Answer:
The correct answer would be B. fatty acids, DNA.
The other options show the pairing of polymer and their monomer units.
For example, proteins are the polymers of amino acids, starch is polymer made up of several glucose units.
Similarly, DNA or deoxyribonucleic acid is a double stranded molecule made up of nucleotides (not fatty acids) attached via phospho-di-ester bond.
The nucleotide is consisted of deoxyribose sugar, a nitrogenous base, and phosphorus group.
Thus, fatty acids and DNA make the inappropriate pairing as compared to other options.
2. Falling sea levels and colliding continents created connections between continents that led to great movements of land animals during the Neogene Period is the correct statement.

Answer:
This question lacks options, options are: a. Keystone species b. Dominant species c. Competitor species d. Omnivore species e. Mutualistic species. The correct answer is a.
Explanation:
The most connected species from a trophic point of view in an ecosystem are keystone species, since their elimination has great effects on the stability and persistence of the network. The Keystone species are those species that play a crucial role in the structure and dynamics of a certain ecosystem and that, in the event of their disappearance, would be seriously unbalanced. These species are responsible for the physical structure of the habitats of many other species, and they play an important role in the succession processes of ecosystems. Elephants play an important role in maintaining the structure and balance of ecosystems in these communities, therefore they are keystone species.
