Question

How does the regulation of gene expression support continued evolution of more complex organisms?

a) It reduces genetic variability.
b) It allows for rapid adaptation to environmental changes.
c) It increases the stability of genes.
d) It limits mutations.

Answer 1

The regulation of gene expression in complex organisms supports evolution by enabling adaptation to environmental changes and cell specialization, conserving energy and resources, and increasing gene stability.

Step-by-step explanation:

The regulation of gene expression in complex organisms supports continued evolution by allowing for rapid adaptation to environmental changes and enabling cells to become specialized within a multicellular organism. This regulation conserves energy and resources, as it is more efficient for an organism to turn on genes only when they are required. Additionally, it increases the stability of genes and ensures that cells can grow larger to accommodate protein synthesis.
