Walking does not contribute to global warming.
<u>Answer</u>:
The nucleus is primarily stores most of the cell's DNA.
<u>Explanation</u>:
It is made up of two chains which coils around each other, together they form a helical structure tat further carries the genetic information, which will help in the development, functioning and also the growth and reproduction in all known organism and in viruses. The nucleus is stored in it and the nucleus has the genetic material. They are composed of the nucleotides, in which each nucleotide has four nitrogen. These nucleotides are together joined with covalent bond to each other. Together they have the biological information.
Because dna is found on histone proteins in the nucleus and it cannot exit the nucleus each time info for protein making is needed
Answer:
The order of bonds in increasing order of bond strength would be Ionic, peptide, polar covalent, non-polar covalent hydrogen bond.
Ionic bonds are the strongest bonds which are formed by transferring of valence electrons between different atoms. For example, a bond between sodium and chlorine atoms in NaCl.
A peptide bond is a type of covalent bond formed between a carboxylic group of one amino acid and the amino group of another amino acid. It is provided with extra stability through resonance.
A covalent bond is a type of bond which is formed by the sharing of electrons between two atoms.
They bond strength of these bonds is less than that of ionic bonds and more than that of hydrogen bonds.
Hydrogen bonds are weak bonds formed through electrostatic interactions between a proton present in one molecule and an electronegative atom in another molecule.
