In the cytoplasmic "pool" of amino acids, tRNAs bind to free amino acids.The ribosome receives the particular amino acid carried by tRNA.
Based on complementary pairing of a triplet code (anticodon) with a triplet code (codon) of the mRNA, the tRNA "delivers" its amino acid in translation phase.
An enzyme creates a peptide link by "hooking" the final amino acid in the chain to the one before it. Each tRNA carries its associated amino acid into the protein chain and adds it to the translation phase growing chain.

The greater the electronegativity difference between two bonded atoms, the longer the bond length, the greater the potential energy in chemical bonds
The greater the electronegativity difference between two bonded atoms, the shorter the bond length, the greater the potential energy in chemical bonds
The greater the electronegativity difference between two bonded atoms, the shorter the bond length, the lower the potential energy in chemical bonds
The lower the electronegativity difference between two bonded atoms, the lower the bond length, the lower the potential energy in chemical bonds
None of the above
The relationship between bond length, electronegativity, and potential energy in chemical bonds: The greater the electronegativity difference between the two bonded atoms, the shorter the bond length, and the greater the potential energy in a chemical bond
Basically, the higher the electronegativity of an atom, the more likely it is to attract pairs of electrons toward itself to form bonds. If the electronegativity difference increases, the bond length will decrease.
High energy is required to break bonds with shorter bond lengths. So, bonds with short lengths have high potential energy.

4.how did the hae iii restriction enzyme distinguish between the taster and nontaster allele? explain in terms of snps.
Answer: See Below
Explanation:
I am not sure if there is a figure that is supposed to go with this question but I will explain the concept.
Resitriction enzymes such as HaeIII recogniize and cut at specific plaindromic sequences of DNA. I have attached the sequence where HaeIII cuts.
If this sequence is changed even by one base pair then the enzyme will not cut. SNPs stand for Single Nucleotide Polymorphisms and are a single base change in the genome. In this case I assume the taster and non-taster alleles are different by an SNP.
Restriction Fragment Length Polymorphism (RFLP) is the actual technique that identifies individuals with certain SNPs by cutting the gene and running it on a gel to see what fragments are created.
If a normal gene has the HaeIII restriction site then the enzyme will cut. If the mutant gene has an SNP at the restriction site then it will not cut.

after the synaptonemal complex disappears, how would any pair of homologous chromosomes be associated if crossing over did not occur? what effect might this have on gamete formation?
There may be a misalignment of homologs during metaphase 1, which could lead to the development of gametes with an aberrant number of chromosomes.

A meiosis-specific structure called the synaptonemal complex (SC) is created between homologous chromosomes during prophase and favors homologs over sister chromatids for DSB repair.
When the synaptonemal complex disappears, any pair of homologous chromosomes be associated if crossing over did not occur each sister chromatid would either be entirely maternal or entirely paternal and would only be connected to its sister, and the two homologs would not be connected in any manner thus leading tot he development of gametes with an aberrant number of chromosomes.
