Answer:
1. Fossil evidence
2. Homologous similarities.
3. Molecular evidence
Begins to decline and die off, because other organisms are competing for those same resources
The polymer's directionality has an impact on its composition and behaviour. The 3' and 5' carbons of the sugar in the nucleotide serve as the ends of nucleic acids.
<h3>How do molecules' form and function influence each other?</h3>
Biological macromolecules' three-dimensional structure dictates how they work. Proteins and nucleic acids have biological activity because of their three-dimensional form.
<h3>Why is directionality crucial to protein structure?</h3>
Proteins are directed molecules, similar to DNA molecules in that regard. On one end of every amino acid is a carboxyl group, and on the other is an amino group. This directionality enables ribosomes to assemble an amino acid chain.

Written above we have an example of a dihybrid cross. When two individuals that are heterozygous for both of the two traits we are observing cross we expect to get four different phenotypes in the ratio of <span> 9:3:3:1 :
9 dominant for both traits : (polka-dot tails and long eyelashes)
3 dominant for one, recessive for the other (polka-dot tails and short eyelashes)
3 recessive for the first one, dominant for the other (solid tails and long eyelashes)
1 recessive for both traits (solid tail and short eyelash)</span>
