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.
<u>Answer:</u>
In the sterilization area instruments should move from a <u>contaminated</u> to a <u>clean </u>area.
<u>Explanation:</u>
Sterilization is the process of destroying, removing, killing or deactivating all the micro-organisms like viruses, fungi, spores, bacteria, unicellular eukaryotic organisms as plasmodium and many more.
This process differ from pasteurization, disinfection and sanitization by reducing rather than removing the micro-organisms and other biological agents. An object is known as sterile or aseptic after sterilization. As the principle for cleaning process in any field is to go through from dirty place to clean place and such that clean the entire area.
Answer:
The Nervous System
The basic workings of the nervous system depend a lot on tiny cells called neurons. The brain has billions of them, and they have many specialized jobs. For example, sensory neurons send information from the eyes, ears, nose, tongue, and skin to the brain.
