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.

The fact that there appears to be a genetic component to inflammatory bowel disease, but that it does not show clear Mendelian i

Vesnalui [34]

Answer:

Option D

Explanation:

(the gene for the disease has incomplete penetrance. the gene for the disease has limited expressivity. the disease is polygenic) - all these are examples of non-mendelian inheritance which include incomplete penetrance, polygenic inheritance etc. These do not follow the mendelian pattern of inheritance.

(the gene for the disease is recessive.)- this shows the mendelian pattern of inheritance... Dominant and recessive characteristics are examples that show Mendelian inheritance.
