Replacement is the molecule-by-molecule substitution of another mineral of different composition for the original material. The fine details of shell structures and wood are generally preserved. Minerals which commonly replace hard parts are silica and pyrite
Ionic bonds involve the gaining and losing of valence electrons between atoms, while covalent bonds involve the sharing of valence electrons between atoms
Answer:
Explanation:
Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. Despite such variety, proteins also share several specific structural characteristics in their monomers, the amino acids. Structural similarities among amino acids make protein synthesis a uniform and regulated process; however, each amino acid contains a unique structural component as well. Specific differences between each amino acid interact to create unique three-dimensional protein structures. Combined, the similarities and differences between amino acids explain how cells can build a diverse pool of proteins from the same set of building blocks. Protein synthesis involves building a polymer of amino acids with complex three-dimensional structure. Dehydration synthesis forms a peptide bond between amino acids and releases a water molecule.
Answer:
Molecules are two or more atoms chemically joined together
Compounds are two or more different elements joined together chemically(heteronuclear or homonuclear).
Explanation:
All compounds are molecules, but not all molecules are compounds. a molecule can be made of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule, all compounds are made up of two or more different types of atoms.One that is used a lot is water(H2o)
I HOPE THIS HELPS!!!!
I'm pretty sure it's <span>coal, nuclear, & oil, because they are man-made, and they're only good for a one-time use only.</span>
