Mitosis is a process cell division, where one cell divides into two identical cells. Mitosis consists of four phases ~ prophase, metaphase, anaphase, telophase and cytokinesis
Answer:
Melting ice cubes. Melting solid salts. Sublimation of dry ice into carbon dioxide gas. Evaporating liquid water.
Explanation:
The four levels of protein structure are distinguished from one another by the degree of complexity in the polypeptide chain. A single protein molecule may contain one or more of the protein structure types: primary, secondary, tertiary, and quaternary structure. 1. Primary Structure: describes the unique order in which amino acids are linked together to form a protein.
2. Secondary Structure: refers to the coiling or folding of a polypeptide chain that gives the protein its 3-D shape. There are two types of secondary structures observed in proteins. One type is the alpha (α) helix structure. This structure resembles a coiled spring and is secured by hydrogen bonding in the polypeptide chain. The second type of secondary structure in proteins is the beta (β) pleated sheet. This structure appears to be folded or pleated and is held together by hydrogen bonding between polypeptide units of the folded chain that lie adjacent to one another
3. Tertiary Structure: refers to the comprehensive 3-D structure of the polypeptide chain of a protein.
4. Quaternary Structure: is the structure of a protein macromolecule formed by interactions between multiple polypeptide chains. Each polypeptide chain is referred to as a subunit. Proteins with quaternary structure may consist of more than one of the same type of protein subunit.

Answer:
Kidney disorder is responsible for the disturbance occur in the balance of the body because kidney release certain harmones which are necessary for normal growth.
Explanation: There are three harmones releases by kidney i. e. erythropoietin, calcitriol, and renin. Erythropoietin is released by kidney when oxygen level is low in the tissue. It also controls the production of red blood cells. Calcitriol harmone controls the concentration of phosphorous and calcium in the blood. Renin is responsible for the increase in blood pressure when it is needed. So if the disorder of kidney occurs, imbalance occurs in the body.
