Option B. A man pushes a couch across the room is the answer.
Water (H
2O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. It is by far the most studied chemical compound and is described as the "universal solvent" [17][18] and the "solvent of life".[19] It is the most abundant substance on Earth[20] and the only common substance to exist as a solid, liquid, and gas on Earth's surface.[21] It is also the third most abundant molecule in the universe.[20]
Answer:
C.) crystalline solids
Explanation:
The solid materials may be crystalline or amorphous. The concept of crystal structure is related to the organization of atoms in a geometrical form. Crystalline structures are present in various materials, where atoms distributed within their structure form a network called the crystalline lattice. Therefore, crystalline structures have salts, metals and most minerals. Crystalline structures are formed by unit cells that are their basic unit, as they constitute the smallest set of associated atoms found in a crystalline structure.
The molecules of the crystalline structures can have two types of bonds, the directional ones, which include the covalent and dipole dipole and the non-directional ones where the metallic, ionic, van der Walls bonds. When formed by ionic compounds, these crystalline structures can result in crystalline solids.
All things are considered to abiotic except Bacteria. These are microscopic living beings. That carry out all of the main processes, and some unique ones to live.
The product of the lac z gene is an enzyme, this enzyme do in the bacterial cell that enzyme is known as β-galactosidase, that's an important a part of the metabolism of lactose.
<h3>What are lactose restriction enzyme ?</h3>
When a restriction enzyme along with BamHI is used to reduce the plasmid, it might reduce the circle at one place. The reduce could open up the circle withinside the LacZ gene. This is due to the fact gene cloners have located a bit of DNA that has many limit enzyme reducing in the LacZ gene.
It cleaves (separates) a disaccharide lactose molecule into a ways greater digestible glucose and galactose lacZ encodes β-galactosidase (LacZ), an intracellular enzyme that cleaves the disaccharide lactose into glucose and galactose.
