About 29 of these elements are thought to play an active positive role in life and health in humans. New questions in Biology. But the biggest molecule in nature resides in your body. Collagen (/ ˈ k ɒ l ə dʒ ɪ n /) is the main structural protein in the extracellular matrix found in the body's various connective tissues.As the main component of connective tissue, it is the most abundant protein in mammals, making up from 25% to 35% of the whole-body protein content. The graph below shows the percent by mass of six common elements in the human body What are elements 5 and 6 (most common) A. zinc and sulfur B. sodium and iron C. carbon and oxygen D. chlorine and phosphorus Explanation: H2o (water) is 60% of the human body. Most of the human body is made up of water, H 2 O, with bone cells being comprised of 31% water and the lungs 83%. ... Iodine. In the human body, fibrinogen is necessary for sealing cuts and stopping the loss of blood. By mass, oxygen makes 65% of the human body; but each atom of oxygen weight 16 atomic unit. If this helped please give brainliest answer! A normal human cell has 23 pairs of chromosomes in its nucleus, each a single, very long, molecule … H2o is the molecule for water, meaning that H2o is the most common molecule. It is also the most abundant molecule found in the human body. Narrative asserts the cross-like shape of the laminin molecule is evidence of God's hand in the creation of the human form. HELP PLESAE ITS DUE AT 11:59 What can be said about living organisms and those in the fossil record? The average 70 kg (150 lb) adult human body contains approximately 7 × 10 27 atoms and contains at least detectable traces of 60 chemical elements. Human Body: The human body is composed of a large number of chemical compounds. What is the atomic mass of an atom that has six protons, six neutrons and six electrons? For each carbon atom in our body, there are two hydrogen. Water is the most common molecular subsance found in the human body(~98%). Carbon, Hydrogen, Oxygen and Nitrogen. KatieBrook45 KatieBrook45 Water is the most common molecule in the human body. Since fibrinogen is made of chains of amino acids, it is an example of which type of organic molecule?-carbohydrate-protein-fatty acid-nucleic acid Collagen consists of amino acids bound together to form a triple helix of elongated fibril … Remember the fact that 70% of the human body is made of water? The relative amounts of each element vary by individual, mainly due to differences in the proportion of fat, muscle and bone in their body. Zinc. Most of these compounds are made up of carbon, hydrogen, oxygen, and nitrogen. There are several ways to consider the composition of the human body, including the elements, type of molecule, or type of cells. Water helps deliver oxygen and nutrients to different parts of the body … Water is the most abundant molecule on Earth's surface. Which of the following is a trace elements in the human body? It is chromosome 1. David Mikkelson Published 20 May 2008 H2o is the most common molecule in the human body. and phosphorous is the most abundant element in human body. H2o is the most common molecule in the human body.   Therefore, it isn't surprising that most of a human body's mass is oxygen. Same thing for each oxygen atom, since most of the oxygen in the human body is in the form of water, and there are two hydrogen atoms for each oxygen in a water molecule.
