Answer: 1. Dwarf Star 2. Helium to Carbon 3. Xray
Explanation: I just took the test. Trust me!!!
<span>Essentially, cohesion and adhesion are the "stickiness" that water molecules have for each other and for other substances. You can see this in the picture to the right. The water drop is composed of water molecules that like to stick together, an example of the property of cohesion.</span>
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.
Answer:
Muscle contraction is an example of mechanical contraction.
Explanation:
Muscular contraction is the activation of generating tension which appear in the muscle fiber as it does't change the length of muscle and is followed by muscular relaxation.
Muscle contraction is based on force and length.
The process of skeletal muscle contraction is an energy requiring process.
In order to perform mechanical work,actin and myosin utilizes the chemical energy into ATP that ultimately require during muscle contraction and relaxation.
In a working muscle,glucose is released from glycogen that are stored in the muscle by the process of glycolysis in which glucose broken down into ATP that is required by cells and tissues.
