Continuously facing towards the east also helps the flowers to heat up quickly. This gives them an advantage in pollination, as warm flowers attract insects. Therefore, in the plant's interest, the flower always faces the sun and is therefore always clearly visible to these important pollinators.
<span>The answer is A. a sequence of nitrogen bases.
</span><span>Each hereditary trait corresponds to a sequence of nitrogen bases. According to science research and is already proven, nitrogen bases are found in DNA.</span>
The tree topology
The lengths of the branches
The branching order of the tree
Nucleotide substitution rate
These would not affect maximum likelihood estimates of phylogenies when comparing different tree hypotheses.
<h3>What is tree topology?</h3>
- A unique kind of structure called a tree topology has numerous connected parts arranged like the branches of a tree.
<h3>The lengths of the branches:</h3>
- Branch lengths are a sign of genetic divergence; the longer the branch, the more genetic divergence has taken place.
- Usually, we calculate the average number of nucleotide or protein substitutions per site to assess the degree of genetic alteration.
<h3>The branching order of the tree:</h3>
- The topology of a tree refers to its branching structure.
- Species (or higher taxa), populations, genes, and proteins are examples of taxonomic units that the nodes represent.
- A branch is referred to as an edge, and it represents an estimate of the length of time between the evolutionary relationships between taxonomic units.
<h3>What is nucleotide substitution rate?</h3>
- The instantaneous rate of change from each of the four nucleotides to each of the other four nucleotides is summarized in the nucleotide substitution rate matrix.

Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code
