The correct answer is (b) Secondary succession
Secondary succession is the phenomenon in which redevelopment of species takes place when the native species of a region dies. In 1988, secondary succession was seen in the Yellowstone Park. The year faced drought conditions because of fire. A large area was burned as a result of forest fire. This fire destroyed a large area of botanical life. Life survived and redeveloped, there was growth of some plant species. Some pine saplings were also seen after the growth of grass, more animals migrated into the forest and the biodiversity started again as a result of secondary succession.

<h3><u>Answer;</u></h3>
b). Activation of an upstream guanine nucleotide exchange factor
<h3><u>Explanation</u>;</h3>
- <em><u>When a ligand activates the G protein-coupled receptor, it induces a conformational change in the receptor that allows the receptor to function as a guanine nucleotide exchange factor (GEF) that exchanges GDP for GTPthus turning the G protein-coupled receptor on.</u></em>
- The activated G-protein then dissociates into an alpha (G-alpha) and a beta-gamma complex.
