The sepal of the plant... im pretty sure...
Answer:
Amino acids.
Explanation:
Miller -Urey experiment was performed by creating the primitive earth condition in the laboratory. The main aim of this test was to determine the chemical origin of the life.
The electrodes was used to create the spark conditions and different gases like water, methane, ammonia, and hydrogen. The product was obtained after some days of the reaction. The amino acids like glutamic acid, glycine, α-alanine and β-alanine was obtained from the product of this experiment.
Thus, the correct answer is option (1).
Answer:
when there's an increase in temperature they respond accordingly
Answer:
repeat the same experiment and obtain the same result
explanation...
Getting the same result when an experiment is repeated is called replication. If research results can be replicated, it means they are more likely to be correct.
Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.
I believe the answer is B, The magnetic properties of rocks along the mid-oceanic ridges change alignment in a symmetrical manner
