The Earth reaches its perihelion (the point in its orbit when it is closest to the sun) during the month of January (around January 3rd currently), which falls durin â¦ g the season of winter in the northern hemisphere.
The most important combination of elements for all living organisms is water which is made up of hydrogen and oxygen. Another very important compound for living organisms is glucose which constitutes Carbon, oxygen and hydrogen. Nitrogen is an important part of proteins. Water, proteins and glucose are the most important things for living things and all these compounds are made up of elements which reflects their importance.
Carbon. If you separate a living organism into its molecular parts, you will find about 70% water. The remainder of each organism is composed of organic molecules, which are necessary for life on Earth. Covalent bonds between carbon and hydrogen atoms form the basis of organic molecules.Other elements such as oxygen, nitrogen, and phosphorus play key roles in life processes by modifying the structure and chemical properties of organic molecules.he unique number and arrangement of bonds between carbon atoms creates a structurally diverse set of organic molecules in nature. These molecules may be constructed in straight, branched, or ringed carbon chains and may include varying numbers of carbon-carbon single, double, or triple bonds.
