From the options B is not part of the study of science is : ( B ) The ethics of new developments
Analyzing the evidence gotten from an experimental or research study is a core part of science because that way the scientist can determine if the results obtained are close to the predicted hypothesis or outcome.
Science involves the study of the natural world because all scientific experiments and researches are carried out by studying real life ( natural world ) as study cases. while the ethics of new developments is not controlled or determined by the scientist
Hence we can conclude that the ethics of new developments are not part of the study of science

They use Geothermal Energy, which is used from plants to generate electricity.

Carbon film fossil is the type of fossil that preserves delicate details of an organism after pressure squeezes out liquids and gases.
Carbon film fossil is a type of fossil that is mainly composed of carbon and can preserve delicate details of organism’s (animal and plants) parts. The formation of carbon film fossil starts when a dead organism is buried under sediments. After some time, the organism will begin to decay in a process known as carbonization. Pressure will squeeze out liquids and gases from the dead organism, leaving behind a layer of carbon. Carbon film fossils usually appear black or brown in colour.
The sodium hydroxide solution and vegetable oil underwent a chemical change.
<h3><u>Explanation:</u></h3>
The reaction between a base and a fat or fatty acid is called as saponification reaction. Here the base dissociates into the cation and hydroxyl ion. The hydrogen from the fatty acid of the oil reacts with the hydroxyl ion to form water which is basically the neutralization reaction. This cation now reacts with the rest of the fatty acid to form a bipolar molecule which is the soap. During the reaction, the solution becomes cloudy but with time, it again goes back to solution. The cloudyness appears because oil isn't soluble in water based solutions and the base is actually made solution in water.
Here the sodium hydroxide reacts with oil to form water and the soap molecule which is a chemical change.
