia, and hydrogen.

Suzie can measure the HEIGHTS of the plants in metres (m) or centimeters (cm)

Explanation:

According to this question, Suzie Q wants to know how different colors of light effect the growth of plants. She sets up the experiment by exposing 5 ferns of the same species to different colors of light (white, blue, green, red).

After ensuring that some variables called constants like same 20 mL of water, same fertilizer (miracle-grow) etc are the same for all ferns, She then measures the growth of each fern placed under different colors of light.

The independent variable in this experiment is the different colors of light while the dependent variable is the growth of the plants. This question is asking for how Suzie could measure the dependent variable (growth). Suzie can measure the growth of the ferns placed under different colors of light by RECORDING THE HEIGHTS OF EACH FERN IN cm or m.
