The right answer answer is the same species.

* Pregygotic barriers prevent mating or ovum from being fertilized if different species attempt to mate. There are four barriers in this category.

* Postzygotic barriers occur after fertilization between different species. The hybrid zygote formed may be abnormal or infertile. There are three barriers in this category.

-The non-viability of hybrids

-The sterility of hybrids

-The lapse of hybrids

In general, healthy men are represented by white squares, while sick men are represented by colored squares (most often in black).

Describe the structures of proteins and nucleic acids, and then explain the relationship between these two molecules within a ce
barxatty [35]
<span>Proteins are large biological molecules consisting of one or more chains of amino acids.  Proteins differ from one another primarily in their sequence of amino acids, which is decided by the nucleotide sequence of their make-up, and which usually results in folding of the protein into a three-dimensional structure that determines its job. 
    </span><span>Nucleic acids are linear polymers (chains) of nucleotides. Each nucleotide consists of three things: a purine , nitrogenous base a pentose sugar, and a phosphate group.  
    </span><span>
 Basically Proteins are chains of amino acids, nucleic acids are chains of nucleosides (base+sugar+phosphate), and the sequence of nucleic acid results in the specific sequence of amino acids in the protein, finnally determining its shape and function. </span>
