Answer:
reciprocal exchange of dna
Answer:
The correct answer is E. Arachidonic acid is the raw material for synthesis of eicosanoids.
Explanation:
Arachidonic acid is an essential omega-6 fatty acid formed by a 20-carbon chain with four double bonds. The presence of double bonds causes this molecule to have several sites that can be oxidized, allowing the formation of different lipids with different biological activities.
Arachidonic acid is part of phospholipids in cell membranes, and is the precursor of eicosanoid biosynthesis. Arachidonic acid can be synthesized from linoleic acid, one of the essential fatty acids required by most mammals.
The answer is "Groundwater"
Answer:
Adaptive radiation
Explanation:
Adaptive radiation refers to the evolution of the multiple species from one ancestral species. The force which drives the formation of new species is the change of natural environment like the availability of resources, niche, and many other related changes.
The species adapt themselves to these changes and get transformed into new species.
The formation of a variety of species of finches on the Galapagos island is an example of adaptive radiation. The species formed as a result of the food resources they received on the island.
Thus, Adaptive radiation is the correct answer.
