The answer will be B) MgCl2 because magnesium has 2 valence electrons and is a metal and chlorine has the atomic number of 17 and is a metal and in order to form an ionic compound, you must have 1 metal and 1 nonmetal
Answer:
The right answer is A)The primary structure of a protein is the order of amino acids in a polypeptide, as coded for in the DNA of a gene.
Explanation:
Proteins are aminoacids´s polymers. There are 20 different aminoacids that differs only in their R groups. There are four kind of protein structures:
1) Primary structure: it refers to tha secuence of aminoacids in the protein and is defined by DNA.
2) Secondary structure: it describes the situation in which we can identify repeated segments along the polypeptid chain. There are two secondary structures: alpha helix and beta pleated. This two conformation are held together by interactions between peptidic groups. R groups can interact only if they are small.
3) Tertiary structure: is the three-dimentional conformation of the polypeptid and it is stabilized by hydrogen bonds, electrostatic interactions, hydrophobic interactions and disulphide bonds. Stabilizing bonds can be between peptidic groups (peptide bond).
4)Quaternary structure: it applies for that proteins conformed by different subunits. It describes the conformation and interaction between these subunits in the polypeptid.
Answer:
13
Explanation:
1 proton/neutron has an atomic mass of 1. We ignore the electrons because they are too small. Protons and Neutrons have the same atomic mass, therefore the answer s 6+7=13
Yeah, it sure does
Hope this helps!
