All seven characteristics must be present simultaneously for something to be considered living. Fill in the remaining characteristics in the following table. Characteristics of a Living Organism1. Order exhibit complex but ordered organization.2. Regulation environment outside an organism may change drastically, but it can adjust its internal environment. They have ability to adapt3. Growth and Development carried by genes controls the pattern of growth and development in all the organisms.4. Response to the environment all organisms respond to environmental stimuli.5. Reproduction organisms reproduce their own kind.6. Evolution reproduction underlies the capacity of populations to change.7. Energy utilization takes in energy and use it to perform all the lifes activities. Part III Write a 200- to 300-word explanation of how atoms make up organic compounds, which make up all living organisms, addressing all three domains. All the organic compounds are made of molecules, where molecules are collections of atoms. All the molecules are made up of many different kinds of atoms through covalent bonds. Most of the atoms are capable of forming small molecules, but carbon is one of the few atoms which can make larger molecules. Carbon can make molecules which have ten, hundreds, or even millions of atoms. So the basic atom in most of the organic compounds is carbon. A single Carbon atom is capable of combining to four other atoms because it has valency of 4. Which means a Carbon atom can form chains and rings onto which other atoms can be attached, which leads to a formation of large number of different compounds. For example Fatty acids contain the COOH group which is attached to hydrocarbon chain or ring. Organic compounds always contain carbon along with other elements such as hydrogen, oxygen, and nitrogen. Monosaccharides are the monomers of carbohydrates Example os carbohydrates are Alcohol, sugar, fat, protein etc..Most of the living organisms are made of Carbohydrates, proteins, and fats. Carbohydrates use carbon, oxygen, and hydrogen. The examples of carbohydrates are sugar, starch, cellulose, and glycogen. Carbohydrates are source of energy in the living organisms. Proteins are the combination of Hydrogen, carbon, oxygen, and nitrogen. Amino acids are the building blocks of the proteins. The sequence of Amino acid in protein is defined by the sequence of a gene, which is encoded in genetic code. In general, genetic code specifies 20 standard amino acids. Examples of proteins are hemoglobin, which is found in red blood cells and carry oxygen to all the cells of body. Lipids are made up of carbon, hydrogen, and oxygen. Lipids store energy and make up cell membranes. Lipids are used mainly to store things. Plants store lipids as oils, and animals store lipids as fats. Lipids are also used to store vitamins. .
