The <span> Nitrogenous bases </span><span> of dna form the rungs, linking the Nucleotides strands together through P</span>hosphodiester bonds . Each rung<span> is made up of two bases that </span>link together and because of their chemical nature, A (<span>adenine ) </span><span>will only </span>link with T (thymine) and G (<span>guanine ) </span><span> will only </span>link with C (<span>cytosine)</span><span>. </span>Nucleotides are joined together<span> to </span>form<span> two long </span>strands <span>that spiral to build a structure called a double helix. If it looks like a ladder, the phosphate and sugar molecules would be the </span>sides<span>, while the bases would be the </span>rungs.

I don’t quite understand the answers that you’ve provided to choose from, but if we are comparing those millions of years to a 24 hour clock, then humans have only been around for 2.88 minutes of out the entirety of life on Earth.
Sorry if this didn’t answer your question, but I hope this somehow helps.
<span>The behavior which is critical that members of the same species be able to recognize one another is courtship.
</span><span>It is a collection of instinctive </span>behaviors<span> which result in </span>mating<span> and eventual reproduction.
</span>Animal courtship may be rather simple which involves a small number of chemical, visual, or auditory stimuli. It may be also be a highly complex series of acts by two or more individuals, using many different modes of communication<span>.</span>
