Arachidonic acid is the raw material for synthesis of
RUDIKE [14]

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.

Biologists surveying the bacterial flora of Yellowstone National Park, particularly populations located in the park’s famous hot
Goshia [24]

Answer:

The correct answer will be option-B

Explanation:

The data collected on the bacterial species in the Yellowstone national park involved:

1. habitat characteristics

2.DNA of bacteria from each population

3. compared with other species of the park

Based on these features, the biologist could apply all the types of species concept like ecological species concept which allows the study of the species from the same niche.

Also, they compared the DNA of the species of the bacteria and compared them which allows to trace the evolutionary patterns and showing the phylogenetic relationship.

Since bacteria do not reproduce by the sexual reproduction, therefore, a biologist cannot apply the biological species concept which states that species can be called species which can reproduce only with the closely rated species only or the individual of the same species.

Thus, Option-B is the correct answer.
