Alchemy is the process of trying to turn non-gold metals into gold. It was practiced hundreds of years ago by scientists who believed that with the right amounts of heat or chemical reactions, they could make gold. After years of experiments and observations, gold was never produced. Which best describes the practice of alchemy? Alchemy was scientific, because scientists practiced it. Alchemy was scientific, because it included observations and experiments. Alchemy was pseudoscientific, because beliefs came before any observations of success. Alchemy was pseudoscientific, because some successful experiments inspired others.
Answer:
Alchemy was scientific, because it included observations and experiments
Explanation:
Scientific research is one that is done through a series not steps or methods. Observation and experiments are part of the steps in a scientific research.
Scientific research is done through investigation of various theories of science as well as formulating hypothesis. Scientists do not just resort to picking random answers concerning the phenomenons around us. They carry out investigations, observations, and would also formulate potential explanations for what is on ground, carry out experiments and then analyze their results to know if they are right or wrong.
Since the question says observation and experiments were done it is scientific

How do the molecular formulas for all the amino acids differ?
The molecular formulas for all the amino acids differ - the R group or side chain.
Each amino acid has the same molecular structure with a central carbon atom, the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.
Each amino acid is exactly the same except for the R group. little side chain represented by the will be different depending on the kind of amino acid.For example, glycine has a hydrogen atom as its R group, whereas alanine has a methyl group (CH3).Thus, the molecular formulas for all the amino acids differ - the R group or side chain.

compared to the surface temperature and luminosity of massive stars in the main sequence, the smaller stars in the main sequence are
Answer:
Betelgeuse
b.Polaris
c. Aldebran
d.Sirius
e. The Sun
Explanation:
arent sure
In comparison with the surface temperature and luminosity of massive stars in the main sequence, the smaller stars in the main sequence are: cooler and less luminous.
A star is a giant astronomical or celestial object that contains a luminous sphere of plasma and bounded together by its own gravitational force.
Generally, a star typically comprises two (2) main hot gases and these are:
I. Hydrogen (H).
II. Helium (He).
Main sequence refer to stars that can fuse hydrogen atoms in its core, to form helium atoms.
Some examples of a main sequence include the following;
Sun (closest to planet Earth). Antares. Canopus. Vega. Betelgeus.The luminosity of a star can be defined as the total amount of light radiated by the star per second. Also, it is measured in Watts (W).
In conclusion, smaller stars in the main sequence are cooler and less luminous than massive stars in the main sequence.

Answer:
The theory of Continental Drift suggest that hundreds of years ago all the continents were one big continent called Pangea. Soon these contintents split up created the places that we live today. This theory was introduced by Alfred Wegener. His colleges thought he was crazy, but later studies proved his impossible theory to be true. By the process of "sea floor spreading" the continents were then ripped apart and drifted to where they are today.
