An operon is a stretch of DNA consisting of an operator, a promoter, and genes for a related set of proteins, usually making up an entire metabolic pathway.
operon is a functional unit of gene.
This cluster of gene transcribed together to give a messenger RNA which further give rises to protein.
operator in operon is the site where repressor binds.
promoter is where Mrna binds , where our genes are transcribed
structural genes, they code for the enzyme that are involved in this metabolic pathway.
Operons have an important role to play as they produce protein for the cell this serves them energy, the protein is produced only when energy is required.

The answer is C.
The water inside the potato contains more salt and other minerals than the pure water that surrounds it. Due to this osmosis will occur and the pure water will diffuse into thhe potato to bring down the salt concentration inside the potato
Answer:
Obsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure. It is an amorphous material known as a "mineraloid." The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture (see photo).
hope this helps
Answer:
The adipocytes, also known as the fat cells are very large in concentration. In the negative energy balance, like when the expenditure of energy is taking place, the initial energy source is the fats accumulated in the adipocytes.
There are two enzymes taking part in the procedure, that is, the adipose glyceride lipases and the hormone-sensitive lipase. In the procedure, the fats accumulated in the adipose cells get lost. This leads to shrinkage of the adipose cells, while the number of adipose cells stays similar.
