Explanation:

Question 15 (Assuming it's about "biome")

A biome is defined as a large geographical area with distinct climate conditions and characteristic organisms. Option a matches this definition. Option b refers to species richness, c to interspecies interactions, d to an individual organism.

The Kyoto Protocol focused on reducing greenhouse gas emissions (like carbon) to combat global warming. Paris Agreement is broader, Geneva Convention is about warfare, Montreal Protocol is about ozone depletion.

Antiparallel in DNA means the two strands run in opposite (5’-3’ and 3’-5’) directions. Option a is double helix shape, b is sugar - phosphate direction (but not antiparallel), d is base pairing.

Answer:

a. A large geographical area with specific climatic conditions
