Match the following scientific terms with their appropriate descriptions:
textbf{Step 1:} ELISA (A) stands for Enzyme-Linked Immunosorbent Assay, a test that detects the presence of an antigen by using an antibody linked to an enzyme. This matches with description IV, where the antibody is linked to an enzyme.
Step 2: RNAi (B) refers to RNA interference, a process that prevents gene expression by silencing specific genes. This corresponds with description III, which talks about gene expression prevention.
Step 3: GEAC (C) stands for Genetic Engineering Approval Committee, an organization that ensures the safety of genetically modified organisms (GMOs). Therefore, it matches with description II, which focuses on the safety of GM organisms.
Step 4: GMO (D) refers to a Genetically Modified Organism, which is an organism with an altered gene.
Hence, this corresponds with description I, which refers to an altered gene.
Conclusion: The correct matching is:
A-IV (ELISA — Antibody linked to enzyme)
B-III (RNAi — Gene expression prevention)
C-II (GEAC — Safety of GM organisms)
D-I (GMO — Altered gene)
Statement I: Epinephrine attaches to liver cell membrane receptors and activates adenylate cyclase.
Statement II: The cyclic-AMP activates phosphorylation and converts glycogen to glucose.
Assertion (A): Rhodospirillum is not a photoheterotroph bacteria.
Reason (R): Photoheterotrophs obtain energy from light but carbon from organic sources.
Assertion (A): New cells are always being added to the plant body by the activity of the meristem.
Reason (R): The cells/tissues arising out of the same meristem have different structures at maturity.
