Answer: Energy transfer could come through condoctours (metal, or copper) to another object to power a bulb, speaker or any other electrical gizmo. (This can get a brainliest answer)
Answer:
Energy transfer is a process of passing energy into a source that lacks it, like a lightbulb. Energy can be transferred through conductors, that pass through the energy to the goal (lightbulb). Conductors are available inside of the cables you use to connect the power source and the lightbulb together, they are mostly metals, since they are good conductors. When you turn on your lightbulb, with it connected to the cable which is connected to the energy source, the energy passes through the conductor into the goal and turns on your lightbulb. There are other products to prevent energy transfer, they are called insulators, they stop energy transfer and keep it stored inside of them. An example of insulator is silicon, it stores the energy instead of transmitting it and keeps it stored inside without electrifying anyone when touching it.

Which technology is used to study the crystal structure of rocks and minerals?
The study of crystals allows scientists to understand how minerals crystallize as well as their internal structure, relationships, and distribution of atoms, ions, and ionic groups inside the crystal lattice.
What does mineral mean?Minerals are materials that the Earth naturally forms. Minerals are typically inorganic, solid, and have a crystal structure. They are created naturally by geological processes. A single chemical element or, more frequently, a combination may make up a mineral.
Do rocks contain minerals?A mineral is an organic substance that occurs in nature with unique atomic structures, chemical compositions, and physical qualities. In most cases, two or more elements that have been mingled together by erosion and weathering make up the sand.

The three parts of the diagram above are in chronological order. In the space below,
identify the blue segment and the yellow segment, then describe and explain the
process that has occurred. (a four to six sentence paragraph is expected!)
Transcription is the copy process of a segment of the DNA template strand to produce mRNA. The blue segment is DNA, and the yellow segment is mRNA.
What is transcription?The first step before protein arrangement is to synthesize messenger RNA, mRNA.
Transcription is the synthesis of the messenger RNA, mRNA. This event occurs in the nucleus and uses fragments of DNA molecules to do it.
When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: the coding strand and the template strand.
The coding strand goes in direction 5' to 3', The complementary strand -template strand- grows in direction 3' to 5'.
The template strand is the one that is going to be complemented by the mRNA. RNA polymerase is in charge of reading the original DNI strand for mRNA synthesis.
mRNA molecule grows complementing DNA base sequences. This is,
DNA mRNA
adenine ⇔ uracil
guanine ⇔ cytosine
thymine ⇔ adenine
cytosine ⇔ guanine
Once mRNA synthesis is over, the molecule leaves the nucleus to start the transcription process in the cytoplasm.
Answer:
The blue segment is DNA moleculeThe yellow segment is mRNA molecule1- DNA molecule
2- Separation of the DNI molecule into two strands and mRNA molecule growing.
3- mRNA molecule already synthesized and separated from DNA
