C. Is the correct answer I believe
Answer:
Homologous genes that are highly conserved.
Explanation:
Phylogenetic trees are diagrams that represent evolutionary relationship between organisms.
It is set to represent the hypothesis that a set of species evolved fro the same ancestor.
Anatomical similarities are considered in the construction of the trees.
However , two organisms can be placed in the same tree by comparing their genes.
If the two eukaryotes have genes that are highly conserved that similar.
When iodine reacts with starch, it is trapped in the starch's helical structure forming a blue-black precipitate. Iodine is not very water soluble, so in making an iodine solution, potassium iodide (KI) is added. This results in the formation of a triiodide complex, which is completely soluble in water.
All the trophic levels are there, Number ten is asking you to find a chain that includes 7 organisms. Starting from:
Phytoplankton (Producer)
Herbivorous Zooplankton (Primary Consumer)
Carnivorous Zooplankton (Primary Con.)
Artic Char (secondary Con.)
Capelin (tertiary Con.)
Harbor Seal (Quaternary Con.)
Polar Bear(Quaternary Con.)
