Answer:
Hydrogen Bonding. A hydrogen bond is a weak type of force that forms a special type of dipole-dipole attraction which occurs when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons

Protein breakdown into amino acids is the statement that correctly explains the complex molecule.
Option (c);
<u>EXPLANATION:</u>  
Cells in our body carry put several chemical reactions which in turn keep us healthy. All these reactions are collectively called metabolism. With the breakdown of complex molecules, it releases a lot of energy into the body.Through this process, Proteins are broken down into amino acids. 
Various enzymes, specifically pepsin and hydrochloric acid breaks proteins into individual amino acids. They on further broken into a-keto acids. These amino acids reduces body weight and improves energy in the human body.

Answer:
12 : 3 : 1
Explanation:
According to Mendel's principles, a dihybrid cross between two heterozygous summer squash parents (WwGg X WwGg) should yield offsprings, 12 with white, 3 with yellow and  1 with green color phenotype. The classic Mendelian phenotypic ratio for dihybrid cross is 9:3:3:1. In this case, genotypes W- G- and W- gg produce white color phenotype. This is because we have 12: 3: 1 phenotypic ratio in which the alleles of two different genes assort independently into gametes.
<em>Dihybrid cross for heterozygous summer squash:</em>
                      WG         Wg            wG            wg           
      WG       WWGG   WWGg     WwGG     WwGg
      Wg        WWGg   WWgg     WwGg      Wwgg
      wG        WwGG    WwGg     wwGG      wwGg
       wg        WwGg    Wwgg     wwGg        wwgg
    Genotypes:
    W-G-  and W- gg  = white = 12
     ww G- = yellow = 3
      ww gg = green = 1
